Getting an EJB session bean which uses @SecurityDomain annotation, in a unit test case through JNDI

[Nitin Bhardwaj]

Hi Friends,
I am a novice in setting up unit testing framework. I am trying it for a Struts+EJB3 application. I intend to write a test case for each method that I write in a EJB3 session bean.
I wrote the following simple test class:

package com.stryker.gim.ejb.session.item;

import static org.junit.Assert.*;

import java.util.Properties;
import javax.naming.InitialContext;

import org.junit.Before;
import org.junit.Test;

import com.stryker.gim.ejb.entity.ItemBean;
import com.stryker.gim.ejb.session.item.remote.ItemServiceRemote;


public class JndiTestCase {
	
	private ItemServiceRemote itemServiceBean = null;
		
	@Before
	public void bootContainer() throws Exception {		
				
		Properties props = new Properties();
		props.put("java.naming.factory.initial",
				"org.jnp.interfaces.NamingContextFactory");
		props.put("java.naming.provider.url", "jnp://localhost:1499");  // I've configured JNDI port to be 1499.
		props.put("java.naming.factory.url.pkgs", "org.jnp.interfaces");
		InitialContext ctx = new InitialContext(props);
		System.out.println("Initial context :: " + ctx);
		itemServiceBean = (ItemServiceRemote) ctx.lookup("gim/ItemServiceBean/remote");
		System.out.println("Hi Nitin inside bootContainer...itemServiceBean="+itemServiceBean);
		assertNotNull(itemServiceBean);
	}	
	
	@Test
	public void testFindItemByItemId()
	{
		System.out.println("Running The TestCase :: testFindItemByItemId");
		ItemBean itemBean = itemServiceBean.findItemByItemId(427850);
		assertEquals("BPLK000324", itemBean.getCatalogNumber());
	}
	
}

In above the ItemServiceRemote interface is the Remote interface which is being implemented by the stateless EJB: ItemServiceBean. The gim.ear is the name of the EAR file. Hence, I use "gim/ItemServiceBean/remote" for lookup. The ItemServiceBean has been annotated with @SecurityDomain annotation defined in org.jboss.annotation.security.SecurityDomain.
When I run the above test case then I get the following exception:

(The application uses JAAS/LDAP for Authentication and Authorization.)
Request you to help me in knowing the solution for this problem.
Thank You !
