I'm not an expert Java programmer, and neither a JBoss guru, so it's possible that I'm not using the right search keys. Plz be patient if my questions seems a little bit obvious :) I.E.: Wed Sep 6, 2006 http://www.jboss.com/index.html?module=bb&op=viewtopic&t=88410 It's so old and no solutions where proposed, maybe because it's the first occurrency of this problem.

You answered: "Realy ancient, and should not occur http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3951967#... .. but unfortunately the proposed solution doesn't seem to work for me.
