RESTEasy with JBOSS

OK, just to see what's happening, extract your war file into the jboss directory, rather than have it do it for you.
(This assumes you haven't done this).
Then look in the WEB-INF/lib directory and show us here all the libs you have in there.

Also, once you have all the correct libs and it is still not working, then post any exceptions here.

Always check your logs when something goes wrong.
Do not expect one fix to make things work.

My problem is bad version.
The RESTEasy is is compiled with JDK 1.6 but I need run with JDK 1.5
