Hi,
i recently saw a ValuListHandler question on this forum from a couple days ago, this helped me a little with my forwarding quetion, but i still have more doubts.

I`m developing a complete j2ee app (jsps, servlets, ejbs). Is the ValueListHandler pattern really usefull?

If so ...
- Is it better to implement with Statefull sessions or as a POJO?
- Does it matter if i use the ValueListHandler to access the db via DAOs or CMPs (cause i`m using CMPs basically)?

Thanks,
ltcmelo

In case, If you havent seen this ..

http://java.sun.com/blueprints/corej2eepatterns/Patterns/ValueListHandler.html

The 'Stateful Session Bean Strategy' explained in that link. I am concerned about the amount of Remotes calls we make, which would'nt be a good idea considering its expensive.

In my opinion use a normal Java ValueListHandler class, which uses stateLESS session bean or DAO imp class for the Data List creation with the help of CMP/JDBC and then ValueListHandler can iterate the list as normal.

Take a look at: http://mlavwilson.sourceforge.net/vlh . The ValueListHandler pattern is implemented as a bean, configured by spring. It can be wrapped by a stateless bean with little effort.

Or better yet the ValueListHandler sould be local to the client and the adapters
could make the remote calls if needed.
