problem of referring OSGI service from EJB (JBOSS - 7.1.1)

[jigneshmpatel]

On JBoss7.1.1.FInal, I am trying to call OSGI service from EJB but I am getting following error:

I also noticed jboss throws error while remove the service bundle.

How did you tell TestOSGi.jar that it can see HelloService.jar? It seems that you don't have the module dependency setup.

[jigneshmpatel]

ok at last got success to call service from EJB. In the bundle activator I forget to register services.

In case if somebody wanted to try in the future, attaching the reference codebase.

One thing I noticed while I unregister a service, somehow it prints for three times.

17:49:28,756 INFO  [stdout] (MSC service thread 1-2) Inside HelloServiceTracker.removedService HelloService:1.0.0.BUILD-2012-06-19

17:49:28,756 INFO  [stdout] (MSC service thread 1-2) Inside HelloServiceTracker.removedService HelloService:1.0.0.BUILD-2012-06-19

17:49:28,757 INFO  [stdout] (MSC service thread 1-2) Inside HelloServiceTracker.removedService HelloService:1.0.0.BUILD-2012-06-19

I would appreciate if somebody provide details of how to convert this codebase to blueprint container service.
