[jboss-user] [EJB 3.0] - EJB3 Session Facade TransactionRequiredException

I was wondering the best way the handle the following with EJB3. I have a EJB3 Session Bean which acts as a facade for business activities. In a method, I want to check for existing records and report the error prior to attempting to persist an business object. I am looking for the existance of a database record (say user table with a username field). If the record exists, I return an error that already exists. When I try to find the user record, if not there a EJB3TransactionRollbackException is raised with the cause a NoResultException. I trap the exception but when I try to continue and persist the new record, I get a TransactionRequiredException. User user = null; // pseudocode try { user = em.findById(username); // throw already exists exception } catch (RuntimeException) ex) { // test cause and try to continue... desired path } if (user == null) { User user = new User(username); em.persist(user); } It appears that once a exception is raised, you cannot continue. How can I perform the database check and still continue? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3959641#...
