Submitting input type="image" to another servlet failed to return any parameters

servlet1:

I'm trying to pass parameters to another servlet2:

..

out.print("<input type='text' name='someText' src='someSrc' onclick='submit()'/>");

..

clicked it - servlet2 is loading.

servlet2:

protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();                
        Enumeration params = request.getParameterNames();
        while (params.hasMoreElements())
        {
            out.print("parameter: " + (String)params.nextElement() + "</br>");
        }
}

my output --> someText so far so good!

but when my input type is image my output is empty:

out.print("<input type='image' name='someText' src='someSrc' onclick='submit()'/>");

any suggestions?

As per the HTML specification, the input type="image" is to be used as an image map. The web browser will send the x and y position of the mouse pointer to the server when the end user clicks on the image map. 

out.print("<input type=\'image\' name=\'imgButton\' src=\'flowsheet/images/submit_button.gif\'/>");

The submitted value will be available as imgButton.x and imgButton.y

But,If you just want to use styled button in your page to submit data. Use input type="submit" where you can specify CSS background image for button.
