simpleClientClass(launced multiple threadClass) -------->
threadClass(each threadClass invokes an entityBean) ------> bmpEntityBean

-this setup, causes no delay and that the EJBContainer would
allow the next threadClass to proceed once the preceeding threadClass
has finished its transaction with the bmpEntityBean



simpleClientClass(launced multiple threadClass) ----> threadClass(each
threadClass invokes a sessionBean ----> statelessSessionBean(each sessionBean
invokes an entitBean) ----> bmpEntityBean

-this setup, however, causes the EJBContainer to perform strict
synchronization procedures..
i mean, the EJBContainer would allow another SessionBean to proceed
only after
another thread class has finished/termintated.
