How to post data and redirect to another page using GWT? - gwt

Question

When I press a button I post some data to server and there redirect to another page.
I used RequestBuilder but it is waiting the response, and of course get it. And nothing happens, same page stays. I see RequestBuidler shouldn't be used here... What should I use to post data and be able to redirect?
In Spring
#RequestMapping(method=RequestMethod.POST, value="/ddd")
public ModelAndView processOrder(#RequestBody String orderInString, HttpSession session) throws Exception{
...
return new ModelAndView(new RedirectView("abc"));
}
In GWT
public void postData(final String data, final String url) {
RequestBuilder builder = new RequestBuilder(RequestBuilder.POST, url);
try {
builder.sendRequest(data, new RequestCallback() {
public void onError(Request request, Throwable exception) {
...
}
public void onResponseReceived(Request request,
Response response) {
if (200 == response.getStatusCode()) {
..
} else {
..
}
}
});
} catch (RequestException e) {
...
}
return;
}

FormPanel form = new FormPanel("_self");
form.setMethod(FormPanel.METHOD_GET);
Hidden params0 = new Hidden("param1", "value1");
Hidden params1 = new Hidden("param1", "value2");
Hidden params2 = new Hidden("param2", "value3");
FlowPanel panel = new FlowPanel();
panel.add(params0);
panel.add(params1);
panel.add(params2);
form.add(panel);
form.setAction(GWT.getModuleBaseURL() + "../MyServlet");
RootPanel.get().add(form);
form.submit();
Thats it. The code adds FormPanel and sends form.

Add more specifications, code, this is blur.
Since you are using Spring-mvc, you should be having something like this
private static final String newPage = "index2"; //this is resolved with view resolver
#RequestMapping(params = "action=button")
protected String getALPLicense(final RenderRequest request,
final RenderResponse response, final Model model) throws Exception {
try{
}catch{
}
return newPage; //this is your new redirected page
}
