Hi
I have a little problem, because I have made the persistence and made the conecction to MySQL, but the console marks the next.
java.lang.RuntimeException: javax.management.InstanceAlreadyExistsException: persistence.units:jar=tutorialEstudiante.jar,unitName=Estudiante already registered.
20:36:58,211 INFO [EJB3Deployer] Deployed: file:/Applications/jboss/server/default/deploy/tutorialEstudiante.jar

State: FAILED
Reason: java.lang.RuntimeException: javax.management.InstanceAlreadyExistsException: persistence.units:jar=tutorialEstudiante.jar,unitName=Estudiante already registered.
The curious is that the Beans are stored in memory by the stateful, but when I try to the the database the table and the Beans doesn't appear.
Thanks.
