Servlet not pass the value

[fabio alonso]

Hello,

I am with the following excerpt from my code, which is a problem. He should "create" this servlet and pass the value to my class, however, so the class returns null error

It seems that he is not creating the record. the code is this:

..
..
public class AdOrigem extends HttpServlet {
       protected void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {

       String codigoId = request.getParameter("naturezaId");
       Registro registro = new Registro();
       registro.setNatureza(codigoId);
       
        }
    }
..

Class accusing this error ..

..
..
   public Registro criaRegistro(Registro registro) {

        log.debug("novoRegistro()");
        EntityManager em = this.jpaResourceBean.getEMF().createEntityManager();

        try {
            log.debug("Persistindo registro");

            pedido.setData(new Date());
            pedido.setValor(new BigDecimal(0));

            em.getTransaction().begin();
            em.persist(registro);
            em.getTransaction().commit();

            return registro;
        } finally {
            em.close();
            log.debug("Saiu de novoRegistro()");
        }

    }
..

It turns out that the servlet is not creating the method. Anyone know what can be?

thanks

It turns out that the servlet is not creating the method

I'm not sure what you meant by this. Is it that you don't get the parameter value "naturezaId"?

...He should "create" this servlet and pass the value to my class...

It's actually when you send the request (GET in this case) to this servlet method "doGet" will be invoked and whatever inside that is executed...

Can you please TellTheDetails of the error you were referring to?
Was that perhaps criaRegistro(Registro) method generating some compile time errors or runtime exception?
