Sorry for my bad english, i'm from Spain.
I just want to explain my experience running the registration example, to help to futures partners..
When i inserted the name and the pass and then i clicked "register" i got an error HTTP 500, i broke my head searching for the solution, and then i found there was a problem qith the version of the JBoss Installer, so if some of you have that problem, try uninstalling the JBoss and installing it again with de JEMs installer, here you have the link:

Well i hope it work!
