Finding an Issue tracking system

To the extent of my knowledge, we are only able to run java based applications on the server. That means we have to find a issue tracking system that runs under Tomcat.

We could start by evaluating this:

http://scarab.tigris.org/ - Scarab, from the sponsors of Subversion


I know also:

Mantis (runs under apache and needs PHP and Mysql)
Bugzilla (runs under apache and needs Perl and MySQL)

Arthur pointed me Xplanner, that is built specifically to manage XP projects:
