It doesn't matter if your client is running in eclipse or anywhere else, it still needs to be using the correct jars. I was merely pointing out that those correct jars are specified in the user guide. It seems that previously you were using different jars than those specified in the user guide, but now you are using the correct ones, so all is good :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4055437#...
