Hi gerhard,
thanks for your Reply. I think that the TransactionalInterceptor and TransactionalInterceptorStrategy gets calles from codi (org.apache.myfaces.extensions.cdi.jpa.impl.transaction) and no Transaction is available. This Interceptor to start a Transaction is not called when we use generics in the IpersonDaoSuperInterface. Regards steffen Von: Gerhard Petracek [mailto:[email protected]] Gesendet: Mittwoch, 20. März 2013 10:20 An: MyFaces Development Betreff: Re: Apache Myfaces12 Codi Tomcat 7 - Transaction Problems short addition - that means: codi isn't responsible to trigger the interceptor itself. that's the part openwebbeans has to do. regards, gerhard http://www.irian.at Your JSF/JavaEE powerhouse - JavaEE Consulting, Development and Courses in English and German Professional Support for Apache MyFaces 2013/3/20 Gerhard Petracek <[email protected]> hi steffen, first of all: welcome @ myfaces if EntityTransaction#begin and (#commit or #rollback) get called, the part done by codi is fine and it's a different issue. regards, gerhard http://www.irian.at Your JSF/JavaEE powerhouse - JavaEE Consulting, Development and Courses in English and German Professional Support for Apache MyFaces 2013/3/20 <[email protected]> Hello, Problem with codi(1.0.5) Transactions and Java (1.6/1.7) generics. Infrastructure: Myfaces12 Jpa2 (eclipslink 2.4) Codi 1.0.5 Tomcat 7 OpenWebBeans 1 See Classes below Problem is: When we inject the Interface IpersonDao in the Service Class (PersonServerImpl) and do the following: dao.delete(person) à No Transaction is openend and nothing happens!!!!! doa.persist(person)à Transaction is opened and entity is saved. Difference is that in the IpersonDaoSuperInterface the delete function contains generic arguments and the persist fuction has a concrete Object (person). But we need the generic type for all function in the IpersonDaoSuperInterface. When we inject the Concrete Implementation of the dao ( @Inject private PersonDao dao) in PersonServerImpl the delete function also works. Question. Why cant we inject the Dao Interface when we use java generics in the interface hierarchy??? Service Class: public class PersonServerImpl implements PersonService { @Inject private IPersonDao dao; public void removePerson(Person person) { dao.delete(person); } public Person savePerson(Person person) { return dao.persist(person); } } Dao Class: public class PersonDao implements IPersonDao { @Transactional public void delete(Person entity) { em.remove(em.merge(entity)); } @Transactional public Person persist(Person entity) { em.persist(entity); return entity; } ... } IpersonDao Interface: public interface IPersonDao extends IpersonDaoSuperInterface<Person> { public abstract List<Person> loadAll(); public abstract Person loadById(Serializable id); public abstract List<Person> findByLastName(String lastname); } IpersonDaoSuperInterface: public interface IpersonDaoSuperInterface<T extends DbObject> { public abstract void delete(T entity); public abstract Person persist(Person entity); public abstract T update(T entity); } Thanks fore help steffen
