Sounds promising. I mailed Tim a test which reproduces the behaviour, but was intermittent at the time. I've just done 2 clean installs: 1 of 4.2.0/1.3.0GA, and consistently got that error when creating a connection, I then did a clean 4.2.0/1.4.0CR2 install, and didn't see the error. However, I have seen the code work sometimes on 1.3.0GA, and sometimes fail, so you'll forgive me if I don't hold my breath? I'll mail you the test, I believe Tim is on holiday for a while? Can you expand on what the problem/resolution was? I've been tearing my hair out on this. Thanks Clebert, Best regards, Bob View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4081740#...
