[jboss-user] [EJB 3.0] - Re: @EJB annotation injection broken in 4.0.5.GA

[doktora]

I've been testing two aspects: stateless beans and MBeans.

Here is all the code:


SomeBean -- stateless bean, it will be injected into TestBean.
package test;
  | 
  | @javax.ejb.Stateless
  | @javax.ejb.Local(SomeIntr.class)
  | public class SomeBean implements SomeIntr
  | {
  |   public String test() {
  |     System.out.println("SomeBean::test()");
  |     return "SomeBean::test()";
  |   }
  | }


TestBean -- a steless bean which has SomeBean injected, I have tried to clarify EJB with beanName, etc. -- same effect. In 4.0.5.GA this prints "Hello: null".
package test;
  | 
  | @javax.ejb.Stateless
  | @javax.ejb.Local(TestIntr.class)
  | public class TestBean implements TestIntr
  | {
  |   @javax.annotation.EJB
  |   SomeIntr some;
  | 
  |   public void hello() {
  |     System.out.println("Helllo: " + some);
  |     if(some!=null) some.test();
  |   }
  | }

This an MBean which tries to access TestBean in a few different ways -- injection, lookup, etc.

Calling testme() on this mbean prints "TEST ME: null / null".
Then after lookup and the call ti.hello() also prints "Helllo: null".

  | package test;
  | 
  | import javax.management.ObjectName;
  | import javax.management.MBeanServer;
  | import javax.management.MBeanRegistration;
  | import javax.annotation.EJB;
  | import javax.naming.InitialContext;
  | import javax.naming.Context;
  | import org.jboss.annotation.ejb.Service;
  | 
  | 
  | public class TestService implements TestServiceMBean, MBeanRegistration
  | {
  | 
  |   @EJB //(beanName="data/TestBean/local")
  |   TestIntr test;
  | 
  |   TestIntr test2;
  | 
  |   @EJB //(beanName="data/TestBean/local")
  |   public void setTest(TestIntr ti) { test2 = ti; }
  | 
  |   public void testme()
  |   {
  |     System.out.println("TEST ME: " + this.test + " / " + this.test2);
  | 
  |     try {
  |       InitialContext ctx = new InitialContext();
  |       TestIntr ti = (TestIntr)ctx.lookup("data/TestBean/local");
  |       System.out.println("TestIntr via lookup: " + ti);
  |       ti.hello();
  | 
  | 
  |     } catch(Exception e) {
  |       System.out.println("Could not lookup TestIntr: " + e.getMessage());
  |       e.printStackTrace();
  |     }
  |   }
  | 
  |   public ObjectName preRegister(MBeanServer server, ObjectName name) throws Exception {
  |     System.out.println("TestService :::::::::::::   preRegister");
  |     return name;
  |   }
  | 
  |   public void postRegister(Boolean registrationDone) {
  |     System.out.println("TestService :::::::::::::   postRegister");
  |   }
  | 
  |   public void preDeregister() throws Exception {
  |     System.out.println("TestService :::::::::::::   preDeregister");
  |   }
  | 
  |   public void postDeregister() {
  |     System.out.println("TestService :::::::::::::   postDeregister");
  |   }
  | 
  |   public void start() throws Exception {
  |     System.out.println("TestService :::::::::::::   start: " + this.test);
  |     testme();
  |   }
  |   public void stop() throws Exception {
  |     System.out.println("TestService :::::::::::::   stop");
  |   }
  | }
  | 


For completeness, here are the corresponding interfaces:

package test;

public interface SomeIntr
  | {
  |   public String test();
  | }

TestBean interface:

  | package test;
  | 
  | public interface TestIntr
  | {
  |   public void hello();
  | }

TestService interface

package test;
  | 
  | import org.jboss.annotation.ejb.Management;
  | 
  | public interface TestServiceMBean
  | {
  |   public void testme();
  | 
  |   public void start() throws Exception;
  |   public void stop() throws Exception;
  | 
  | }

To test this, I executed TestService.testme() from the JMX console.


Here are some more JBoss details:

[Server] Release ID: JBoss [Zion] 4.0.5.GA (build: CVSTag=Branch_4_0 date=200610162339) 
  | [Server] Server Name: default
  | [Server] Root Deployment Filename: jboss-service.xml
  | [ServerInfo] Java version: 1.5.0_07,Apple Computer, Inc.
  | [ServerInfo] Java VM: Java HotSpot(TM) Server VM 1.5.0_07-87,"Apple Computer, Inc."
  | [ServerInfo] OS-System: Mac OS X 10.4.9,i386


And this is from jboss-service.xml:

  |   <mbean code="clairetest.TestService" name="clairetest:service=testservice">
  |   </mbean>

Let me know if further info would be of use and if anyone can confirm this.

As I mentioned, JB405 was installed in EJB3-clustered mode via the jems installer.
