[jboss-user] [EJB 3.0] - Re: can any one help me - having a bad day with ejb3 server

[wiggy]

in fact its worse than that i cant DI to work in the embedded server at all - never mind between it and the 4.2 AS.

i created a very simple test local EJB all in the embedded server project like this .  


  | // test ejb business interface defintion 
  | import javax.ejb.Local;
  | 
  | 
  | @Local
  | public interface Test 
  | {
  | 	public void message (String msg);
  | }
  | 
  | 

with a bean implementation like this 


  | import javax.ejb.Stateless;
  | 
  | 
  | @Stateless 
  | public class TestBean implements Test
  | {
  | 
  | 	public void message (String msg)
  | 	{
  | 		System.out.println ("test bean\n");
  | 	}
  | 
  | }
  | 

I then try and get the DI bit to trigger from the main client section with the main entry point 
calling client : - all in the same project

  | ...
  | public class ClientApp 
  | {
  | 	@EJB (name="Test")
  | 	public Test test;
  | 
  | 	public ClientApp () {}
  | 
  | 	public static void main(String[] args) throws Exception 
  | 	{
  | ... up to 
  | 
  | 	    //try dependency injection!
  | 		
  | 		new ClientApp().init ();
  | 		
  | 	    
  | 
  | 		
  | 		//Shut down EJB container
  | 		EJB3StandaloneBootstrap.shutdown();
  | 
  | 	}
  | 	
  | 	public void init()
  | 	{
  | 		//trigger the DI for test
  | 		test.message("local DI test in embedded container");
  | 	}
  | 	
  | ...
  | 
  | 

this gets the same null pointer ref
