I decided I need to learn some JSP to get back in the JAVA game.
Just for stability and old school cool, I'm using Debian Lenny and the Tomcat that it installs.
You can apt-get install tomcat5.5 and tomcat5.5-admin and tomcat5.5-webapps to get everything you need.
It installs struts 1.2 by default so you don't have to go looking.
The Tomcat Default folder is /usr/share/tomcat5.5/
