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?

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?

//--------------------------------------------------------
// Pagina Solicitada. Por defecto es 1
//--------------------------------------------------------
String pageString = StringUtils.defaultIfEmpty(request.getParameter("page"), "1");
long page = Long.parseLong(pageString, 10);
//--------------------------------------------------------
// Cuantas filas se quieren mostrar en el grid
//--------------------------------------------------------
String limitString = StringUtils.defaultIfEmpty(request.getParameter("rows"), "10");
long limit = Long.parseLong(limitString, 10);
//--------------------------------------------------------
// Indice de la columna donde se hizo click para ordenar
//--------------------------------------------------------
String sidxString = StringUtils.defaultIfEmpty(request.getParameter("sidx"), "1");
//--------------------------------------------------------
// Si se desea ordenar Ascedente o Descendente
//--------------------------------------------------------
String sordString = StringUtils.defaultIfEmpty(request.getParameter("sord"), "ASC");
//--------------------------------------------------------
// calcula numero de paginas para el query
//--------------------------------------------------------
long total_pages = 0;
if (count > 0) {
total_pages = (long) Math.ceil(count / limit) + 1;
}
//--------------------------------------------------------
// Si por alguna extraña razon la pagina solicitada es
// mayor que el total de paginas disponibles
//--------------------------------------------------------
if (page > total_pages) {
page = total_pages;
}
//--------------------------------------------------------
// Calcula fila inicial
//--------------------------------------------------------
long start = limit * page - limit;
//--------------------------------------------------------
// Si por alguna extraña razon la fila de inicio es
// negativa. Puede darse el caso en que el usuario teclee
// 0 para la fila inicial
//--------------------------------------------------------
if (start < 0) {
start = 0;
}

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.
