Introduction

- -

-Building Apache Tomcat from source is very easy, and is the first step to -contributing to Tomcat. The complete and comprehensive instructions are -provided in the file BUILDING.txt. -The following is a quick step by step guide. -

- -

Download a Java Development Kit (JDK) version 8

- -

-Building Apache Tomcat requires a JDK (version 8) to be installed. You can download one from
-http://www.oracle.com/technetwork/java/javase/downloads/index.html
-http://openjdk.java.net/install/index.html
-or another JDK vendor. -

- -

-IMPORTANT: Set an environment variable JAVA_HOME to the pathname of the -directory into which you installed the JDK release. -

- -

Install Apache Ant 1.9.8 or later

- -

-Download a binary distribution of Ant 1.9.8 or later from -here. -

- -

-Unpack the binary distribution into a convenient location so that the -Ant release resides in its own directory (conventionally named -apache-ant-1.9.x). For the remainder of this guide, -the symbolic name ${ant.home} is used to refer to the full pathname of - the Ant installation directory. -

- -

-IMPORTANT: Create an ANT_HOME environment variable to point the directory ${ant.home}, -and modify the PATH environment variable to include directory -${ant.home}/bin in its list. This makes the ant command line script -available, which will be used to actually perform the build. -

- -

Checkout or obtain the Tomcat source code

- -

- Tomcat SVN repository URL: - https://svn.apache.org/repos/asf/tomcat/trunk/ -

- Tomcat source packages: - https://tomcat.apache.org/download-90.cgi. -

- -

- Checkout the source using SVN, selecting a tag for released version or - trunk for the current development code, or download and unpack a - source package. For the remainder of this guide, the symbolic name - ${tomcat.source} is used to refer to the - location where the source has been placed. -

- -

Configure download area

- -

- Building Tomcat involves downloading a number of libraries that it depends on. - It is strongly recommended to configure download area for those libraries. -

- -

- By default the build is configured to download the dependencies into the - ${user.home}/tomcat-build-libs directory. You can change this - (see below) but it must be an absolute path. -

- -

- The build is controlled by creating a - ${tomcat.source}/build.properties file. It can be used to - redefine any property that is present in build.properties.default - and build.xml files. The build.properties file - does not exist by default. You have to create it. -

- -

- The download area is defined by property base.path. For example: -

- -

# ----- Default Base Path for Dependent Packages -----
-# Replace this path with the directory path where
-# dependencies binaries should be downloaded.
-base.path=/home/me/some-place-to-download-to

- -

- Different versions of Tomcat are allowed to share the same download area. -

- -

- Another example: -

- -

base.path=${user.dir}/../libraries-tomcat9.0

- -

- Users who access the Internet through a proxy must use the properties - file to indicate to Ant the proxy configuration: -

- -

# ----- Proxy setup -----
-proxy.host=proxy.domain
-proxy.port=8080
-proxy.use=on

- -

Building Tomcat

- -

-Use the following commands to build Tomcat: -

- -

-cd ${tomcat.source}
-ant -

- -

-Once the build has completed successfully, a usable Tomcat installation will have been -produced in the ${tomcat.source}/output/build directory, and can be started -and stopped with the usual scripts. -

Building with Eclipse

- -

-IMPORTANT: This is not a supported means of building Tomcat; this information is -provided without warranty :-). -The only supported means of building Tomcat is with the Ant build described above. -However, some developers like to work on Java code with a Java IDE, -and the following steps have been used by some developers. -

- -

-NOTE: This will not let you build everything under Eclipse; -the build process requires use of Ant for the many stages that aren't -simple Java compilations. -However, it will allow you to view and edit the Java code, -get warnings, reformat code, perform refactorings, run Tomcat -under the IDE, and so on. -

- -

-WARNING: Do not forget to create and configure - ${tomcat.source}/build.properties file as described above - before running any Ant targets. -

- -

-Sample Eclipse project files and launch targets are provided in the -res/ide-support/eclipse directory of the source tree. -The instructions below will automatically copy these into the required locations. -

-An Ant target is provided as a convenience to download all binary dependencies, and to create -the Eclipse project and classpath files in the root of the source tree. -

- -

-cd ${tomcat.source}
-ant ide-eclipse -

- -

-Start Eclipse and create a new Workspace. -

- -

-Open the Preferences dialog and then select Java->Build Path->Classpath -Variables to add two new Classpath Variables: -

- - - - - -

TOMCAT_LIBS_BASE	The same location as the `base.path` - setting in `build.properties`, where the binary dependencies have been downloaded
ANT_HOME	the base path of Ant 1.9.8 or later

- - -

-Use File->Import and choose Existing Projects into Workspace. -From there choose the root directory of the Tomcat source tree (${tomcat.source}) -and import the Tomcat project located there. -

- -

-start-tomcat and stop-tomcat launch configurations are provided in -res/ide-support/eclipse and will be available in the Run->Run Configurations -dialog. Use these to start and stop Tomcat from Eclipse. -If you want to configure these yourself (or are using a different IDE) -then use org.apache.catalina.startup.Bootstrap as the main class, -start/stop etc. as program arguments, and specify -Dcatalina.home=... -(with the name of your build directory) as VM arguments. -

- -

-Tweaking a few formatting preferences will make it much easier to keep consistent with Tomcat -coding conventions (and have your contributions accepted): -

- - - - - - - - -

Java -> Code Style -> Formatter -> Edit...	Tab policy: Spaces only Tab and Indentation size: 4
General -> Editors -> Text Editors	Displayed tab width: 2 Insert spaces for tabs Show whitespace characters (optional)
XML -> XML Files -> Editor	Indent using spaces Indentation size: 2
Ant -> Editor -> Formatter	Tab size: 2 Use tab character instead of spaces: unchecked

- -

-The recommended configuration of Compiler Warnings is documented in -res/ide-support/eclipse/java-compiler-errors-warnings.txt file. -

- -

Building with other IDEs

-The same general approach should work for most IDEs; it has been reported -to work in IntelliJ IDEA, for example. -

- -

Introduction

- -

The CGI (Common Gateway Interface) defines a way for a web server to -interact with external content-generating programs, which are often -referred to as CGI programs or CGI scripts. -

- -

Within Tomcat, CGI support can be added when you are using Tomcat as your -HTTP server and require CGI support. Typically this is done -during development when you don't want to run a web server like -Apache httpd. -Tomcat's CGI support is largely compatible with Apache httpd's, -but there are some limitations (e.g., only one cgi-bin directory). -

- -

CGI support is implemented using the servlet class -org.apache.catalina.servlets.CGIServlet. Traditionally, -this servlet is mapped to the URL pattern "/cgi-bin/*".

- -

By default CGI support is disabled in Tomcat.

Installation

- -

CAUTION - CGI scripts are used to execute programs -external to the Tomcat JVM. If you are using the Java SecurityManager this -will bypass your security policy configuration in catalina.policy.

- -

To enable CGI support:

- -

There are commented-out sample servlet and servlet-mapping elements for -CGI servlet in the default $CATALINA_BASE/conf/web.xml file. -To enable CGI support in your web application, copy that servlet and -servlet-mapping declarations into WEB-INF/web.xml file of your -web application.
- -
Uncommenting the servlet and servlet-mapping in -$CATALINA_BASE/conf/web.xml file enables CGI for all installed -web applications at once.
-
Set privileged="true" on the Context element for your -web application.
- -
Only Contexts which are marked as privileged are allowed to use the -CGI servlet. Note that modifying the global $CATALINA_BASE/conf/context.xml -file affects all web applications. See -Context documentation for details.
-

- -

Configuration

- -

There are several servlet init parameters which can be used to -configure the behaviour of the CGI servlet.

cgiPathPrefix - The CGI search path will start at -the web application root directory + File.separator + this prefix. -By default there is no value, which results in the web application root -directory being used as the search path. The recommended value is -WEB-INF/cgi
enableCmdLineArguments - Are command line parameters -generated from the query string as per section 4.4 of 3875 RFC? The default is -false.
environment-variable- - An environment to be set for the -execution environment of the CGI script. The name of variable is taken from the -parameter name. To configure an environment variable named FOO, configure a -parameter named environment-variable-FOO. The parameter value is used as the -environment variable value. The default is no environment variables.
executable - The name of the executable to be used to -run the script. You may explicitly set this parameter to be an empty string -if your script is itself executable (e.g. an exe file). Default is -perl.
executable-arg-1, executable-arg-2, -and so on - additional arguments for the executable. These precede the -CGI script name. By default there are no additional arguments.
envHttpHeaders - A regular expression used to select the -HTTP headers passed to the CGI process as environment variables. Note that -headers are converted to upper case before matching and that the entire header -name must match the pattern. Default is -ACCEPT[-0-9A-Z]*|CACHE-CONTROL|COOKIE|HOST|IF-[-0-9A-Z]*|REFERER|USER-AGENT -
parameterEncoding - Name of the parameter encoding -to be used with the CGI servlet. Default is -System.getProperty("file.encoding","UTF-8"). That is the system -default encoding, or UTF-8 if that system property is not available.
passShellEnvironment - Should the shell environment -variables from Tomcat process (if any) be passed to the CGI script? Default is -false.
stderrTimeout - The time (in milliseconds) to wait for -the reading of stderr to complete before terminating the CGI process. Default -is 2000.

- -

The CGI script executed depends on the configuration of the CGI Servlet and -how the request is mapped to the CGI Servlet. The CGI search path starts at the -web application root directory + File.separator + cgiPathPrefix. The -pathInfo is then searched unless it is null - in -which case the servletPath is searched.

- -

The search starts with the first path segment and expands one path segment -at a time until no path segments are left (resulting in a 404) or a script is -found. Any remaining path segments are passed to the script in the -PATH_INFO environment variable.

If not building in a Windows - environment, the build scripts assume that Wine is available. If this is not - the case, the skip.installer property may be set to skip the creation of the - Windows installer. - - 1. Configure GPG, if needed - - If the released artifacts have to be cryptographically signed with a - PGP signature, like the official ASF releases are, the following - property can be added to the build.properties file: - - # Location of GPG executable (used only for releases) - gpg.exec=/path/to/gpg - - You do not need it if you do not plan to sign the release. - - If "gpg.exec" property does not point to an existing file, it will be - ignored and this feature will be disabled. - - You will be prompted for the GPG passphrase when the release build - starts, unless "gpg.passphrase" property is set. - - 2. If building the Windows installer - - If running the build in a UAC enabled environment, building the Windows - installer requires elevated privileges. The simplest way to do this is to - open the command prompt used for the build with the "Run as administrator" - option. - - 3. Configure the code signing service - - ASF committers performing official releases will need to configure the code - signing service so that the Windows installer is signed during the build - process. The following properties need to be added to the build.properties - file: - - # Location of GPG executable (used only for releases) - # Code signing of Windows installer - do.codesigning=true - codesigning.user=request-via-pmc - codesigning.pwd=request-via-pmc - codesigning.partnercode=request-via-pmc - codesigning.service=Microsoft Windows Signing - - Release managers will be provided with the necessary credentials by the PMC. - - 4. Build the release: - - cd ${tomcat.source} - ant release - - -(7) Tests - -(7.1) Running Tomcat tests - -Tomcat includes a number of junit tests. The tests are not run when a -release is built. There is separate command to run them. - -To run the testsuite use the following command: - - cd ${tomcat.source} - ant test - -It is advisable to redirect output of the above command to a file for later -inspection. - -The JUnit reports generated by the tests will be written to the following -directory: - - output/build/logs - -By default the testsuite is run three times to test 3 different -implementations of Tomcat connectors: NIO, NIO2 and APR. (If you are not -familiar with Tomcat connectors, see config/http.html in documentation for -details). - -The 3 runs are enabled and disabled individually by the following -properties, which all are "true" by default: - - execute.test.nio=true - execute.test.nio2=true - execute.test.apr=true - -The APR connector can be tested only if Tomcat-Native library binaries are -found by the testsuite. The "test.apr.loc" property specifies the directory -where the library binaries are located. - -By default the "test.apr.loc" property specifies the following location: - - output/build/bin/native/ - -If you are on Windows and want to test the APR connector you can put the -tcnative-1.dll file into ${tomcat.source}/bin/native/ and it will be copied -into the above directory when the build runs. - -The unit tests include tests of the clustering functionality which require -multicast to be enabled. There is a simple application provided in the Tomcat -test source (org.apache.catalina.tribes.TesterMulticast) that can be used to -check if a machine supports multicast. Notes on enabling multicast for different -operating systems are provided in the Javadoc for that class. - - -(7.2) Running a single test - -It is possible to run a single JUnit test class by adding the "test.entry" -property to the build.properties file. The property specifies the name of -the test class. - -For example: - - test.entry=org.apache.catalina.util.TestServerInfo - -It is possible to further limit such run to a number of selected test -methods by adding "test.entry.methods" property. The property specifies a -comma-separated list of test case methods. - -For example: - - test.entry=org.apache.el.lang.TestELArithmetic - test.entry.methods=testMultiply01,testMultiply02 - - -(7.3) Running a set of tests - -It is possible to run a set of JUnit test classes by adding the "test.name" -property to the build.properties file. The property specifies an Ant -includes pattern for the fileset of test class files to run. - -The default value is "**/Test*.java", so all test classes are being -executed (with few exceptions - see build.xml for several exclude patterns). - -You can include multiple patterns by concatenating them with a comma (",") -as the separator. - -For example: - - test.name=**/TestSsl.java,**/TestWebSocketFrameClientSSL.java - -You can exclude specific JUnit test classes by adding the "test.exclude" -property to the build.properties file. The property specifies an Ant -excludes pattern for the fileset of test class files to exclude form the run. -The default value is empty, so no classes are excluded. The syntax is the same -as for the property "test.name". - - -(7.4) Other configuration options - - 1. It is possible to configure the directory where JUnit reports are - written to. It is configured by "test.reports" property. The default - value is - - output/build/logs - - 2. It is possible to enable generation of access log file when the tests - are run. This is off by default and can be enabled by the following - property: - - test.accesslog=true - - The "access_log." file will be written to the same directory as - JUnit reports, - - output/build/logs - - 3. The testsuite respects logging configuration as configured by - ${tomcat.source}/conf/logging.properties - - The log files will be written to the temporary directory used by the - tests, - - output/test-tmp/logs - - 4. It is possible to configure formatter used by JUnit reports. - Configuration properties are "junit.formatter.type", - "junit.formatter.extension" and "junit.formatter.usefile". - - For example the following property disables generation of separate report - files: - - junit.formatter.usefile=false - - 5. It is possible to speed up testing by letting JUnit to run several - tests in parallel. - - This is configured by setting "test.threads" property. The recommended - value is one thread per core. - - 6. Optional support is provided for the Cobertura code coverage tool. - -NOTE: Cobertura is licensed under GPL v2 with parts of it being under - Apache License v1.1. See https://cobertura.github.io/cobertura/ for details. - Using it during Tomcat build is optional and is off by default. - - Cobertura can be enabled using the following properties: - - test.cobertura=true - test.threads=1 - - Using Cobertura currently requires setting test.threads configuration - property to the value of 1. Setting that property to a different value - will disable code coverage. - - The report files by default are written to - - output/coverage - - 7. The performance tests are written to run reasonably powerful machines (such - as a developer may use day to day) assuming no other resource hungry - processes are running. - - These assumptions are not always true (e.g. on CI systems running in a - virtual machine) so the performance tests may be disabled by using the - following property: - - test.excludePerformance=true - - 8. Some tests include checks that the access log valve entries are as expected. - These checks include timings. On slower / loaded systems these checks will - often fail. The checks may be relaxed by using the following property: - - test.relaxTiming=true - - 9. It is known that some platforms (e.g. OSX El Capitan) require IPv4 to - be the default for the multicast tests to work. This is configured by - the following property: - - java.net.preferIPv4Stack=true - - 10. It is possible to control whether the output of the tests is displayed - on the console or not. By default it is displayed and can be disabled - by the following property: - - test.verbose=true - -(8) Source code checks - -(8.1) Checkstyle - -NOTE: Checkstyle is licensed under LGPL. Using Checkstyle during Tomcat - build is optional and is off by default. - - See http://checkstyle.sourceforge.net/ for more information. - -Tomcat comes with a Checkstyle configuration that tests its source code -for certain conventions, like presence of the license header. - -To enable Checkstyle, add the following property to build.properties file: - - execute.validate=true - -Once Checkstyle is enabled, the check will be performed automatically -during the build. The check is run before compilation of the source code. - -To speed-up repeated runs of this check, a cache is configured. The cache -is located in the following directory: - - output/res/checkstyle - -It is possible to run the check separately by calling the "validate" -target. The command is: - - cd ${tomcat.source} - ant -Dexecute.validate=true validate - - -(8.2) FindBugs - -NOTE: FindBugs is licensed under LGPL. Using Findbugs during Tomcat build is - optional and is off by default. - - See http://findbugs.sourceforge.net/ for more information. - -To enable FindBugs, add the following property to build.properties file: - - execute.findbugs=true - -To compile Tomcat classes and generate a FindBugs report, call the -"findbugs" target. For example: - - cd ${tomcat.source} - ant -Dexecute.findbugs=true findbugs - -The report file by default is written to - - output/findbugs - - -(8.3) End-of-line conventions check - -You usually would not need to run this check. You can skip this section. - -Apache Tomcat project has convention that all of its textual source files, -stored in Subversion repository, are marked with Subversion property -"svn:eol-style" with value of "native". This convention makes the editing -of source code on different platforms easier. - -This test is used by developers to check that the source code adheres to -this convention. It verifies that the ends of lines in textual files are -appropriate for the operating system where it is run. The idea is to run -this check regularly on two different platforms and notify developers when -an inconsistency is detected. - -The command to run this test is: - - cd ${tomcat.source} - ant validate-eoln diff --git a/ZipProject/wwwroot/zip/15509330470/3/changelog.html b/ZipProject/wwwroot/zip/15509330470/3/changelog.html deleted file mode 100644 index 378ebd6..0000000 --- a/ZipProject/wwwroot/zip/15509330470/3/changelog.html +++ /dev/null @@ -1,5916 +0,0 @@ - -Apache Tomcat 9 (9.0.11) - Changelog

Overview

- -

Like many server applications, Tomcat installs a variety of class loaders -(that is, classes that implement java.lang.ClassLoader) to allow -different portions of the container, and the web applications running on the -container, to have access to different repositories of available classes and -resources. This mechanism is used to provide the functionality defined in the -Servlet Specification, version 2.4 — in particular, Sections 9.4 -and 9.6.

- -

In a Java environment, class loaders are -arranged in a parent-child tree. Normally, when a class loader is asked to -load a particular class or resource, it delegates the request to a parent -class loader first, and then looks in its own repositories only if the parent -class loader(s) cannot find the requested class or resource. Note, that the -model for web application class loaders differs slightly from this, -as discussed below, but the main principles are the same.

- -

When Tomcat is started, it creates a set of class loaders that are -organized into the following parent-child relationships, where the parent -class loader is above the child class loader:

- -

      Bootstrap
-          |
-       System
-          |
-       Common
-       /     \
-  Webapp1   Webapp2 ...

- -

The characteristics of each of these class loaders, including the source -of classes and resources that they make visible, are discussed in detail in -the following section.

- -

Class Loader Definitions

- -

As indicated in the diagram above, Tomcat creates the following class -loaders as it is initialized:

Bootstrap — This class loader contains the basic - runtime classes provided by the Java Virtual Machine, plus any classes from - JAR files present in the System Extensions directory - ($JAVA_HOME/jre/lib/ext). Note: some JVMs may - implement this as more than one class loader, or it may not be visible - (as a class loader) at all.
System — This class loader is normally initialized - from the contents of the CLASSPATH environment variable. All - such classes are visible to both Tomcat internal classes, and to web - applications. However, the standard Tomcat startup scripts - ($CATALINA_HOME/bin/catalina.sh or - %CATALINA_HOME%\bin\catalina.bat) totally ignore the contents - of the CLASSPATH environment variable itself, and instead - build the System class loader from the following repositories: -
-
- $CATALINA_HOME/bin/bootstrap.jar — Contains the - main() method that is used to initialize the Tomcat server, and the - class loader implementation classes it depends on.
- $CATALINA_BASE/bin/tomcat-juli.jar or - $CATALINA_HOME/bin/tomcat-juli.jar — Logging - implementation classes. These include enhancement classes to - java.util.logging API, known as Tomcat JULI, - and a package-renamed copy of Apache Commons Logging library - used internally by Tomcat. - See logging documentation for more - details.
  -
  If tomcat-juli.jar is present in - $CATALINA_BASE/bin, it is used instead of the one in - $CATALINA_HOME/bin. It is useful in certain logging - configurations
- $CATALINA_HOME/bin/commons-daemon.jar — The classes - from Apache Commons - Daemon project. - This JAR file is not present in the CLASSPATH built by - catalina.bat|.sh scripts, but is referenced - from the manifest file of bootstrap.jar.
-
Common — This class loader contains additional - classes that are made visible to both Tomcat internal classes and to all - web applications.
-
Normally, application classes should NOT - be placed here. The locations searched by this class loader are defined by - the common.loader property in - $CATALINA_BASE/conf/catalina.properties. The default setting will search the - following locations in the order they are listed:
-
- unpacked classes and resources in $CATALINA_BASE/lib
- JAR files in $CATALINA_BASE/lib
- unpacked classes and resources in $CATALINA_HOME/lib
- JAR files in $CATALINA_HOME/lib
-
By default, this includes the following:
-
- annotations-api.jar — JavaEE annotations classes.
- catalina.jar — Implementation of the Catalina servlet - container portion of Tomcat.
- catalina-ant.jar — Tomcat Catalina Ant tasks.
- catalina-ha.jar — High availability package.
- catalina-storeconfig.jar — Generation of XML - configuration files from current state
- catalina-tribes.jar — Group communication package.
- ecj-*.jar — Eclipse JDT Java compiler.
- el-api.jar — EL 3.0 API.
- jasper.jar — Tomcat Jasper JSP Compiler and Runtime.
- jasper-el.jar — Tomcat Jasper EL implementation.
- jsp-api.jar — JSP 2.3 API.
- servlet-api.jar — Servlet 4.0 API.
- tomcat-api.jar — Several interfaces defined by Tomcat.
- tomcat-coyote.jar — Tomcat connectors and utility classes.
- tomcat-dbcp.jar — Database connection pool - implementation based on package-renamed copy of Apache Commons Pool - and Apache Commons DBCP.
- tomcat-i18n-**.jar — Optional JARs containing resource bundles - for other languages. As default bundles are also included in each - individual JAR, they can be safely removed if no internationalization - of messages is needed.
- tomcat-jdbc.jar — An alternative database connection pool - implementation, known as Tomcat JDBC pool. See - documentation for more details.
- tomcat-util.jar — Common classes used by various components of - Apache Tomcat.
- tomcat-websocket.jar — WebSocket 1.1 implementation
- websocket-api.jar — WebSocket 1.1 API
WebappX — A class loader is created for each web - application that is deployed in a single Tomcat instance. All unpacked - classes and resources in the /WEB-INF/classes directory of - your web application, plus classes and resources in JAR files - under the /WEB-INF/lib directory of your web application, - are made visible to this web application, but not to other ones.

- -

As mentioned above, the web application class loader diverges from the -default Java delegation model (in accordance with the recommendations in the -Servlet Specification, version 2.4, section 9.7.2 Web Application Classloader). -When a request to load a -class from the web application's WebappX class loader is processed, -this class loader will look in the local repositories first, -instead of delegating before looking. There are exceptions. Classes which are -part of the JRE base classes cannot be overridden. There are some exceptions -such as the XML parser components which can be overridden using the appropriate -JVM feature which is the endorsed standards override feature for Java <= 8 -and the upgradeable modules feature for Java 9+. -Lastly, the web application class loader will always delegate first for JavaEE -API classes for the specifications implemented by Tomcat -(Servlet, JSP, EL, WebSocket). All other class loaders in Tomcat follow the -usual delegation pattern.

- -

Therefore, from the perspective of a web application, class or resource -loading looks in the following repositories, in this order:

Bootstrap classes of your JVM
/WEB-INF/classes of your web application
/WEB-INF/lib/*.jar of your web application
System class loader classes (described above)
Common class loader classes (described above)

- -

If the web application class loader is -configured with -<Loader delegate="true"/> -then the order becomes:

Bootstrap classes of your JVM
System class loader classes (described above)
Common class loader classes (described above)
/WEB-INF/classes of your web application
/WEB-INF/lib/*.jar of your web application

- -

XML Parsers and Java

- -

Starting with Java 1.4 a copy of JAXP APIs and an XML parser are packed -inside the JRE. This has impacts on applications that wish to use their own -XML parser.

- -

In old versions of Tomcat, you could simply replace the XML parser -in the Tomcat libraries directory to change the parser -used by all web applications. However, this technique will not be effective -when you are running modern versions of Java, because the usual class loader -delegation process will always choose the implementation inside the JDK in -preference to this one.

- -

Java <= 8 supports a mechanism called the "Endorsed Standards Override -Mechanism" to allow replacement of APIs created outside of the JCP -(i.e. DOM and SAX from W3C). It can also be used to update the XML parser -implementation. For more information, see: - -http://docs.oracle.com/javase/1.5.0/docs/guide/standards/index.html. For -Java 9+, use the upgradeable modules feature.

- -

Tomcat utilizes the endorsed mechanism by including the system property setting --Djava.endorsed.dirs=$JAVA_ENDORSED_DIRS in the -command line that starts the container. The default value of this option is -$CATALINA_HOME/endorsed. This endorsed directory is not -created by default. Note that the endorsed feature is no longer supported -with Java 9 and the above system property will only be set if either the -directory $CATALINA_HOME/endorsed exists, or the variable -JAVA_ENDORSED_DIRS has been set. -

- -

Note that overriding any JRE component carries risk. If the overriding -component does not provide a 100% compatible API (e.g. the API provided by -Xerces is not 100% compatible with the XML API provided by the JRE) then there -is a risk that Tomcat and/or the deployed application will experience errors.

- -

Running under a security manager

- -

When running under a security manager the locations from which classes -are permitted to be loaded will also depend on the contents of your policy -file. See Security Manager HOW-TO -for further information.

- -

Advanced configuration

- -

A more complex class loader hierarchy may also be configured. See the diagram -below. By default, the Server and Shared -class loaders are not defined and the simplifed hierarchy shown above is used. -This more complex hierarchy may be use by defining values for the -server.loader and/or shared.loader properties in -conf/catalina.properties.

- -


-  Bootstrap
-      |
-    System
-      |
-    Common
-     /  \
-Server  Shared
-         /  \
-   Webapp1  Webapp2 ...

- -

The Server class loader is only visible to Tomcat internals -and is completely invisible to web applications.

- -

The Shared class loader is visible to all web applications -and may be used to shared code across all web applications. However, any updates -to this shared code will require a Tomcat restart.

- -

For the impatient

- Simply add -

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>

- to your <Engine> or your <Host> element to enable clustering. -

- Using the above configuration will enable all-to-all session replication - using the DeltaManager to replicate session deltas. By all-to-all we mean that the session gets replicated to all the other - nodes in the cluster. This works great for smaller cluster but we don't recommend it for larger clusters(a lot of Tomcat nodes). - Also when using the delta manager it will replicate to all nodes, even nodes that don't have the application deployed.
- To get around this problem, you'll want to use the BackupManager. This manager only replicates the session data to one backup - node, and only to nodes that have the application deployed. Downside of the BackupManager: not quite as battle tested as the delta manager. -

- Here are some of the important default values: -

Multicast address is 228.0.0.4
Multicast port is 45564 (the port and the address together determine cluster membership.
The IP broadcasted is java.net.InetAddress.getLocalHost().getHostAddress() (make sure you don't broadcast 127.0.0.1, this is a common error)
The TCP port listening for replication messages is the first available server socket in range 4000-4100
Listener is configured ClusterSessionListener
Two interceptors are configured TcpFailureDetector and MessageDispatchInterceptor

The cluster implementation is written on the basis that a secure, trusted -network is used for all of the cluster related network traffic. It is not safe -to run a cluster on a insecure, untrusted network.

- -

There are many options for providing a secure, trusted network for use by a -Tomcat cluster. These include:

private LAN
a Virtual Private Network (VPN)
IPSEC

Cluster Basics

- -

To run session replication in your Tomcat 9 container, the following steps -should be completed:

All your session attributes must implement java.io.Serializable
Uncomment the Cluster element in server.xml
If you have defined custom cluster valves, make sure you have the ReplicationValve defined as well under the Cluster element in server.xml
If your Tomcat instances are running on the same machine, make sure the Receiver.port - attribute is unique for each instance, in most cases Tomcat is smart enough to resolve this on it's own by autodetecting available ports in the range 4000-4100
Make sure your web.xml has the - <distributable/> element
If you are using mod_jk, make sure that jvmRoute attribute is set at your Engine <Engine name="Catalina" jvmRoute="node01" > - and that the jvmRoute attribute value matches your worker name in workers.properties
Make sure that all nodes have the same time and sync with NTP service!
Make sure that your loadbalancer is configured for sticky session mode.

Load balancing can be achieved through many techniques, as seen in the -Load Balancing chapter.

Note: Remember that your session state is tracked by a cookie, so your URL must look the same from the out - side otherwise, a new session will be created.

The Cluster module uses the Tomcat JULI logging framework, so you can configure logging - through the regular logging.properties file. To track messages, you can enable logging on the key: org.apache.catalina.tribes.MESSAGES

Overview

- -

To enable session replication in Tomcat, three different paths can be followed to achieve the exact same thing:

Using session persistence, and saving the session to a shared file system (PersistenceManager + FileStore)
Using session persistence, and saving the session to a shared database (PersistenceManager + JDBCStore)
Using in-memory-replication, using the SimpleTcpCluster that ships with Tomcat (lib/catalina-tribes.jar + lib/catalina-ha.jar)

- -

In this release of session replication, Tomcat can perform an all-to-all replication of session state using the DeltaManager or - perform backup replication to only one node using the BackupManager. - The all-to-all replication is an algorithm that is only efficient when the clusters are small. For larger clusters, to use - a primary-secondary session replication where the session will only be stored at one backup server simply setup the BackupManager.
- Currently you can use the domain worker attribute (mod_jk > 1.2.8) to build cluster partitions - with the potential of having a more scalable cluster solution with the DeltaManager(you'll need to configure the domain interceptor for this). - In order to keep the network traffic down in an all-to-all environment, you can split your cluster - into smaller groups. This can be easily achieved by using different multicast addresses for the different groups. - A very simple setup would look like this: -

- -

        DNS Round Robin
-               |
-         Load Balancer
-          /           \
-      Cluster1      Cluster2
-      /     \        /     \
-  Tomcat1 Tomcat2  Tomcat3 Tomcat4

- -

What is important to mention here, is that session replication is only the beginning of clustering. - Another popular concept used to implement clusters is farming, i.e., you deploy your apps only to one - server, and the cluster will distribute the deployments across the entire cluster. - This is all capabilities that can go into with the FarmWarDeployer (s. cluster example at server.xml)

In the next section will go deeper into how session replication works and how to configure it.

- -

Cluster Information

Membership is established using multicast heartbeats. - Hence, if you wish to subdivide your clusters, you can do this by - changing the multicast IP address or port in the <Membership> element. -

- The heartbeat contains the IP address of the Tomcat node and the TCP port that - Tomcat listens to for replication traffic. All data communication happens over TCP. -

- The ReplicationValve is used to find out when the request has been completed and initiate the - replication, if any. Data is only replicated if the session has changed (by calling setAttribute or removeAttribute - on the session). -

- One of the most important performance considerations is the synchronous versus asynchronous replication. - In a synchronous replication mode the request doesn't return until the replicated session has been - sent over the wire and reinstantiated on all the other cluster nodes. - Synchronous vs. asynchronous is configured using the channelSendOptions - flag and is an integer value. The default value for the SimpleTcpCluster/DeltaManager combo is - 8, which is asynchronous. -

- For convenience, channelSendOptions can be set by name(s) rather than integer, - which are then translated to their integer value upon startup. The valid option names are: - "asynchronous" (alias "async"), "byte_message" (alias "byte"), "multicast", "secure", - "synchronized_ack" (alias "sync"), "udp", "use_ack". Use comma to separate multiple names, - e.g. pass "async, multicast" for the options - SEND_OPTIONS_ASYNCHRONOUS | SEND_OPTIONS_MULTICAST. -

- You can read more on the send flag(overview) or the - send flag(javadoc). - During async replication, the request is returned before the data has been replicated. async - replication yields shorter request times, and synchronous replication guarantees the session - to be replicated before the request returns. -

Bind session after crash to failover node

- If you are using mod_jk and not using sticky sessions or for some reasons sticky session don't - work, or you are simply failing over, the session id will need to be modified as it previously contained - the worker id of the previous tomcat (as defined by jvmRoute in the Engine element). - To solve this, we will use the JvmRouteBinderValve. -

- The JvmRouteBinderValve rewrites the session id to ensure that the next request will remain sticky - (and not fall back to go to random nodes since the worker is no longer available) after a fail over. - The valve rewrites the JSESSIONID value in the cookie with the same name. - Not having this valve in place, will make it harder to ensure stickiness in case of a failure for the mod_jk module. -

- Remember, if you are adding your own valves in server.xml then the defaults are no longer valid, - make sure that you add in all the appropriate valves as defined by the default. -

- Hint:
- With attribute sessionIdAttribute you can change the request attribute name that included the old session id. - Default attribute name is org.apache.catalina.ha.session.JvmRouteOrignalSessionID. -

- Trick:
- You can enable this mod_jk turnover mode via JMX before you drop a node to all backup nodes! - Set enable true on all JvmRouteBinderValve backups, disable worker at mod_jk - and then drop node and restart it! Then enable mod_jk Worker and disable JvmRouteBinderValves again. - This use case means that only requested session are migrated. -

For more info, Please visit the reference documentation -

          <Manager className="org.apache.catalina.ha.session.BackupManager"

-          -->

- This is a template for the manager configuration that will be used if no manager is defined in the <Context> - element. In Tomcat 5.x each webapp marked distributable had to use the same manager, this is no longer the case - since Tomcat you can define a manager class for each webapp, so that you can mix managers in your cluster. - Obviously the managers on one node's application has to correspond with the same manager on the same application on the other node. - If no manager has been specified for the webapp, and the webapp is marked <distributable/> Tomcat will take this manager configuration - and create a manager instance cloning this configuration. -
For more info, Please visit the reference documentation -

          <Channel className="org.apache.catalina.tribes.group.GroupChannel">

- The channel element is Tribes, the group communication framework - used inside Tomcat. This element encapsulates everything that has to do with communication and membership logic. -
For more info, Please visit the reference documentation -

            <Membership className="org.apache.catalina.tribes.membership.McastService"
-                        address="228.0.0.4"
-                        port="45564"
-                        frequency="500"
-                        dropTime="3000"/>

- Membership is done using multicasting. Please note that Tribes also supports static memberships using the - StaticMembershipInterceptor if you want to extend your membership to points beyond multicasting. - The address attribute is the multicast address used and the port is the multicast port. These two together - create the cluster separation. If you want a QA cluster and a production cluster, the easiest config is to - have the QA cluster be on a separate multicast address/port combination than the production cluster.
- The membership component broadcasts TCP address/port of itself to the other nodes so that communication between - nodes can be done over TCP. Please note that the address being broadcasted is the one of the - Receiver.address attribute. -
For more info, Please visit the reference documentation -

            <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
-                      address="auto"

-                      selectorTimeout="100"
-                      maxThreads="6"/>

- In tribes the logic of sending and receiving data has been broken into two functional components. The Receiver, as the name suggests - is responsible for receiving messages. Since the Tribes stack is thread less, (a popular improvement now adopted by other frameworks as well), - there is a thread pool in this component that has a maxThreads and minThreads setting.
- The address attribute is the host address that will be broadcasted by the membership component to the other nodes. -

            <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">
-              <Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>
-            </Sender>

- The sender component, as the name indicates is responsible for sending messages to other nodes. - The sender has a shell component, the ReplicationTransmitter but the real stuff done is done in the - sub component, Transport. - Tribes support having a pool of senders, so that messages can be sent in parallel and if using the NIO sender, - you can send messages concurrently as well.
- Concurrently means one message to multiple senders at the same time and Parallel means multiple messages to multiple senders - at the same time. -

-            <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatchInterceptor"/>
-            <Interceptor className="org.apache.catalina.tribes.group.interceptors.ThroughputInterceptor"/>
-          </Channel>

- Tribes uses a stack to send messages through. Each element in the stack is called an interceptor, and works much like the valves do - in the Tomcat servlet container. - Using interceptors, logic can be broken into more manageable pieces of code. The interceptors configured above are:
- TcpFailureDetector - verifies crashed members through TCP, if multicast packets get dropped, this interceptor protects against false positives, - ie the node marked as crashed even though it still is alive and running.
- MessageDispatchInterceptor - dispatches messages to a thread (thread pool) to send message asynchronously.
- ThroughputInterceptor - prints out simple stats on message traffic.
- Please note that the order of interceptors is important. The way they are defined in server.xml is the way they are represented in the - channel stack. Think of it as a linked list, with the head being the first most interceptor and the tail the last. -

-                 filter=".*\.gif|.*\.js|.*\.jpeg|.*\.jpg|.*\.png|.*\.htm|.*\.html|.*\.css|.*\.txt"/>

- The cluster uses valves to track requests to web applications, we've mentioned the ReplicationValve and the JvmRouteBinderValve above. - The <Cluster> element itself is not part of the pipeline in Tomcat, instead the cluster adds the valve to its parent container. - If the <Cluster> elements is configured in the <Engine> element, the valves get added to the engine and so on. -
For more info, Please visit the reference documentation -

          <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
-                    tempDir="/tmp/war-temp/"
-                    deployDir="/tmp/war-deploy/"
-                    watchDir="/tmp/war-listen/"
-                    watchEnabled="false"/>

- The default tomcat cluster supports farmed deployment, ie, the cluster can deploy and undeploy applications on the other nodes. - The state of this component is currently in flux but will be addressed soon. There was a change in the deployment algorithm - between Tomcat 5.0 and 5.5 and at that point, the logic of this component changed to where the deploy dir has to match the - webapps directory. -
For more info, Please visit the reference documentation -

          <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>
-        </Cluster>

- Since the SimpleTcpCluster itself is a sender and receiver of the Channel object, components can register themselves as listeners to - the SimpleTcpCluster. The listener above ClusterSessionListener listens for DeltaManager replication messages - and applies the deltas to the manager that in turn applies it to the session. -

How it Works

To make it easy to understand how clustering works, We are gonna take you through a series of scenarios. - In the scenario we only plan to use two tomcat instances TomcatA and TomcatB. - We will cover the following sequence of events:

- -

TomcatA starts up
TomcatB starts up (Wait that TomcatA start is complete)
TomcatA receives a request, a session S1 is created.
TomcatA crashes
TomcatB receives a request for session S1
TomcatA starts up
TomcatA receives a request, invalidate is called on the session (S1)
TomcatB receives a request, for a new session (S2)
TomcatA The session S2 expires due to inactivity.

- -

Ok, now that we have a good sequence, we will take you through exactly what happens in the session replication code

- -

TomcatA starts up -
- Tomcat starts up using the standard start up sequence. When the Host object is created, a cluster object is associated with it. - When the contexts are parsed, if the distributable element is in place in web.xml - Tomcat asks the Cluster class (in this case SimpleTcpCluster) to create a manager - for the replicated context. So with clustering enabled, distributable set in web.xml - Tomcat will create a DeltaManager for that context instead of a StandardManager. - The cluster class will start up a membership service (multicast) and a replication service (tcp unicast). - More on the architecture further down in this document. -
-
TomcatB starts up -
- When TomcatB starts up, it follows the same sequence as TomcatA did with one exception. - The cluster is started and will establish a membership (TomcatA,TomcatB). - TomcatB will now request the session state from a server that already exists in the cluster, - in this case TomcatA. TomcatA responds to the request, and before TomcatB starts listening - for HTTP requests, the state has been transferred from TomcatA to TomcatB. - In case TomcatA doesn't respond, TomcatB will time out after 60 seconds, and issue a log - entry. The session state gets transferred for each web application that has distributable in - its web.xml. Note: To use session replication efficiently, all your tomcat instances should be - configured the same. -
-
TomcatA receives a request, a session S1 is created. -
- The request coming in to TomcatA is treated exactly the same way as without session replication. - The action happens when the request is completed, the ReplicationValve will intercept - the request before the response is returned to the user. - At this point it finds that the session has been modified, and it uses TCP to replicate the - session to TomcatB. Once the serialized data has been handed off to the operating systems TCP logic, - the request returns to the user, back through the valve pipeline. - For each request the entire session is replicated, this allows code that modifies attributes - in the session without calling setAttribute or removeAttribute to be replicated. - a useDirtyFlag configuration parameter can be used to optimize the number of times - a session is replicated. -
- -
TomcatA crashes -
- When TomcatA crashes, TomcatB receives a notification that TomcatA has dropped out - of the cluster. TomcatB removes TomcatA from its membership list, and TomcatA will no longer - be notified of any changes that occurs in TomcatB. - The load balancer will redirect the requests from TomcatA to TomcatB and all the sessions - are current. -
-
TomcatB receives a request for session S1 -
Nothing exciting, TomcatB will process the request as any other request. -
-
TomcatA starts up -
Upon start up, before TomcatA starts taking new request and making itself - available to it will follow the start up sequence described above 1) 2). - It will join the cluster, contact TomcatB for the current state of all the sessions. - And once it receives the session state, it finishes loading and opens its HTTP/mod_jk ports. - So no requests will make it to TomcatA until it has received the session state from TomcatB. -
-
TomcatA receives a request, invalidate is called on the session (S1) -
The invalidate call is intercepted, and the session is queued with invalidated sessions. - When the request is complete, instead of sending out the session that has changed, it sends out - an "expire" message to TomcatB and TomcatB will invalidate the session as well. -
- -
TomcatB receives a request, for a new session (S2) -
Same scenario as in step 3) -
- - -
TomcatA The session S2 expires due to inactivity. -
The invalidate call is intercepted the same was as when a session is invalidated by the user, - and the session is queued with invalidated sessions. - At this point, the invalidated session will not be replicated across until - another request comes through the system and checks the invalid queue. -
-

- -

Phuuuhh! :)

- -

Membership - Clustering membership is established using very simple multicast pings. - Each Tomcat instance will periodically send out a multicast ping, - in the ping message the instance will broad cast its IP and TCP listen port - for replication. - If an instance has not received such a ping within a given timeframe, the - member is considered dead. Very simple, and very effective! - Of course, you need to enable multicasting on your system. -

- -

TCP Replication - Once a multicast ping has been received, the member is added to the cluster - Upon the next replication request, the sending instance will use the host and - port info and establish a TCP socket. Using this socket it sends over the serialized data. - The reason I choose TCP sockets is because it has built in flow control and guaranteed delivery. - So I know, when I send some data, it will make it there :) -

- -

Distributed locking and pages using frames - Tomcat does not keep session instances in sync across the cluster. - The implementation of such logic would be to much overhead and cause all - kinds of problems. If your client accesses the same session - simultaneously using multiple requests, then the last request - will override the other sessions in the cluster. -

- -

Monitoring your Cluster with JMX

Monitoring is a very important question when you use a cluster. Some of the cluster objects are JMX MBeans

Add the following parameter to your startup script with Java 5:

set CATALINA_OPTS=\
--Dcom.sun.management.jmxremote \
--Dcom.sun.management.jmxremote.port=%my.jmx.port% \
--Dcom.sun.management.jmxremote.ssl=false \
--Dcom.sun.management.jmxremote.authenticate=false

Connectors How To

Introduction
HTTP
AJP

Introduction

- -

Choosing a connector to use with Tomcat can be difficult. This page will -list the connectors which are supported with this Tomcat release, and will -hopefully help you make the right choice according to your needs.

- -

HTTP

- -

The HTTP connector is setup by default with Tomcat, and is ready to use. This -connector features the lowest latency and best overall performance.

- -

For clustering, a HTTP load balancer with support for web sessions stickiness -must be installed to direct the traffic to the Tomcat servers. Tomcat supports mod_proxy -(on Apache HTTP Server 2.x, and included by default in Apache HTTP Server 2.2) as the load balancer. -It should be noted that the performance of HTTP proxying is usually lower than the -performance of AJP, so AJP clustering is often preferable.

- -

AJP

- -

When using a single server, the performance when using a native webserver in -front of the Tomcat instance is most of the time significantly worse than a -standalone Tomcat with its default HTTP connector, even if a large part of the web -application is made of static files. If integration with the native webserver is -needed for any reason, an AJP connector will provide faster performance than -proxied HTTP. AJP clustering is the most efficient from the Tomcat perspective. -It is otherwise functionally equivalent to HTTP clustering.

- -

The native connectors supported with this Tomcat release are:

JK 1.2.x with any of the supported servers
mod_proxy on Apache HTTP Server 2.x (included by default in Apache HTTP Server 2.2), -with AJP enabled

- -

Other native connectors supporting AJP may work, but are no longer supported.

Introduction

- -

Download a Java Development Kit (JDK) version 8

- -

-IMPORTANT: Set an environment variable JAVA_HOME to the pathname of the -directory into which you installed the JDK release. -

- -

Install Apache Ant 1.9.8 or later

- -

-Download a binary distribution of Ant 1.9.8 or later from -here. -

- -

Checkout or obtain the Tomcat source code

- -

- Tomcat SVN repository URL: - https://svn.apache.org/repos/asf/tomcat/trunk/ -

- Tomcat source packages: - https://tomcat.apache.org/download-90.cgi. -

- -

Configure download area

- -

- Building Tomcat involves downloading a number of libraries that it depends on. - It is strongly recommended to configure download area for those libraries. -

- -

- By default the build is configured to download the dependencies into the - ${user.home}/tomcat-build-libs directory. You can change this - (see below) but it must be an absolute path. -

- -

- The download area is defined by property base.path. For example: -

- -

# ----- Default Base Path for Dependent Packages -----
-# Replace this path with the directory path where
-# dependencies binaries should be downloaded.
-base.path=/home/me/some-place-to-download-to

- -

- Different versions of Tomcat are allowed to share the same download area. -

- -

- Another example: -

- -

base.path=${user.dir}/../libraries-tomcat9.0

- -

- Users who access the Internet through a proxy must use the properties - file to indicate to Ant the proxy configuration: -

- -

# ----- Proxy setup -----
-proxy.host=proxy.domain
-proxy.port=8080
-proxy.use=on

- -

Building Tomcat

- -

-Use the following commands to build Tomcat: -

- -

-cd ${tomcat.source}
-ant -

- -

Building with Eclipse

- -

-WARNING: Do not forget to create and configure - ${tomcat.source}/build.properties file as described above - before running any Ant targets. -

- -

-An Ant target is provided as a convenience to download all binary dependencies, and to create -the Eclipse project and classpath files in the root of the source tree. -

- -

-cd ${tomcat.source}
-ant ide-eclipse -

- -

-Start Eclipse and create a new Workspace. -

- -

-Open the Preferences dialog and then select Java->Build Path->Classpath -Variables to add two new Classpath Variables: -

- - - - - -

TOMCAT_LIBS_BASE	The same location as the `base.path` - setting in `build.properties`, where the binary dependencies have been downloaded
ANT_HOME	the base path of Ant 1.9.8 or later

- - -

-Use File->Import and choose Existing Projects into Workspace. -From there choose the root directory of the Tomcat source tree (${tomcat.source}) -and import the Tomcat project located there. -

- -

-Tweaking a few formatting preferences will make it much easier to keep consistent with Tomcat -coding conventions (and have your contributions accepted): -

- - - - - - - - -

Java -> Code Style -> Formatter -> Edit...	Tab policy: Spaces only Tab and Indentation size: 4
General -> Editors -> Text Editors	Displayed tab width: 2 Insert spaces for tabs Show whitespace characters (optional)
XML -> XML Files -> Editor	Indent using spaces Indentation size: 2
Ant -> Editor -> Formatter	Tab size: 2 Use tab character instead of spaces: unchecked

- -

-The recommended configuration of Compiler Warnings is documented in -res/ide-support/eclipse/java-compiler-errors-warnings.txt file. -

- -

Building with other IDEs

-The same general approach should work for most IDEs; it has been reported -to work in IntelliJ IDEA, for example. -
