Question

So I have one html form in “File1.html”

<form action="MyServlet" method="post">
    MyData: <input type="text" name="data"><br>
    <input type="submit" value="submit">
</form>

Then in my servlet I do the following:

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        RequestDispatcher myDispatch = request.getRequestDispatcher("File2.html");
    myDispatch.forward(request, response);
    }

So after the user hits the “submit” button in File1, the servlet takes the user to File2. But how do I access the data that was inputed in the first file in the second file?

Answer 1

before using the Dispatcher set the attribute you want to pass

request.setAttribute("AttributeName","This is the Attribute value.");

in your case

request.setAttribute("data",request.getParameter("data"));

and on the dispached page , get it by

String something =  request.getAttribute("data");
