There is a NPE being thrown here: UsuarioAction.java:45

what code is at that line??

6. Re: I get NullPointerException on entityManager.persist(obj)

diogossh Feb 12, 2010 1:13 PM (in response to diogossh)

thanks for your attention

line 45 is that:

public void salvarUsuario(){
try {
entityManager.persist(usuario); //Here NullPointerException happens

} catch (Exception e) {
facesMessages.add(Severity.ERROR,Erro ao salvar informações!!! ); // here line 45
}
facesMessages.add(Severity.INFO,Operação realizada com sucesso!!!);
}

7. Re: I get NullPointerException on entityManager.persist(obj)

cash1981 Feb 12, 2010 4:20 PM (in response to diogossh)

Try putting breakpoint and investigate the usuario object. See if any values are null.
If you dont know how to use breakpoint, just generate a toString and usario object and print it before you are running persist.
Also, avoid using facesMessage. Use StatusMessages instead.

babazs Feb 12, 2010 6:57 PM (in response to diogossh)

Instead of this:

<persistence:managed-persistence-context name="entityManager"
                                     auto-create="true"
                          entity-manager-factory="#{ControleManutencaoEntityManagerFactory}"/>

   <persistence:entity-manager-factory name="ControleManutencaoEntityManagerFactory"
                      persistence-unit-name="ControleManutencao"/>

You should use this:

     <persistence:managed-persistence-context
          name="entityManager"
          auto-create="true"
          persistence-unit-jndi-name="java:/xxxEntityManagerFactory">
     </persistence:managed-persistence-context>

and modify the persistence.xml to the folloeing way:

<property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect" />
               <property name="hibernate.hbm2ddl.auto" value="create-drop" />
               <property name="jboss.entity.manager.factory.jndi.name" value="java:/xxxEntityManagerFactory" />
