Re: OSCache and MVC

No, no, no!

If you're using EJB's, adding a second level cache is a BAD idea. One 
of the benefits of using ejb's in the first place is so you don't have 
to worry about caching. The container does it for you. Stuffing ejb's 
into oscache is an horrific abuse of both oscache and ejb's.
