EJB - Can you use a bean within a bean

For example, can I do the following

@Stateless
@LocalBean
public class MyBean extends AbstractFacade<MyBeanEntity>
{   @PersistenceContext(UnitName='myPU")
    private EntityManager em;

    @EJB
    private MyBean2 bean2;
    @EJB
    private MyBean3 bean3;

    ....

}

For MyBean2 and MyBean3, they look like this

public class MyBean2 extends AbstractFacade<MyBean2Entity>开发者_开发百科
{   @PersistenceContext(UnitName='myPU")
        private EntityManager em;

        ....

}

public class MyBean3 extends AbstractFacade<MyBean3Entity>
{   @PersistenceContext(UnitName='myPU")
    private EntityManager em;

        ....

}

I need to do this because myBean need to call some business logic implemented in myBean2 and myBean3. But I am not sure if this will work or how the whole "@EJB bean injection" works in this situation. Any thoughts? Thanks alot!

Sure you should have no problem using @EJB within another EJB. Make sure you have @Local on top of your second bean class.
