How do I query a SharePoint List using a url and filtering on date?

Question

I am reading a SharePoint list using jquery.  Everything is working fine
except for the filter.  Each list item has an expiration date.  I want to retrieve JUST the items that have not expired (Expires > Today) but I can't figure out the url syntax and I've been searching all day for an example and
can't find one.  Could someone please help?!?  See bold code below.
Thanks,
Glen
$(document).ready(function ()
<strong>var qryWCFUrl = "/sites/MMTP1/_vti_bin/listdata.svc/MMAlerts?$filter=(Expires gt '08/10/2011')&$orderby=Title";
</strong> $.getJSON(qryWCFUrl, function (results)
$.each(results.d.results, function (i, mmAlert)
itemID = mmAlert.Id;
mmTitle = mmAlert.Title;
mmClass = mmAlert.ClassValue;
//alert("Item="+itemID+" Title="+mmTitle+" Class="+mmClass);
AddMMStatus(mmAlert.Id,mmAlert.Title,mmAlert.ClassValue);

Fadi,
Thanks for your response.  I actually have another version of the code that uses the SP client objects that works.  The problem is site boundries.  Let me give a more complete project explanation.
I am creating a master page for a new intranet.  As part of this master page, I want to read from an SP list of alerts and post each alert (if not expired) in the SP status bar.  I've gotten this to work with SP client objects and jquery (except
for the date filter part).  Both of these solutions work fine on the top site level.  BUT when trying it out at the sub-site level, the SP client objects version of my code fails. The jQuery version works except the date filtering.
I looked at the example from your link and it looks like a bit of a hybrid to my approaches:  JQuery with CAML.  My question is; does this example permit me to access a list in the top-level site from the subsites?  Please excuse my ignorance,
but I am an EXTREME newbie in this having spent the past 8 years as a VB.Net developer and a little bit of ASP.Net.
Below are the two different versions of my code in different versions of my master page definition:
SP Client Object Version
<script type="text/javascript">
// <![CDATA[
ExecuteOrDelayUntilScriptLoaded(LoadAlerts, "sp.js");
var ctx;
var currAlerts;
function LoadAlerts() {
ctx = new SP.ClientContext.get_current();
list = ctx.get_web().get_lists('/sites/MMTP1/Lists/').getByTitle('MMAlerts');
var cmlQry = new SP.CamlQuery();
var camlExp = '<query><Query><Where><Gt><FieldRef Name="Expires" /><Value IncludeTimeValue="FALSE" Type="DateTime"><Today /></Value></Gt></Where></Query></query>';
cmlQry.set_viewXml(camlExp);
currAlerts = list.getItems(cmlQry);
ctx.load(currAlerts,'Include(ID,Title,Class)');
ctx.executeQueryAsync(GetAlertsSuccess,GetAlertsFailed);
function GetAlertsSuccess() {
var lstEnum = currAlerts.getEnumerator();
while(lstEnum.moveNext()) {
var mmAlert = lstEnum.get_current();
AddMMStatus(mmAlert.get_item('ID'),mmAlert.get_item('Title'),mmAlert.get_item('Class'));
function GetAlertsFailed(sender,args) {
alert('Alerts load failed: ' + args.tostring);
function AddMMStatus(msgID, strTitle, strClass) {
var statID;
var statClass;
var statTitle;
statClass = "<a href=\"#\" onclick=\"javascript:DisplayAlert("+msgID+");\">" + strClass + ": </a>";
statTitle = "<a href=\"#\" onclick=\"javascript:DisplayAlert("+msgID+");\">" + strTitle + "</a>";
statID = SP.UI.Status.addStatus(statClass, statTitle, true);
SP.UI.Status.setStatusPriColor(statID,"red");
function DisplayAlert(msgID) {
var options = {
title: "Miller & Martin Alert!",
url: "/sites/MMTP1/SitePages/ShowAlert02.aspx?ID="+msgID,
allowMaximize: false,
showClose: true
SP.UI.ModalDialog.showModalDialog(options);
