#38 JWebBrowser WebBrowserNavigationParameters Fail

[Anonymous]

I run into some problems with submitting parameters to a servlet. The parameters can be seen just before it performs the native call but then never reach the server.

[u]Here is my test case.[/u]

I create a basic servlet :

/* Servlet implementation class GreetingServlet /
public class GreetingServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public GreetingServlet() {
super();
}
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
doGetOrPost(request, response);
}
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
doGetOrPost(request, response);
}
protected void doGetOrPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = response.getWriter();
response.setContentType("text/plain");
String name = "";
String value = "";
Enumeration enumeration = request.getParameterNames();
for (; enumeration.hasMoreElements();) {
name = (String) enumeration.nextElement();
out.println(name);
value = request.getParameter(name);
String[] values = request.getParameterValues(name);
for (int i = 0; i < values.length; i++) {
out.println(" " + values[i]);
}
}
out.close();
}
}

[u]Here is my launcher[/u]
public class NakedImpl extends JFrame {
private JWebBrowser webBrowser;
JMenuBar mnuBar;

public NakedImpl() {
    webBrowser = new JWebBrowser();
    setTitle("Naked Implentation-Launching JWebBrowser");
    setLayout(new BorderLayout());
    setJMenuBar(getTheMenuBar());
    add(webBrowser, BorderLayout.CENTER);
}
private JMenuBar getTheMenuBar() {
    if (mnuBar == null) {
        mnuBar = new JMenuBar();
        JMenu mnu = new JMenu("File");
        JMenuItem exit = new JMenuItem("Exit");
        exit.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                System.exit(1);
            }
        });
        JMenuItem navigateToMyFirstServlet = new JMenuItem("navigateToMyFirstServlet");
        navigateToMyFirstServlet.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                try {
                    navigateToMyFirstServlet();
                } catch (MalformedURLException e1) {
                    e1.printStackTrace();
                }
            }
        });
        mnu.add(exit);
        mnu.add(navigateToMyFirstServlet);
        mnuBar.add(mnu);
    }
    return mnuBar;
}


public void navigateToMyFirstServlet() throws MalformedURLException {
    WebBrowserNavigationParameters wparm = new WebBrowserNavigationParameters();
    Map<String, String> postDataMap = new HashMap<String, String>();   
    postDataMap.put("username", "marius");   
    postDataMap.put("password", "password");   
    wparm.setPostData(postDataMap);
    Map<String, String> headersMap = new HashMap<String, String>();   
    headersMap.put("User-agent", "Native Swing Browser");   
    headersMap.put("method", "post");
    wparm.setHeaders(headersMap);
    webBrowser.navigate(
            "http://localhost:8080/MyFirstServlet/GreetingServlet", wparm);
}

public static void main(String[] args) throws MalformedURLException {
     NativeInterface.open();
     SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            JFrame frame = new NakedImpl();
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.setSize(800, 600);
            frame.setLocationByPlatform(true);
            frame.setVisible(true);
        }
    });
     NativeInterface.runEventPump();
}
