Dependency injecton failed with Glassfish

[Andras Nemeth Ii]

Hi!

I'm trying Glassfish 3.1 with Eclipse 3.6. I have a very simple session bean:

@Stateless(name="SessionTest", mappedName="ejb/SessionTest")
public class SessionTest implements SessionTestRemote, SessionTestLocal {

  
    public String getHelloWorld() {
    	return "HelloWorld!";
    }
    
}

And a web module where I would like to use the bean this way:

public class HelloBean{
	
	//@EJB(mappedName="ejb/SessionTest")
	private SessionTest st;
	
	public HelloBean() {
		InitialContext ctx;
		try {
			ctx = new InitialContext();
			st = (SessionTest) ctx.lookup("ejb/SessionTest");
		} catch (NamingException e) {
			e.printStackTrace();
		}
	}
	
	public String getHello() {
		if (st == null) {
			return "Sadly null";
		}
		return st.getHelloWorld();
	}
}

When I use the DI the result will be nothing. (st remains null) When try to recieve the bean via jndi lookup i get a java.lang.NoClassDefFoundError: session/SessionTest message on the lookup line. What do I mess up? It seems so simple...

Thanks!
