Programming Rules for Stateful Session Beans:

• The Stateful Session Beans maintain conversational state, so the instance variables must be Java primitives or Serializable objects.
• Since the SFSBs cannot be pooled like the SLSBs, there can be the risk of accumulating too many of them. So the client can explicitly request the removal of a bean by calling a method annotated with the @Remove annotation.
