Hi, you can use the Value List Handler design pattern. See http://www.corej2eepatterns.com/Patterns2ndEd/ValueListHandler.htm for an overview.
See http://www.theserverside.com/patterns/thread.tss?thread_id=26139 for an implementation. I never used it but it is seems very good. If you will use it please give us some feedback!
