I'm going to try to make it easy for everyone to help out with +the documentation of Tomcat, more specifically the documentation for the +connectors. This is written from a windows user perspective as I believe they +will most benefit from it. For people using Unix it should be easy for them to +apply these steps. Just substitute Unix syntax where needed. +</p> +<p> + The documentation is produced using xml with xsl style sheets. This +effectivly seperates the content of the documents from the style, so all that +contributers need to worry about the content. It is much easier to use than +html. +</p> +<p> + It's all really quite simple. Here is what you will need: +<ul> +<li> +<b>A recent version of Ant</b> +</li> +<li> +<b>The source code for the connectors from subversion</b> +</li> +<li> +<b>Any ascii text editor</b> +</li> +</ul> +</p> +</section> +<section name="Getting Started Step by Step"> +<p> + After you get these tools they are simple to set up. +</p> + <subsection name="STEP 1. Get Ant"> +<p> + Install <a href="http://ant.apache.org/">Ant</a>. The only advice I +have is to choose a simple installation path. Now set an environment variable +for ANT_HOME, and then add the location of the Ant/bin directory to your PATH +variable. Consult your Operating system documentation for information on how +to do this. When you are finished verify that you can run ant from the command +line. +</p> +<p> + Ant is used to build the documentation, among other things, and it must be +able to see a file called <b>build.xml</b>. This file is located in the +<b>xdocs</b> directory. In the +<b>build.xml</b> file there is a target named <b>all</b> that will be used to build +the docs. +</p> +</subsection> +<subsection name="STEP 2. Get the sources"> +<p> + Get the sources for +<a href="http://svn.apache.org/repos/asf/tomcat/jk/trunk/">tomcat-connectors</a> +from the subversion repository. If you'll +be editing from a windows platform you will need a windows subversion client. There +are several available. I like <a href="http://tortoisesvn.tigris.org/">turtoiseSVN</a>. +Unix users should install the subversion client of their choice, +if they don't already have one. +</p> +<p> + You are ready to download the sources now. Change directory to the +location where you want your repository to be. For simplicity we will call this +your <b>SVN_HOME</b>. Mine is located in C:\build. +</p> +<p> + Run the following command to <b>checkout</b> the sources for the first time. +You should only need to do this once. +<screen> +<read> </read> +<read>C:\build\>svn checkout http://svn.apache.org/repos/asf/tomcat/jk/trunk/ +tomcat-connectors</read> +<read> </read> +</screen> +</p> +<p> + You should now be watching all the downloads come in. Now that you have +the sources on your machine the hard part is over. From now on, to update your +sources all you have to do is cd into any directory in your repository and run +the <b>svn update</b> command. + <screen> +<note> To update your xdocs directory simply cd into the xdocs directory +and:</note> +<read>C:\build\tomcat-connectors\>cd xdocs</read> +<read>C:\build\tomcat-connectors\xdocs\>svn update</read> +</screen> +</p> +</subsection> +<subsection name="STEP 3. Test your build environment"> +<p> + Open a command prompt window and cd to the directory where you downloaded +the source.
