You are designing an enterprise web application consisting of several web applications which should share the same business object layer. You have several development teams, each experienced in only one of the following: Struts, Maverick, Spring, WebWork, and standard servlets and JSPs. Each team wants to implement their web application using the framework they know.

How do you design and implement a business object layer and its persistence for the above structure?

1)Entity Enterprise Java Beans (EJB) with Container Managed Persistence (CMP) must be used in order to provide shared business logic layer
2)Straight JDBC calls must be used to access the database, and be abstracted via interfaces
3)Any sound persistence methodology can be used, because a choice of implementation of business logic layer and its persistence is independent from a choice of web framework
4)Java Data Objects (JDO) must be used.
5)Create a set of factory objects which internally use either CMP, EJB or JDO

"RV RK",

This sounds an awful lot like homework to me. Can you let us know the source of these questions?
