I have started learning GWT and I would like to know if it is possible to create a form in GWT for a process such as user registration and then, handle the logic of the registration(extra validation, adding the data to the database, etc) in a spring controller. I have so far been unable to find resources on the web to do this, so I am guessing that what I am after might not be possible. Can this only be done using classes which extend the RemoteServiceServlet as shown in this video tutorial?

I have tried to access the data from my spring controller using the request.getParameter() method calls, what I noticed was that when I used the Post method, I was unable to access the form parameters, but when I use Get, I can access them. This is some of the code I am using:

GWT:

        HorizontalPanel hrzPnlname = new HorizontalPanel();
        hrzPnlname.add(new Label("User Name: "));

        final TextBox txtUserName = new TextBox();
        txtUserName.setName("userName");        
        hrzPnlname.add(txtUserName);...

Spring:

    @RequestMapping(method = RequestMethod.POST)
    public ModelAndView helloWorldFromForm(HttpServletRequest request)
    {
        Map<String, Object> model = new HashMap<String, Object>();
        System.out.println("------>\n\n\n\n\n\n" + request.getParameter("userName") + "\n\n\n\n\n<-------");...

I am using GWT 2.4. Any information on this would be highly appreciated.

Thanks!
