Thanks very much, 4.0.4c was a jboss version I got when I installed jbpm, it was part of the starters kit, I was not aware that it was not a release or tag. However, it is the same behaviour on the JBOSS 4.0.4 GA. RetrieveConnection() is being used in servlets, so I will turn it on for servlets and also turn trace onb in log4j.xml. Also, you are correct it is not JNDI Pooling, I meant the JCA Connection pool. Thanks very much for the help. Kazam.
