[jsp] how to pass data in an hidden field from one jsp page to another?

I have some data in an hidden field on a jsp page

<input type=hidden id="thisField" name="inputName">

how to access or pass this field onsubmit to another page?

The code from Alex works great. Just note that when you use request.getParameter you must use a request dispatcher

//Pass results back to the client
RequestDispatcher dispatcher =   getServletContext().getRequestDispatcher("TestPages/ServiceServlet.jsp");
dispatcher.forward(request, response);
