While it is true that create() and ejbCreate() methods for a stateless bean
cannot take any parameters, but when a client calls create() method on a
stateless bean, ejbCreate() is not called on the bean instance. When an EJB
server starts up, it creates a certain amount of stateless bean instances,
calls the ejbCreate() method for each of them and stores them in the pool.
Subsequently, when a client invokes create() method on the home, the server
simply picks up an instance randomly and associates it to the EJBObject. This
is significantly different from Entity and Stateful beans for which, the
create() method is despatched to the corresponding ejbCreate() method.
I hope my understanding is correct. If there is anything wrong, please correct
me. Thanks.
