Phew! So sorry... but I solved the problem!!! The replacement wasn't functioning because, for some reason, I had to shutdown JBoss AS! When I runned the server again, the arg0 was found... Well... but it's so strange, do I really need to replace everything?!? I'll do this, but if anyone knows how to use the names generated by wstools, please tell me! ^^ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4067646#...
