Introduction
	Java Servlets and JSPs are made available on the Virtual Server via Tomcat, the flagship product of the Apache Jakarta Project. Tomcat is a world-class implementation of the Java Servlet 2.2 and Java Server Pages 1.1 Specifications.
	Installation
	Do the following, according to your Virtual Server O/S. FreeBSD Tomcat is unavailable. Try mod_jserv. Solaris Tomcat 3.2.3 Connect to your Virtual Server via Telnet or SSH and follow these instructions: Install Java (JDK 2). Install the Jakarta Tomcat Server. Run this command: % vinstall tomcat This is the Java Servlet engine. It knows how to parse JavaServer pages, Java Servlets, and other kinds of things. It runs a web server on port 8080 and has a special jserv-type protocol listening on 8007. It also has an enhanced and improved protocol listening on 8009, which is what mod_jk Apache Module talks to it on. The mod_jserv Apache Module talks on 8007. Start Tomcat. Use this command: % virtual /usr/local/jakarta/jakarta-tomcat/bin/startup.sh Install the mod_jk Apache Module
	Configuration
	The Tomcat installation includes online admin pages that can be accessed at this URL: http://YOUR-DOMAIN.NAME/admin/contextAdmin/contextAdmin.html In order to set up a user name and password for these online admin pages, complete the following steps. Change the admin context to "true". Open the ~/usr/local/jakarta/jakarta-tomcat-3.2.1/conf/server.xml file and look for the following entry: <!-- Admin context will use tomcat.core to add/remove/get info about the webapplications and tomcat internals. By default it is not trusted - i.e. it is not allowed access to tomcat internals, only informations that are available to all servlets are visible. If you change this to true, make sure you set a password. --> <Context path="/admin" docBase="webapps/admin" crossContext="true" debug="0" reloadable="true" trusted="false" > </Context> You need to change the field trusted="false" to trusted="true". Open the ~/usr/local/jakarta/jakarta-tomcat-3.2.1/conf/tomcat-users.xml file and add a user with roles set to admin. An example would be as follows: <user name="johnny" password="cash" roles="admin" /> The name and password fields can be whatever you want but the roles need to include admin, though there can be additional comma separated roles. Restart Tomcat. Use these commands: % kill PID % virtual /usr/local/jakarta/jakarta-tomcat/bin/startup.sh
