A problem with LocalHome

[vesuvius]

Hi guys,

I have a problem with EJB3 deployment.

Because we use a framework that performs EJB2.1-style calls, I have to specify a LocalHome interface for my stateless EJB3 bean. I made a small EJB to test how to do this. Here's the EJB:

@Stateless(name="Calculator")
@Local(CalculatorLocal.class)
@LocalHome(CalculatorLocalHome.class)
@LocalBinding(jndiBinding="ejb/local/Calculator")

public class CalculatorBean implements CalculatorLocal {
 int val = 0;

 public int plus(int num) {
 return num + val;
 }

 @Init
 public void ejbCreate() throws CreateException {
 this.val = 5;
 }

 @Remove
 public void ejbRemove(Object arg) throws RemoveException, EJBException {
 this.val = 0;
 }
}

Here's CalculatorLocal:

@Local
public interface CalculatorLocal {
 public int plus(int num);
}

Here's CalculatorLocalHome:

public interface CalculatorLocalHome extends EJBLocalHome
{
 public abstract Object create() throws CreateException;
}

Then, in the WAR file, I put the following in web.xml:

...
 <ejb-local-ref>
 <ejb-ref-name>ejb/local/Calculator</ejb-ref-name>
 <ejb-ref-type>Session</ejb-ref-type>
 <local-home>test.CalculatorLocalHome</local-home>
 <local>test.CalculatorLocal</local>
 <ejb-link>TestEJB.jar#Calculator</ejb-link>
 </ejb-local-ref>

(TestEJB.jar is the jar file that contains the above class and interfaces)

And then I buld an EAR file and I try to deploy it to JBoss 4.0.4 CR2. And JBoss throws the following error during deployment:

org.jboss.deployment.DeploymentException: Error during deploy; - nested throwable: (javax.naming.NamingException: ejb-local-ref: 'ejb/local/Calculator', with web.xml ejb-link: 'TestEJB.jar#Calculator' failed to resolve to an ejb with a LocalHome)

I know I'm doing something wrong but I don't know what. Any ideas?

Here's an excerpt from JBoss's Global JNDI Namespace:

+- ejb (class: org.jnp.interfaces.NamingContext)
| +- local (class: org.jnp.interfaces.NamingContext)
| | +- CalculatorHome (proxy: $Proxy134 implements interface test.CalculatorLocalHome)
| | +- Calculator (proxy: $Proxy133 implements interface test.CalculatorLocal,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBLocalObject)

Hope it helps.

I've opened a JIRA task for this issue.

Configure the web deployment descriptors this way:

web.xml

<ejb-local-ref>
 <ejb-ref-name>ejb/local/Session30</ejb-ref-name>
 <ejb-ref-type>Session</ejb-ref-type>
 <local-home>org.jboss.ejb3.test.servlet.Session30LocalHome</local-home>
 <local>org.jboss.ejb3.test.servlet.Session30</local>
 </ejb-local-ref>

jboss-web.xml

<ejb-local-ref>
 <ejb-ref-name>ejb/local/Session30</ejb-ref-name>
 <local-jndi-name>Session30LocalHome</local-jndi-name>
 </ejb-local-ref>
