Referencing EJB Local home from a POJO class of a separate web application

Question

I am trying to port 2 EJB modules in my application from EJB2.1 to EJB3.0. I am using the Eclipse Kepler IDE and regenerated the session beans using an EJB3.0 configuration. I am not using an ejb-jar.xml because in EJB 3.0 that is supposed to be redundant. I have instead used annotations for marking my bean as Stateless and specifying the Local and Local Home Interfaces. I have still kept the Local Home interface since I wanted the basic structure of my project to be similar to what it was in EJB2.1. I have also done away with the xml bindings for the EJB while migrating.

We are using a WAS 7 application server for deployment and while the EJB is getting successfully deployed without errors, I am getting a naming Exception while looking up my Local Home interface from a separate POJO class of a different web application it is required in. I basically want to call the create() method of the Local Home interface after referencing the EJB Local Home. Adding code samples below:

Session Bean:

@Stateless
@Local(AccessLDAPSessionLocal.class)
@LocalHome(AccessLDAPSessionLocalHome.class)
public class AccessLDAPSessionBean implements AccessLDAPSessionLocal {
//Business Logic
}

Local Interface:

public interface AccessLDAPSessionLocal {
//business Interface
}

Local Home Interface:

public interface AccessLDAPSessionLocalHome extends EJBLocalHome {

public AccessLDAPSessionLocal create() throws CreateException;

}

Pojo class referencing the Local Home interface:

public static AccessLDAPSessionLocal getAccessLDAPSessionBean() throws NamingException, CreateException {
    if (accessLDAPSessionBean == null) {
    InitialContext context = new InitialContext();
    Object obj = context.lookup("java:global/AccessLDAP/AccessLDAPSessionBean!com.ibm.asset.hrportal.core.ejb.ldap.AccessLDAPSessionLocalHome");
        accessLDAPSessionBean = ((AccessLDAPSessionLocalHome) obj).create();
    }
    return accessLDAPSessionBean;
}

Also my Local and Local Home interfaces are inside my EJB client which I use as a jar file, while my Session Bean is inside the actual EJB which is used as an EAR.

Following is the error I am getting:

NamingException::javax.naming.NameNotFoundException: Name global not found in context "java:".

Am I missing some configuration resulting in the failure of JNDI lookup? Any help would be gratefully appreciated. Thanks in advance.

Answer 1

I think the way you are looking up the ejb is not correct. The JNDI name would be something like "java:comp/env/". ejb-ref-name would be part of your web.xml

Also, you will need to give providerURL and factoryName to the context object before doing the lookup.
