Segue o meu persistence.xml


<?xml version="1.0" encoding="UTF-8" ?>

Segue o meu datasource ( mysql-ds.xml )


<datasources>
  <local-tx-datasource>

Quando eu tento executar o método no meu backend que seria responsavel por criar o EntityManagerFactory eu tenho a pilha de erro acima, segue a classe de teste que fiz:

public class JPAJNDIHelper {

    public static void initEMF(String unitName ) {
        String bindingName = "JPAJNDIHelper_" + unitName;
        try {
            InitialContext ctx = new InitialContext();
            EntityManagerFactory emf = Persistence.createEntityManagerFactory(unitName);
            ctx.rebind(bindingName, emf);
        } catch( NamingException e ) {
            throw new RuntimeException(e);
        }
    }
}

public class OlaMundo {
    public String ola(String nome){
        
        Setor setor = new Setor();
        
        setor.setDescricao( "Jpa Teste" );
        setor.setPercentual(new BigDecimal(54.6));
        
        EntityManager em= null;
        UserTransaction utx = null;
        try {
            JPAJNDIHelper.initEMF("TesteJPA");
            em = JPAJNDIHelper.getEntityManager("TesteJPA");
            utx = JPAJNDIHelper.getUserTransaction();

            utx.begin();
            em.joinTransaction();
            em.persist(setor);
            utx.commit();
            }
     }
// Codigo omitido

No caso é o método Ola que é chamado.

Se algeum tiver alguma ideia… valeu

Opa, blz?

O programa está tentando criar uma PersistenceUnit com o nome “TesteSiag”, não vi onde está esta String no seu código…
pode ser uma versão que você subiu antes para o servidor e ainda ficou por lá… faz o undeploy e depois o deploy novamente da app.
você pode simplificar o código tb e testar.


        Setor setor = new Setor();  
         
        setor.setDescricao( "Jpa Teste" );  
        setor.setPercentual(new BigDecimal(54.6));  

        EntityManagerFactory emf = Persistence.createEntityManagerFactory("TesteJPA");
        EntityManager entityManager = emf.createEntityManager();

        entityManager.getTransaction().begin();
        entityManager.persist(setor);
        entityManager.getTransaction().commit();

        entityManager.close();
        emf.close();

espero que ajude.
abraço

Tenta mudar o nome do PersistenceUnit, pois é no persistence.xml ele referencia TesteJPA, e no log no erro ele diz que não encontrou o TesteSiag, portanto o JBoss, tenta buscar pelo JNDI e não acha nada dando assim PersistenceException em relação nome. Conserta e posta o resultado. Valew.

Foi erro de digitação do post galera … na verdade os nomes estão iguais … =/

Não consigo configurar o maldito JTA pra trabalhar no JBOSS . =/
