Yeah dude I'm having the same problem and it's really pissing me off!! I load my CMP from a servlet, and it gets the all the information from the database just fine, but when the execution stops, it has deleted the row from the database!!
DOES ANYBODY KNOW THE CURE!! DEAR GOD I NEED A CURE!
I just installed almost the exact configuration, just with a little bit older version of mySQL. I haven't editted much in way of config files, but I get the exact same problem. I'm not sure if this is a bug of jboss or what I'm missing here, but it seems like a couple people are having the same problems out of the box.
Too bad my only responses have been from people with the same problem.
nevermind figured out it was my own stupidity from following an out of date tutorial
