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:
