NullPointerException Getting swdl port

Question

I'm getting a NullPointerException when trying to connect with a WSDL.

When I test the web service it works perfectly. Also, the WSDL route is correct.

Here is the servlet who is calling the WS.

@WebServlet(name = "ValidationServlet", urlPatterns = {"/ValidationServlet"})
public class requestValidationServlet extends HttpServlet {

@WebServiceRef(wsdlLocation = "http://localhost:8080/Pagos/PagosService?WSDL")
private PagosService_Service service;

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
    processRequest(request, response);

    User user = new User()
    user.setName((String) request.getAttribute("name"));
    user.setLastName((String) request.getAttribute("lastname"));

    String validate = validation(user.getName(), user.getLastName());

}
private int validation(java.lang.String name, java.lang.String lastname, java.lang.String identification, java.lang.String mail, java.lang.String nit, int price) {
    org.pagos.service.PagosService port = service.getPagosServicePort();
    return port.validation(name, lastname, identification, mail, nit, price);
}
}

I'm getting the error when the service tries to get the port: service.getPagosServicePort().

And the error is this:

Warning:   StandardWrapperValve[ValidationServlet]: Servlet.service() for servlet ValidationServlet threw exception
java.lang.NullPointerException

It's not, I know what is a null Exception, the point is I don't know why is null when the servlet is trying to get the port of the web service. — rasfuranku, Nov 30 '17 at 19:30
your service field is null. So ehatever DI container you use, it is not set up correctly. — P.J.Meisch, Nov 30 '17 at 19:42
I think so, the stranger thing is, I tested it in another project and it works perfectly. — rasfuranku, Nov 30 '17 at 20:17
