hi arne, i used the EntityManager to get an EntityTransaction. you have to use cdi to create and inject it. (i used some producer methods.) i created @PersistenceUnit which is a cdi qualifier and @Transactional which is a cdi interceptor binding.
basically it works and it isn't hard to use. however, we have to think about an approach to provide as much as possible in a generic way. regards, gerhard http://www.irian.at Your JSF powerhouse - JSF Consulting, Development and Courses in English and German Professional Support for Apache MyFaces 2010/2/13 Arne Limburg <[email protected]> > Hi Gerhard, > > > > Did you mean „i used UserTransaction”?
