[jboss-user] [Beginners Corner] - Using the persistence manager in an entity bean

Greetings! I have an entity bean called person which has a 1:n relationship to another entity bean called job, which contains all jobs that this person has ever had. now, i'd like to have a function in person, which gives me only one of these jobs, namely the one he's currently working for. i did it already, and it nearly works, it looks like this: Job s; @Transient public Stelle getCurrentJob() { if(s==null){ EntityManager em = (EntityManager) Component.getInstance("entityManager"); Long sid = (Long) em.createQuery("fanceql").setParameter("id", this.id).getSingleResult(); s = em.find(Job.class,sid); } return s; } The problem is, that changes to Job are not saved to the database. why aren't they? is this bad design? how would you do it? niko View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4135642#...
