Ajax and JSTL Query possible?

Question

Hi all ! I want to know if this is possible and if you have an example you could show. So far Im trying like this:
function ajaxFunction(){
     alert("ajaxFunction");
     var ajaxRequest;  // The variable that makes Ajax possible!
     try{
          // Opera 8.0+, Firefox, Safari
          ajaxRequest = new XMLHttpRequest();
     } catch (e){
          // Internet Explorer Browsers
          try{
               ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
          } catch (e) {
               try{
                    ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
               } catch (e){
                    // Something went wrong
                    alert("Your browser broke!");
                    return false;
     // Create a function that will receive data sent from the server
     ajaxRequest.onreadystatechange = function(){
          if(ajaxRequest.readyState == 4){     
          appendOptionLast(ajaxRequest.responseText);
     //var age = document.getElementById('age').value;
     //var wpm = document.getElementById('wpm').value;
     //var sex = document.getElementById('sex').value;
     //var queryString = "?age=" + age + "&wpm=" + wpm + "&sex=" + sex;
     //alert("Antes open");
     ajaxRequest.open("GET", "/TWC/Comun/Ajax.jsp", true);
     //alert("Despues open");
     ajaxRequest.send(null);
}And here is my JSP thats doing the query.
<%@page contentType="text/html"%>
<%@ page import="beans.*,java.util.*" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix=”sql” %>
<%@page pageEncoding="ISO-8859-1"%>
<sql:setDataSource dataSource=”jdbc/TWC” />
<sql:query var=”qryItems” >
    SELECT User_ID
    FROM product
    ORDER BY nombre
</sql:query>
<c:forEach var=”row” items=”${qryItems.rows}”>
     User: <c:out value=”${row.User_ID}” /><br> 
</c:forEach>Thanks!

thanks guys but I finally got it to work with JSTL and ajax.
The only "weird" thing is that when I parse the data to my JSP I get a bunch of white spaces at the end of each value for each field. Here is my code:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql" %>
<sql:setDataSource dataSource="jdbc/TWCApp" />
<sql:query var="producto">
select ITEMDESC AS name,IV00101.ITEMNMBR AS Number,USCATVLS_2 AS category,USCATVLS_1 AS Brand,
USCATVLS_3 AS Type,CURRCOST AS Invoice_price,
QTYONHND AS Stock_number, IV00102.LOCNCODE AS Location
from TWC.dbo.IV00101 JOIN TWC.dbo.IV00102 ON IV00101.ITEMNMBR=IV00102.ITEMNMBR
WHERE IV00101.ITEMNMBR = '${param.product}' AND IV00102.LOCNCODE = '${param.location}'
</sql:query>
<c:forEach items="${producto.rows}" var="row">
${row.name},${row.number},${row.category},${row.brand},${row.type},${row.Invoice_price},${row.Stock_number},${row.Location}
</c:forEach>Here is my JS:
ajaxRequest.onreadystatechange = function(){
          if(ajaxRequest.readyState == 4){     
          appendOptionLast(ajaxRequest.responseText);
function appendOptionLast(valor)
  //alert(valor);
  //var elOptNew = document.createElement('option');
  var elSel = document.getElementById('category_producto');
  var mySplitResult = valor.split(",");
  document.form1.nombre_producto.value=mySplitResult[0];
  document.form1.numero_producto.value=mySplitResult[1];
  document.form1.category_producto.value=mySplitResult[2];
  document.form1.brand_producto.value=mySplitResult[3];
  document.form1.type_producto.value=mySplitResult[4];
  document.form1.invoice_producto.value=mySplitResult[5];
  document.form1.stocknumber_producto.value=mySplitResult[6];
  if(mySplitResult[6]>0){
  document.form1.stock_producto.value="Available"
  else{document.form1.stock_producto.value="Out of stock"
  document.form1.location_producto.value=mySplitResult[7];So how I can get rid of all those extra spaces at the end of each value?
thanks!
