First of all,
you should know these terms,
1> home object-- an instance of home interface implementation class which is generated by container. Every EJB class has only one home object.
2> home stub -- since home object is remote object, it must have stub.
3> ejb object -- an instance of your remote interface implementation class which is generated by container also. ejb object is created by home object.
4> ejb object stub -- the stub of an ejb object.
The situation you concerned doesnot exist. First of all, you call create(...) method on home stub which returns an ejb object stub. The ejb object is associated with an session bean instance. Your method call on ejb object stub will be forwarded to ejb object and then forwarded to the associated session bean instance.
