I tried replying to above link this yesterday and got an 'Error posting' and did not try again. Now I see it was on a completely wrong server (JBoss probably had some maintanance) Sorry diwaker for my response in the private mail, but even worse, you posted this yesterday and send me a *private* mail today, come on. Give everybody some time to respond. And if it is realy urgent, again I suggest buying commercial support from anybody but preferably JBoss ;-) (although I do not even work for them)
Now with regard to the problem.
The thing is that the error here contains to little info. Look at the stacktrace in the logging to see if it contains more info and post it here if it does not mean anything to you
