Thank you for sharing your thoughts. Yes, @Service along with @PostConstruct should work. But I really can't find the jar which has the @Service annotation. Like i said i am using Jboss 5.1. Does the jar comes with the Jboss 5.1?

Thanks

Thank You Jaikiran.

I was able to get the jboss-ejb3-ext-api.jar and also I created a class which has @Service and @PostConstruct. As you suggested i also ran the plugin (and I could see it ran correctly - which was really Awesome!). As expected the PostConstruct method is called during the Jboss startup (whowhoo..i was so excited).

   But when i updated my @PostConstruct method to call a EJB method to get records, it is failing with the below error:

17:46:27,511 ERROR [ServiceContainer] Encountered an error in start of PropertyRegistryServiceImpl

java.lang.RuntimeException: javax.ejb.EJBTransactionRequiredException: public java.util.Collection com.tixx.persistence.properties.manager.impl.ApplicationPropertyManagerImpl.findAllApplicationProperties()

It seems like the transaction (EntityManager) is null. I am using EJB3 with Hibernate. Below is my code snippet:

@Service
@Remote( { com.tickets.service.properties.PropertyRegistryServiceRemote.class })
@TransactionAttribute(TransactionAttributeType.REQUIRED)
public class PropertyRegistryServiceImpl implements PropertyRegistryServiceRemote{

    @EJB
    EntityManager entityManager;

  
    @PostConstruct
    public void applicationStartup() {
     System.out.println("Jboss Properties Initializing!!!!!");
     try{
      Collection<ApplicationProperty> props = this.entityManager.findAllApplicationProperties(AppContextHolder.getUserContext());
     }catch(Throwable e){
      System.out.println("Jboss Properties Initializing ERROR: "+ e);
     }
    }
}

Any idea what am i missing here?

Thanks Ales for the reply.

I was stupid and it was a code mix up and entityManager was the issue and i got ALL working yesterday night!!!!

A wrap up of what I did to make it work:

• Created a class with @Service and @Remote annotation.
• The class has a method with @PostConstruct annotation and this method will call a EJB (via Hibernate) and get all my records (property name/values) from database.
• Make sure to have  jboss-ejb3-ext-api.jar and run the necessary plugin as mentioned by Jaikiran.

Thank You all. I AM IN LOVE WITH JBOSS 5.1

Thank you for the support. I do have a question in regards to the plugin which i ran for the Jboss 5.1.

I was wondering what exactly does it do when i run the plugin? I mean are we adding new jar files to different directory under Jboss home? The reason i asked is i will have to do the same to my QA / Production environment. I am little hesistant to run this directory in production.
