[jboss-user] [Beginners Corner] - Project EJB and JSF designquestion - where to implement whic

I am developing an application with JSF and EJB 3.0. Now I have got a question where I should implement methods that manipulate my objects. Example1: The EJB SessioBean only implements methods to get data from the database and to persist or merge objects: EJB SessionBean courseHandler public void createCourse(Course course){ | em.persist(course); | } The managedBean courseBean manipulates the object: managedBean JSF courseBean | public void joinCourse(){ | currentUser = userHandler.getCmtUserByUserName(getRemoteUserName()); | currentCourse.getParticipants().add(currentUser); | currentUser.getCourses().add(currentCourse); | courseHandler.updateCourse(currentCourse); | CustomMessage.createMessage("course_joined"); | } Or should example 2 be the better version: The EJB SessionBean courseHandler manipulates the object and persists/merges it: public void joinCourse(CmtUser user, Course course){ | course.getParticipants().add(user); | user.getCourses().add(course); | em.merge(course); | } managedBean JSF courseBean public void joinCourse(){ | currentUser = userHandler.getCmtUserByUserName(getRemoteUserName()); | courseHandler.joinCourse(currentUser,currentCourse) | CustomMessage.createMessage("course_joined"); | } Thank you for your answers!
