    No persistence provider for EntityManager named scrum

    Rafael Jesus Newbie

      Hey all,

       

      After 2 weeks configuring my Java app with maven + jboss as 7, i can´t run my simple junit tests, here goes my code and how im configuring my persistence.xml:

       

      PS: My Web app is ok, just tests is not working

       

      public class TestUsuarioRepository {
        
                private static EntityManager em; 
                private static UsuarioDao usuarioDao;
      
      
                @BeforeClass 
                public static void before() throws Exception {
                          em = new JPAUtil().getEntityManager();
                          usuarioDao = new UsuarioDaoImpl();
                }
      
                @AfterClass
                public static void after() throws Exception { 
                          em.close();
                }
      
                @Test     
               private void salvaNovoUsuario() throws Exception 
                          final Usuario u = new Usuario(); 
                          u.setNome("Rafael");
                          u.setLogin("adm");
                          u.setSenha("123");
                          u.setRole(UsuarioRole.TEAM);
                          usuarioDao.salva(u);
                          assertNotNull(u.getId());                     
                }
        }
      
      

       

       

      public class JPAUtil {
      
                private static EntityManagerFactory factory = Persistence.createEntityManagerFactory(Const.SCHEMA);
      
                @Produces 
                @RequestScoped
                public EntityManager getEntityManager() {
                          return factory.createEntityManager();
                }
      
                public void close(@Disposes EntityManager em) {
                          em.close();
                }
      }
      
      

       

      Here if i don´t map my entities, when i run my web app, it does not find my mapped classes, so Why?

                Thanks for responding Scott, and sorry for the delay .. as requested follows the trace of the exception. I even thought the error was because of the libraries are as provided in the pom as you can see here https://github.com/rafaeljesus/agile2go/blob/master/pom.xml

                 

                but that it is not..so I got very cofusing, here the problem:

                 

                tks..

                  It looks like you have written a Hibernate application that can mostly run outside of the AS7 server, except your depending on the AS7 server to define the java:jboss/postgresDS datasource and probably other things. 

                   

                  I think that you should look at using Arquillian which addresses what your trying to accomplish.

                   

                  Take a look at http://www.jboss.org/arquillian.html and the doc here.

                    Hi Scott,

                     

                    Tks for the answer, i did not know that i could test aquillian with junit tests..

                     

                    I´ll try later,

                     

                    Tks a lot,

                     

                    Cheers

                      By the way, Arquillian just got a brand new site http://arquillian.org/ and (probably) more up-to-date guides here http://arquillian.org/guides/

                          Just to answer All I´d did to run tests, create tables, etc... was to comment in my persistence the the tag <jta-data-source>java:jboss/postgresDS</jta-data-source>

                           

                          Tks for all
