EJB Client - Local Interface

[Amandeep Singh Ghai]

I am making my way to OCE EJB Certification & have one question.

* I created a EJB Project & a stateless Session Bean with a local interface
* In the same package I created a Java Class with Main method. This class has code like:

public class testP2p {

	@EJB
	public static p2pBeanLocal mBean;
	
	public static void main(String[] args) {
		mBean.produceMsg();
	}

}

Problem:
The mBean instance is always null. Somehow, dependency injection is not working. I also checked JBoss deployment & it does contains JNDI Bindings for this bean.

22:27:02,774 INFO  [org.jboss.as.ejb3.deployment.processors.EjbJndiBindingsDeploymentUnitProcessor] (MSC service thread 1-2) JNDI bindings for session bean named p2pBean in deployment unit deployment "p2p.jar" are as follows:

	java:global/p2p/p2pBean!test.p2p.p2pBeanLocal
	java:app/p2p/p2pBean!test.p2p.p2pBeanLocal
	java:module/p2pBean!test.p2p.p2pBeanLocal
	java:global/p2p/p2pBean
	java:app/p2p/p2pBean
	java:module/p2pBean

Please advise further!

Thanks, Aman

What kind of class is testP2p? A CDI or an EJB, or a POJO?

[Amandeep Singh Ghai]

testP2p is a normal POJO & is deployed together with the EJB in the same JAR file

[Frits Walraven]

POJO's are not managed by the container (unless it is a CDI-bean) and that is why this won't work. Make testP2p Stateless and you can see that works.

I added code like this but it still does not work. EJB Reference is still null.

@Stateless
public class testP2p {
 
    @EJB
    public static p2pBeanLocal mBean;
     
    public static void main(String[] args) {
        mBean.produceMsg();
    }
 
}

Please advise

You can't use static methods.

The easiest way to test your EJB is from a Servlet, which means you have to create a Dynamic Web Project in Eclipse.

How can I do JNDI lookup from application-client that is deployed together with EJB JAR in the same EAR file? I have seen several examples to connect remote-client to EJBs, but none that tells how to connect application-client (local EJB Client) to EJB using JNDI.

Please advise!
