Stateful Session Bean Caching

[Dain Sundstrom]

Hi all,

I've been thinking about SFSB caching, and have a few ideas about  
cache implements I'd like to experiment with like using Java5  
concurrent collections, ehCache, ServletSession and maybe Terracotta.   
Before I start experimenting, I'm going to try to simplify the  
interface between the StatefulContainer and StatefulInstanceManager  
(the cache).  Right now, if you want to plugin in a new cache, you  
have to either write a lot of EJB specific logic or subclass from our  
the existing StatefulInstanceManager, which sucks.  My goal is to  
extract a simple interface with just a few Map like operations that  
one would need to implement to introduce a new cache.

Anyway, just a heads up.  I'll post again when I have a initial draft  
of the interface available.  I'll also try to keep the existing  
extensions of StatefulInstanceManager in Geronimo working.
