i'll expect reply. thanks for reading.
P.S)when i delete this parameter in source, there were errors
of course, i modified everyting related parameter "john".
but there were errors still~

Answer 1

The bean developer writes the create method for a Stateful Session Bean, so it's up to the developer
to decide which (if any) parameters are needed at creation time. If a particular parameter is not used
in the body of the ejbCreate method, that's a developer oversight. It's no different than writing any other
plain Java method that ignores one of its parameters. It's not a fatal error but it's probably indicative of
a mistake in the bean logic. All the EJB container cares about is that the signature of the create method
in the Home/LocalHome interface matches a corresponding ejbCreate method in the bean class.
