Problem with sendToURL(). How can I solve it?

Question

Hi All,
I am new to flash and as3.
I have an issue with sendToURL() and navigateToURL() methods.
Here, i am placing the data present in my database into an Xml file. Again, i am parsing this xml file for accessing/retreival of data into flash using AS3's XML and XMLList classes and its methods etc.,
Collecting data from database to Xml file works fine. But, when we use navigateToURL(), a new browser window opens and required data is obtained to flash successfully.
In order to omit the new browser window, here, we are using sendToURL(). But, here, the Xml file is unable to create(not created). Hence, no data is passed from database to flash.
I also tried using URLLoader(but the same issue arises) whose code looks like this:
function createXml():void{
    var url:String = "http://localhost:8888/xmlServlet";
    var request:URLRequest = new URLRequest(url);
/*    var urlLoader:URLLoader = new URLLoader();
urlLoader.dataFormat = URLLoaderDataFormat.TEXT;
urlLoader.addEventListener(Event.COMPLETE, completeHandler1);
    trace("XML Loaded URL is"+url);
    var variables:URLVariables = new URLVariables();
    variables.viewid =String(comboBox_mc.selectedItem.data);
    //request.method=URLRequestMethod.POST;
    trace("variables.viewidvariables.viewid:"+variables.viewid);
    request.data = variables;
    //sendToURL(request);
navigateToURL(request);
//urlLoader.load(request);
/*function completeHandler1(event:Event):void {
    var loader:URLLoader = URLLoader(event.target);
    var succData:String=loader.data;
trace("in complete handler"+succData);
Please help me in this context.
Waiting for ur reply....
Thanks in advance.

Hi Greg Dove,
  My requirement is that,there is button in my application when i click on it,it creates a xml file with data from the database, after that the data is loaded in the the .fla file.The code snipplet is as follows:
submitBtn_mc.addEventListener(MouseEvent.CLICK,onCheck);
function onCheck(evnt:MouseEvent):void {
var url:String = "http://localhost:8888/xmlServlet";
    var request:URLRequest = new URLRequest(url);
    var variables:URLVariables = new URLVariables();
   variables.viewid =String(comboBox_mc.selectedItem.data);
   request.data = variables;
    sendToURL(request);    //this creates an xml file
    //For loading xml file and placing in .fla
    var xmlLoader:URLLoader = new URLLoader();
    xmlLoader.load(new URLRequest("humanap.xml"));
    xmlLoader.addEventListener(Event.COMPLETE, LoadXML);
    trace("values from xml are");
    function LoadXML(event:Event):void {
        var xmlData:XML = new XML();
        var xmlList:XMLList;
        xmlData = XML(event.target.data);
        xmlList = xmlData.children();
Here sendToURL(request); is not working.It is going to the serverside script but not creating the xml file.When i use navigateToURL(request); its working fine.PLEASE HELP ME...................
Thanks in advance
