Problem setting up OpenEJB in Eclipse

[yumariso <yu...@fastmail.fm>]

Hi,

I am trying to set up an EJB 3 test project in Eclipse and I am hitting on a
problem I can't find any explanation elsewhere. I am an EJB newbie so I may
be missing something trivial...

I downloaded the latest OpenEJB 3.1.1 and added all of its libraries to a
User Library set. I made a new Java project that contains the following
three classes:

file: test.Simple

package test;

public interface Simple {
	public int multiply(int a, int b);
}

file: test.SimpleBean

package test;

import javax.ejb.Stateless;

@Stateless
public class SimpleBean implements Simple {

	public int multiply(int a, int b) {
		return a*b;
	}
}

file: SimpleTest

import static org.junit.Assert.*;

import java.util.Properties;

import javax.naming.Context;
import javax.naming.InitialContext;

import org.junit.Test;

import test.Simple;


public class SimpleTest {

	@Test
	public void testSimple() {
		Properties p = new Properties();
		p.put(Context.INITIAL_CONTEXT_FACTORY,
				"org.apache.openejb.client.LocalInitialContextFactory");
		InitialContext context;
		try {
			context = new InitialContext(p);
			Simple simple = (Simple)context.lookup("SimpleBeanLocal");
			assertEquals(simple.multiply(2,2), 4);
		}
		catch ( Exception e ) {
			e.printStackTrace();
		}
	}
}

I have ejb-jar.xml in META-INF folder under the src folder with just
'<ejb-jar />' in it. When I run the test I get the following output:

The problem was that I set up the OpenEJB User Library as System Library. If
I uncheck it it works as expected.
