what is session facade ?..

It is Design pattern
Problem:too many method invocations b/w client and server
will lead to network overhead,tight coupling due to
dependencies between the client and server and chance of
misuce of server business methods due to fine grained
access etc.
Solution: Use of session besn as facade to encapsulate the
complexties b/w the client and server interactions. The
session facade manages the business objects and provides a
uniform coarse grained service access layer to client.
