I didn't success to call a servlet inside another servlet

Question

I have servlet A where there is this code :

protected void doPost(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {

    RequestDispatcher rd = request.getRequestDispatcher("gestion-avis");
    rd.forward(request, response);

}

And then another servlet B which refers to "gestion-avis" :

@WebServlet("/gestion-avis")
public class GestionAvisServlet extends HttpServlet

The code of the A servlet normally redirect to the doGet method of the servlet B.

But this redirect me to an empty html page called "gestion-avis".

Thank you for your help !

This could be the reason for your issue.

Since you are forwarding request to another servlet mapped at url gestion-avis, the request goes to your GestionAvisServlet and its doGet method.

Now if your GestionAvisServlet.doGet method is not writing any data to HttpServletResponse, you will get a blank screen.

So to see some data either you need to write data to HttpServletResponse like this:

public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws IOException {
        response.getWriter().println("Hello");
 }

Otherwise you can forward to another page.

But at runtime this is not entering in the method GestionAvisServlet.doGet. – jozinho22 May 17 '20 at 17:03
I don't want to write something, i want to forward the request to another jsp page – jozinho22 May 18 '20 at 17:56
The program just don't enter in GestionAvisServlet.doGet – jozinho22 May 18 '20 at 17:57
Actually when I do request.getRequestDispatcher("gestion-avis"), this enter to the GestionAvisServlet.doPost() method, and not the doGet()... – jozinho22 May 19 '20 at 10:36
