  2. Hi,
    Actually business delegates decouples presentation and service tiers, and provides a facade and proxy interface to the services. Simply we can say it is like a shared classes between the clients and the EJB components.If u want give your mail-id i'll email to you some code examples.

  3. Does that mean that the delegate handles lookup of the EJBs.
    Also, where does it reside? In the EJB-jar along with the
    EJB or inside the WAR file.
