I have tried the solutions implemented on the internet and none worked. What may be occurring?

Answer 1

The solution found was: 1st - Create the class JPAUtil to create the EntityManager

@ApplicationScoped
public class JPAUtil {

      private EntityManagerFactory entityManagerFactory = Persistence
        .createEntityManagerFactory("postgreSQL");


      public JPAUtil() {

      }

      @Produces
      @RequestScoped
      public EntityManager getEntityManager() {
          return entityManagerFactory.createEntityManager();
      }

      public void close(@Disposes EntityManager em) {
          em.close();
      }

}

2º - Map the class JPAUtil.java in the beans.xml as follows in the attribute bean-discovery-mode:

<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
                        http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
version="1.1" bean-discovery-mode="all">

But the annotation @ApplicationScoped already makes this mapping.
