You can make an ejbCreate method that takes a data transfer object as a parameter.
But take a look at "EJB Design Patterns" ( http://www.theserverside.com/resources/index.jsp ).
It advices to use fine grained getXXX setXXX methods through local interface, not DTO's as set/get parameter or ejbCreate
with a lots of arguments.
