AJAX response conflit Résolu

Question

Bonjour, 

J'ai un problème avec ma redirection ajax, utilisant response. La redirection fonctionne parfaitement mais, plus tard, quand je dois retourner un booléen avec response, celui-ci retourne la redirection vers launch.html et non pas true ou false.

Voilà le code. Les lignes concernées sont commentées :

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class Worker extends HttpServlet {

    private static final long serialVersionUID = 1L;
    private static String firstName = "";
    private static String lastName = "";
    private static boolean doAnimWheel = false;
    private static String portion;

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        this.doPost(request, response);
    }

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        // begin recovering form
        Worker.firstName = request.getParameter("firstName");
        Worker.lastName = request.getParameter("lastName");

        response.sendRedirect("launch.html"); // TODO trouver pourquoi cela bloque response
        // end recovering form

        String param = request.getParameter("srcId");
        if(param != null) {
            if(param.equals("launch")) {
                Worker.doAnimWheel = new Boolean(request.getParameter("doAnimWheel")).booleanValue();
                return;
            }
            else if(param.equals("wheel")) {
                response.setContentType("text/plain");
                PrintWriter out = response.getWriter();
                out.print(Worker.doAnimWheel); // Ici je veux retourner un booléen, mais c'est launch.html qui est retourné
                out.flush();
                out.close();
                return;
            }
            else if(param.equals("result")) {
                Worker.portion = request.getParameter("portion");
                Worker.doAnimWheel = new Boolean(request.getParameter("doAnimWheel")).booleanValue();
                return;
            }
        }
    }
}

C'est bon, j'ai résolu mon problème. J'ai fais ainsi :

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        
        // begin recovering form
        String form = request.getParameter("form");
        if(form != null){
            Worker.firstName = request.getParameter("firstName");
            Worker.lastName = request.getParameter("lastName");
            
            response.sendRedirect("launch.html");
            form = null;
        }
        // end recovering form
        
        String param = request.getParameter("srcId");
        if(param != null) {
            if(param.equals("launch")) {
                Worker.doAnimWheel = new Boolean(request.getParameter("doAnimWheel")).booleanValue();
                return;
            }
            else if(param.equals("wheel")) {
                response.setContentType("text/plain");
                PrintWriter out = response.getWriter();
                out.print(Worker.doAnimWheel);
                out.flush();
                out.close();
                return;
            }
            else if(param.equals("result")) {
                Worker.portion = request.getParameter("portion");
                Worker.doAnimWheel = new Boolean(request.getParameter("doAnimWheel")).booleanValue();
                return;
            }
        }
    }
