Its the first time I used the OpenEJB container system. When I use the lockup-Method of the InitialContext, I get a NameNotFoundException. I’ve read lots of examples and tutorials and in every example the lookup method looks like:
initialContext.lookup("NameOfBean");
Now I’ve found another solution which uses the lookup like the following code snippet which works for me too.
initialContext.lookup("java:global/classpath.ear/ProjectName/NameofBean");
The question is why the first version doesn’t work for me and what I’ve done wrong?

This is my TestClass:
public class NamerOfBeanOpenEJBTest {
private static InitialContext initialContext;
@BeforeClass
public static void setUp() throws Exception {
Properties properties = new Properties();
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.client.LocalInitialContextFactory");
properties.setProperty("openejb.deployments.classpath.include", ".*");
initialContext = new InitialContext(properties);
}
@Test
public void testBean() throws NamingException{
Object object = initialContext.lookup("java:global/classpath.ear/ProjectName/NameOfBean");
assertNotNull(object);
assertTrue(object instanceof NameOfBean);
}
@AfterClass
public static void afterClass() throws Exception {
if (initialContext != null) {
initialContext.close();
}}
}
Does someone have tipps or solutions for me?
Thanks a lot.
Edit:
In JBoss AS 7.1 the lookup can places like this example:
new InitialContext().lookup("ejb:/ProjectName//NameOfBean!de." + "mypath.sessionbean.stateless.NameOfBeanInterface");
Isnt that possible in OpenEJB? Do I have to change every lookup call in every bean to have a local test with OpenEJB? That wouldn’t be really effective and time-saving.
Problem solved!
The strukture of the lookup is {deploymentId}{interfaceType.annotationName}. Therefore in my case it must be
or
initialContext.lookup(“NameOfBeanRemote”);
depending on the type of the interface.
To get the problem with JBoss solved you can switch from default lookup
to something more flexible like Dependcy-Lookup or Dependency-Injection and use the @EJB annotation. Both ways are supportet by JBoss and OpenEJB.
