Local Session Bean Call Exception in App Server

[Mark Cloutier]

I have been having trouble calling a Local Session bean in Glassfish.

I set up an example to show the exception I am having:


----------

MainBeanLocal

    package com.test;
    import javax.ejb.Local;
    
    @Local
    public interface MainBeanLocal {
    	void testCall();
    }

----------

MainBean:

    package com.test;
    
    import javax.ejb.Stateless;
    
    /**
     * Session Bean implementation class MainBean
     */
    @Stateless(mappedName = "ejb/MainBean")
    public class MainBean implements MainBeanLocal {
    	@Override
    	public void testCall() {
    		System.out.println("Test Call Succeeded");
    		
    	}
    }

----------

RemoteBeanRemote:

    package com.test;
    import javax.ejb.Remote;
    
    @Remote
    public interface RemoteBeanRemote {
    	public void callMainBean();
    }

----------

RemoteBean:

    package com.test;
    
    import javax.ejb.Stateless;
    import javax.naming.InitialContext;
    import javax.naming.NamingException;
    
    /**
     * Session Bean implementation class RemoteBean
     */
    @Stateless(mappedName = "ejb/RemoteBean")
    public class RemoteBean implements RemoteBeanRemote {
    	@Override
    	public void callMainBean() {
    
    		try {
    			InitialContext ctx = new InitialContext();
    			MainBeanLocal mb = (MainBeanLocal) ctx.lookup("ejb/MainBean");
    			mb.testCall();
    		} catch (NamingException e) {
    			// TODO Auto-generated catch block
    			e.printStackTrace();
    		}
    	}
    }

----------


Test Code:

    package com.test;
    
    import javax.naming.InitialContext;
    import javax.naming.NamingException;
    
    public class BeanTester {
    	public static void main(String[] args){
    
    		try {
    			InitialContext ctx = new InitialContext();
    			RemoteBeanRemote remote = (RemoteBeanRemote) ctx.lookup("ejb/RemoteBean");
    			remote.callMainBean();
    		} catch (NamingException e) {
    			// TODO Auto-generated catch block
    			e.printStackTrace();
    		}
    	}
    }

Output Trace:

What am I doing wrong when calling **MainBeanLocal**? I would like to avoid dependency injection, as if the MainBeanLocal was being called from a POJO.


Note: I have no trouble calling the RemoteBean.. I want to be able to call the local bean from the remote bean.

Did you try to lookup the stateless session bean in the BeanTester class instead of the remote session bean??
