      <title>Building Tomcat


<section name="Introduction">

Building Apache Tomcat from SVN is very easy, and is the first step to contributing to
Tomcat. The following is a step by step TODO list.


<section name="Download a Java Development Kit (JDK) release (version 1.5.x or later)">

The Sun JDK can be downloaded <a href="">here.

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


<section name="Install Apache Ant 1.6.5 or later">

Download a binary distribution of Ant 1.6.5 or later from 
<a href="">here.

Unpack the binary distribution into a convenient location so that the
Ant release resides in its own directory (conventionally named
"apache-ant-1.6.x").  For the purposes of the remainder of this document,
the symbolic name "${ant.home}" is used to refer to the full pathname of
 the release directory.

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.


<section name="Checkout or obtain the source code for Tomcat 6.0">

  Tomcat SVN repository URL:
  Download a source package from:
  Checkout the source using SVN, selecting the desired version or
  branch (current development source is at 
  <code>, or 
  unpack the source package. The location where the source has been
  placed will be referred as ${tomcat.source}.


<section name="Building Tomcat">

Use the following commands:
cd ${tomcat.source}<br/> ant download<br/> ant<br/> </code> </p> <p> NOTE: Users accessing the Internet through a proxy must use a properties file to indicate to Ant the proxy configuration. Read below. </p> <p> WARNING: Running this command will download binaries to the <code>/usr/share/java directory. Make sure this is appropriate to do so on your computer. On Windows, this usually corresponds to the <code>C:\usr\share\java directory, unless Cygwin is used. Read below to customize the directory used to download the binaries. </p> <p> The build can be controlled by creating a ${tomcat.source}/ file, and adding the following content to it: <code>
# ----- Proxy setup -----<br/> # Uncomment if using a proxy server.<br/><br/> #proxy.port=8080<br/> #proxy.use=on<br/> <br/> # ----- Default Base Path for Dependent Packages -----<br/> # Replace this path with the directory path where<br/> # dependencies binaries should be downloaded.<br/> base.path=/usr/share/java<br/> </code> </p> </section> <section name="Building with Eclipse"> <p> <b>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. </p> <p> Note that you <b>must complete all the above steps to fetch the repositories and build some JAR files the first time. After you have completed the above steps, you can set up a series of Eclipse 4 projects. <b>Note that 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. </p> <p> Use Windows->Preferences and then Java->Build Path->Classpath Variables to add two new Classpath variables: </p> <p> <table border="1"> <tr>
