Injecting a POJO into an EJB3 SLSB with Spring 2.0.8

[_asc_]

Hello,

I want to inject a POJO into an EJB3 Stateless Session Bean with Spring 2.0.8 (I have to stick with this version because of JDO 1.0 compatibility).

I have found some resources on the net but no complete example, so I'm missing the big picture. Basically I have a Service-Interface "Service". This interface is implemented by the "ServiceImpl"-Pojo and the EJB. The EJB is called by a Java client and delegates all service calls to the service implementation. I understand, that I should use the Configurable annotation to inject the "ServiceImpl" - POJO into my EJB, so my classes look like this:

Service:

public interface Service
{
   public String sayHello();
}

ServiceImpl:

public class ServiceImpl implements Service
{
   public String sayHello()
   {
       return "Hello World!";
   }
}

ServiceEJB:

Configurable
Stateless
Remote(Service.class)
public class ServiceEJB implements Service
{
    private Service service;

    public String sayHello()
    {
         service.sayHello();
    }
}

I guess that the Configurable annotation causes Spring to instantiate a bean-factory in the background, but what I do not understand is where it is looking for the configuration file?

So I'm a bit confused how these components are "glued" together and what effects the Configurable annotation really has.
I hope that someone can help me.

Thank's in advance!

Can I use EJB3 and Hibernate as Persistence mapping?
