EJB3.0 jar on JBOSS not deploying

[Russell Ray]

Guys:

Okay, I am following a simple tutorial of creating an entity and statless session beans. I am use JBoss 4.0.3SP1, JDK 1.5.06. I can compile and deploy using ant. There is no problems. However, launching the server has problems. I have no other projects running on the App Server other than this project. I have followed the instructions of readying the AS to run EJB3.0 standard projects using the follow instructions:

JBOSS Instructions


However, the server still complains about the project:

[19:40:01,859] [WARN ] [ServiceController] Ignoring request to stop nonexistent service: jboss.j2ee:service=EJB3,jar=EJB3Demo.jar,name=BookBean
[19:40:01,859] [WARN ] [ServiceController] Ignoring request to destroy nonexistent service: jboss.j2ee:service=EJB3,jar=EJB3Demo.jar,name=BookBean
[19:40:01,875] [WARN ] [ServiceController] Problem starting service jboss.j2ee:service=EJB3,module=EJB3Demo.jar
java.lang.RuntimeException: Field javax.persistence.EntityManager com.russ.library.BookBean.em @PersistenceUnit in error: EMPTY STRING unitName but there is no deployments in scope
at org.jboss.ejb3.injection.PersistenceContextHandler.loadFieldDependencies(PersistenceContextHandler.java:361)
at org.jboss.ejb3.injection.PersistenceContextHandler.loadDependencies(PersistenceContextHandler.java:413)

I have search the internet concerning the error, but no one has offered a solution to this type of error.

Any help would be greatly appreciated.

okay, I found the problem.

In the session bean I failed to prove the unit name.

@PersistenceContext(unitName="Ejb3Demo")
