Value-list handler, value-list iterator and session-facade strategy
Joined: Apr 24, 2004
Hello all, Further to an earlier post, I rewrote my post trying to me more accurate in my question. Here is my problem: I am trying to implement the value-list handler design pattern using the session facade strategy. In the pattern as it is described here (http://java.sun.com/blueprints/corej2eepatterns/Patterns/ValueListHandler.html) the client accesses the value-list handler AND the iterator directly. As I chose the session-facade strategy having my value-list handler as a stateful session ejb, I don't know how the client is going to access the iterator. I see only one option: Having the client access the iterator through the ejb value-list handler. This requires adding new methods to the ejb. Is this the correct way of doing it? Is there another way of doing this? Thanks in advance, Julien Martin.

I don't think I understand the problem. Won't the session bean be returning a Collection of Transfer Objects to the client? In this case, the client can then locally iterate over the Collection.
