سؤال

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.

هل كانت مفيدة؟

Problem solved!

The strukture of the lookup is {deploymentId}{interfaceType.annotationName}. Therefore in my case it must be

initialContext.lookup("NameOfBeanLocal");

or initialContext.lookup("NameOfBeanRemote"); depending on the type of the interface.

To get the problem with JBoss solved you can switch from default lookup

new InitialContext().lookup("ejb:/ProjectName//NameOfBean!de." + "mypath.sessionbean.stateless.NameOfBeanInterface");

to something more flexible like Dependcy-Lookup or Dependency-Injection and use the @EJB annotation. Both ways are supportet by JBoss and OpenEJB.
