if i use a set method on a entity bean when inside a session bean, the method has the desired effect (i e the data is propelled down to the database), but if try the same set-method when inside the web layer (as in a JSP page) it does not have any effect.
should it have an effect? it would be nice.
no, it should not. use em.merge() to save changes of a detached entity back to db.
