Look Up a Bean Interface in EJB 3.0

Look Up a Bean Interface in EJB 3.0

In principle, in EJB 3.0, you can access a bean from another bean by looking it up in the interface (local or remote). Here are two solutions for doing that:

  1. Through the JNDI, you still have the portability:
    //get the default JNDI initial contextContext ctx=new InitialContext();//get the bussiness interfaceObject obj=ctx.lookup(BusinessInterface.class.getName());//convert objBusinessInterface bi=(BusinessInterface)obj;
  2. Through the @EJB annotiation:
    @EJB BusinessInterface bi;   //cooool !
