I'm having problems using standard dependency injection in a @MessageDriven bean.
This is the code:
@MessageDriven(........)
public class FooQueueListener implements MessageListener
{
@PersistenceContext
private EntityManager mEntityManager;
@EJB(mappedName = "foo/ejb/FooBean")
private Foo mFoo;
public void onMessage(Message message)
{
// Problem: mFoo is always null
}
}
When onMessage() is executed, mFoo is always null. I can see with twiddle that foo/ejb/FooBean really exists in the Global JNDI namespace though, and looking it up manually works fine:
public void onMessage(Message message)
{
InitialContext initialContext = new InitialContext();
mFoo = (Foo) initialContext.lookup("foo/ejb/FooBean");
mFoo.blah();
}
It doesn't work in the following cases.
Simple DI without any naming changes:
@Local
public interface Foo {
void blah();
}
@Stateful
public class FooBean implements Foo {
void Blah() {}
}
@MessageDriven(........)
public class FooQueueListener implements MessageListener
{
@EJB
private Foo mFoo;
}
Or with a LocalBinding:
@Local
public interface Foo {
void blah();
}
@Stateful @LocalBinding(jndiName="foo/ejb/FooBean")
public class FooBean implements Foo {
void Blah() {}
}
@MessageDriven(........)
public class FooQueueListener implements MessageListener
{
@EJB(mappedName = "foo/ejb/FooBean")
private Foo mFoo;
}
Known bug? Or am I missing something here?
S.
