Thanks for the suggestion. One of the implementations I've liked is the DatabaseLayer used in the jPetStore app by Clinton Begin over at iBatis.com. It uses a Factory pattern so that your actions work with interfaces while your concrete implementations can access just about anything. I'll have to check out the castor stuff though. I've used their xml databinding packages. jaaron __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
