if I call 5 different setters on a CMP 2.0 bean is that 5 round trips to the DB? If so is there a way to batch the calls or get it so that it executes a single update rather than 5? Or does the container (Jboss 4) manage this for me? My Director who's a Softie and not familiar with J2EE was asking, because in a method call we called 5 setters for updating a users profile and he asked if it was 5 trips to the DB. I couldn't give a concrete answer. Any help of this would be great.
