Put at the begining of your JSP

<%@ page contentType="text/html; charset=iso-8859-1"
         language="java"
         import="bcv.utilidades.Constantes"
         errorPage="" %>

In "import" places the jakarta libs and any other lib you would need separated by commas.

        //--------------------------------------------------------

I need translate this PHP code in JSP code!

$page = $_GET['page']; // get the requested page
$limit = $_GET['rows']; // get how many rows we want to have into the grid
$sidx = $_GET['sidx']; // get index row - i.e. user click to sort
$sord = $_GET['sord']; // get the direction

Any idea?

On the server (server.jsp), to capture the values passed by the browser, I'm using:

String _page = request.getParameter ( "page");
String _limit = request.getParameter ( "rows");
String _sidx = request.getParameter ( "sidx");
String _sord = request.getParameter ( "deaf");

But all values are caught NULL. What can I do to take the real values?
