You can find the code here:
http://anonsvn.jboss.org/repos/jbossprofiler/branches/JBossProfiler2
I'm working on some improvements for the Beta6 release, so it is a bit of a mess currently.
There is no web application yet for the profiler - I'm looking for contributors who are interested in that area to do the work. So if you like doing web app development feel free to join the project !
