I was looking at session facade
pattern and it is said that it can be SFSB or SLSB depending on the methods of the facade ( whether methods need to maintain states).
If it's SLSB we would not need to keep reference.
If it's SFSB, we would need a reference to be kept on client( business delegate pattern talks of caching reference to service i.e. session facade)
I have one question though. Do we have instances of BD's for each session then?
If BD is simple
java class, how do we achieve this?Where are BD's hold?
Can some expert help?
