903603Dec 6 2011 — edited Dec 6 2011hi,
i am trying to get a hiddenField value on servlet but i am getting a null value, how to solve this?
my jsp code look like this:
<form action="ImageResizeServlet" method="post">
<input type="hidden" id="pageWidth" name="pWidth"></input>
</form>
and my servlet code look like this:
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try {
String s=request.getParameter("pWidth");
....
what to do?
thank you.
