Does anyone have any idea what this error means? I have been trying to figure it out but haven't made any progress. I am deploying only the files shown below (in snippets) as a jar file to jboss. Thanks in advance. - - Flight class - - | @Entity | public class Flight implements Serializable { | ... | @Id (above my primary key) | ... | - - FlightBean code - - | @Stateless | public class FlightBean implements IFlight{ | @PersistenceContext (unitName="tps") | protected EntityManager em; | ... | - - IFlight - - | @Remote | public interface IFlight { | ... | - - Persistence.xml - - | <persistence> | <persistence-unit name="ejb3trail"> | <jta-data-source>java:/DefaultDS</jta-data-source> | <properties> | <property name="hibernate.hbm2ddl.auto" | value="create-drop"/> | </properties> | </persistence-unit> | </persistence> | Error Message | 17:30:01,593 INFO [JmxKernelAbstraction] creating wrapper delegate for: org.jbo | ss.ejb3.stateless.StatelessContainer | 17:30:01,593 INFO [JmxKernelAbstraction] installing MBean: jboss.j2ee:jar=tps-e | ntity.jar,name=FlightBean,service=EJB3 with dependencies: | 17:30:01,593 INFO [JmxKernelAbstraction] persistence.units:unitName=tps | 17:30:01,593 INFO [EJB3Deployer] Deployed: file:/C:/jboss-4.2.2.GA/server/defau | lt/deploy/tps-entity.jar | 17:30:01,609 ERROR [URLDeploymentScanner] Incomplete Deployment listing: | | --- MBeans waiting for other MBeans --- | ObjectName: jboss.j2ee:jar=tps-entity.jar,name=FlightBean,service=EJB3 | State: NOTYETINSTALLED | I Depend On: | persistence.units:unitName=tps | | --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM --- | ObjectName: persistence.units:unitName=tps | State: NOTYETINSTALLED | Depends On Me: | jboss.j2ee:jar=tps-entity.jar,name=FlightBean,service=EJB3 | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4139946#...
