Hi to everyone on the list. I'm looking at the design options for a new app I'm working on. I have something like this so far:..
Struts framework --> invoke Action commands (execute) --> invoke Business Delegate methods --> lookup coarse-grained Session Bean --> invoke method on bean --> lookup factory for ORM system (Hibernate) --> manipulate data. My question is with regards to possibility of abstracting the persistence invocation out from the business tier to integration tier. I might wanna be switching to JDO for persistence in the forthcoming future and wish to make provision for change. If I decide to introduce a pattern such as DAO, my question is, will I loose the benefit of managed environment? I wanna use Session beans with CMT and to then invoke the persistence system indirectly via DAO.
