[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - java.lang.RuntimeException: javax.management.InstanceAlready

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 20:36:58,228 ERROR [URLDeploymentScanner] Incomplete Deployment listing: --- MBeans waiting for other MBeans --- ObjectName: persistence.units:jar=tutorialEstudiante.jar,unitName=Estudiante State: NOTYETINSTALLED I Depend On: jboss.jca:name=MySQLDS,service=ManagedConnectionFactory ObjectName: jboss.j2ee:service=EJB3,module=tutorialEstudiante.jar State: FAILED Reason: java.lang.RuntimeException: javax.management.InstanceAlreadyExistsException: persistence.units:jar=tutorialEstudiante.jar,unitName=Estudiante already registered. --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM --- ObjectName: jboss.jca:name=MySQLDS,service=ManagedConnectionFactory State: NOTYETINSTALLED Depends On Me: persistence.units:jar=tutorialEstudiante.jar,unitName=Estudiante ObjectName: jboss.j2ee:service=EJB3,module=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.
