is it good idea to add JAVA_OPTS to environment variables.., but i'm still confused how Jboss didn't work on run.conf? — user763958, May 21 '11 at 13:42

You can check if you have run.conf file in the your configuration directory (default or maybe production).

At least in JBoss EAP 4.3 each profile can have own running configuration file. If you find such file you have to edit -XX:MaxPermSize parameter.

You need to make sure your JBoss instance is properly configured to handle PermGen. I don't know why the default configs don't come with this stuff in them; for some reason you need to just magically know this stuff. Here's a link on how to configure: http://blog.dahanne.net/2009/08/12/jboss-and-java-lang-outofmemoryerror-permgen-space/.
