EJB3 stateless session bean not deploying correctly

[perfectionist]

I am using jboss 4.0.3RC1 with EJB3 support in all deployment.

I have defined a stateless entity bean using JbossIDE 1.5M2

When deploying the ear file I get this message for the stateless session bean in the log.

...
23:06:30,100 WARN [ServiceController] Problem starting service jboss.j2ee:service=EJB3,name=com.oreilly.jbossnotebook.todo.ejb3.TaskMasterBean
java.lang.NullPointerException: factory must not be null
 at org.jboss.ejb3.entity.InjectedEntityManager.<init>(InjectedEntityManager.java:40)

 at org.jboss.ejb3.injection.PersistenceContextHandler.loadFieldInjectors(PersistenceContextHandler.java:158)
 at org.jboss.ejb3.injection.PersistenceContextHandler.loadInjectors(PersistenceContextHandler.java:127)

The bean looks like

public @Stateless class TaskMasterBean implements TaskMaster {

 @PersistenceContext
 protected EntityManager manager;
...
}

Just what does factory must not be null

This turned out to be a problem with the configuration xml files. When I narrow the exact cause down I will post.

Hi,

Did you name your entitymanager in your persistence.xml?:

<entity-manager>
 <name>manager1</name>
 ...
</entity-manager>

In that case you need to put untName on the Injection:

@PersistenceContext (unitName = "manager1")
private EntityManager manager1;

(see getManagedEntityManagerFactory in org.jboss.ejb3.injection.PersistenceContextHandler)

Cheers,
