Calling Reporting Services Web Service with jQuery possible?

Hi,

is it possible to call the Reporting Services Web Service with jQuery? If yes, can someone post me a small example?

Background:

My plan is to create a html with a form which is also uploaded then into the reportserver. I open this html later by clicking a link in a report (with gotoURL open.window). The report opens the html inclusive the overtaken of some additional parameters (reportname, reportdescription). These parameters I will use in the html-form as defaultvalues for the corresponding input-text-fields. Now the user can make some changes (i.e. the decription). With a click on a button I will send the new description to the Reporting Services Web Service by using the SetProperties method, closing the html-window and reload the report. Important is that I want to upload the html also into the reportserver itself.

I have already found how to consume a web service via jQuery but with the Reporting Services Web Service I did not get it running in my tests.

I have referenced to the following jQuery.js: http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js

Here you can see my tests I made with the results:

$.ajax({
	type: 'POST',
	url: 'http://<..>/ReportServer/ReportService2010.asmx/ListChildren',
	data: {'ItemPath':'/','Recursive':false},
	complete: function(xData, status) {
		$('p').html($(xData.responseXML).text()); // result
		$("#divStatus").text( status ); // status	}
});

I got a NULL response with Status success. But where are the items?

Another test which should response only one value was that:

$.ajax({
  type: "POST",
  contentType: "text/xml; charset=utf-8",
  url: "http://<..>/ReportServer/ReportService2010.asmx/GetItemType",
  data: {"Item":"/Development"}, // Development is a Folder in my Reportserver-Root
  dataType: "xml",
  success: function (msg) {
   $("#divResult").html(msg.responseXML);
  },
        error: function (data, status, error) {
   $("#divResult").html("WebSerivce unreachable<br> <br>" + data.responseXML + "<br> <br>(" + error + ")");
  }
});

Here I got an [object Error]

And here my last test:

 var soapMessage = '<?xml version="1.0" encoding="utf-8"?>\<soap:Envelope \
       xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" \
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" \
       xmlns:xsd="http://www.w3.org/2001/XMLSchema">\<soap:Body>\<GetItemType xmlns="http://www.microsoft.com/sql/ReportingServer">\<ItemPath>/Development</ItemPath>\</GetItemType>\</soap:Body>\</soap:Envelope>';
 $.ajax({
  type: "POST",
  contentType: "text/xml; charset=utf-8",
  url: http://<..>/ReportServer/ReportService2010.asmx?wsdl,
  data: soapMessage,
  dataType: "xml",
  success: processSuccess,
  error: processError
 });

    function processSuccess(data, status, req) {
        if (status == "success")
            $("#response").text($(req.responseXML).find("Type").text());
    }

    function processError(data, status, req) {
        alert(req.responseText + " " + status);
    }

Here I got an "Undefined error"

Can anyone help me?

Thanks
