You need to define an ejbCreate() method with no parameters for an MDB.
If you define other ejbCreate() methods with different parameters,
they will not be called by the container for MDB or SLSB and hence there is no use for such methods.
From the exam point of view, U cannot have multiple ejbCreate() methods for MDB or SLSB.
