I have deleted the original Mysql Driver files and configurations and regenerated them. I am getting the same results. If anyone has any suggestions please let me know. If someone has a link to some documentyation for configuring Hibernate in Jboss developer studio that they found helpful it would be greatly appreciated. I haven't found much documentation.
