Cheers everyone, I have a small problem. After I deploy several times my project on the server, I get an error that sais something about the fact that PermGen is out of memory. Can anyone explain very shortly why does this happen and what can I do to not get this kind of behavior(because I hate restarting the jboss server everytime I get this error).
