Ugh. tell your colleagues if they want to remove empty interfaces then *they* can be responsible for tracking down all the GenericDAO usages when the spec changes and ItemDAO actually needs something beyond CRUD.

and here goes my question about caching mechanisms.
I am developing an application using Flex,spring with BlazeDS.
In order to depict statistical information using different kind of charting components and for rich experience I am caching some data at client end.
To enhance response time furthur, I am caching the neccessary information at server side at server startup(have scheduler to update frequently).
As of now I have Delegates at server which decide whether to pull data from DB or from cache.
I am searching for any patterns for implementing caching in this kind of scenario.So, that I can well-organize the code and reuse the code at server end. Which pattern suit this well? or is there any better idea to implement it?
Any inputs are appreciated.
Thank you

If I understood your question correctly then my answer is Yes. Spring starting from 3.x follows OSGi framework and thats the reason you get bundle for each module rather getting everything in single spring.jar.
