Jquery: get xml from the web service

Trying to get xml from the web service:

 $.ajax({
                type: "GET",
                url: 'http://77.65.139.254:10000/_layouts/SPWebService/SPService.asmx/GetFileContentByUrl',
                data: { fileUrl: 'Accounts/8b077249-98bb-e011-926f-00155d000e46/EVTemplates/FEFCO0200/FEFCO%200203_3D.JPG' },                
                dataType: 'text/xml',
                success: function (html) {
开发者_运维问答                    alert('yes');
                }
            });

the result is: XML Parsing Error: no element found Location: moz-nullprincipal:{1f083902-dc6e-4e0b-a18e-4aa1ab99ff56} Line Number 1, Column 1:

my request looks like:

Host    77.65.139.254:10000
User-Agent  Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0.2) Gecko/20100101 Firefox/6.0.2

When I insert the link in the browser - it works ok - returns xml. the request (valid) looks like:

GET /_layouts/SPWebService/SPService.asmx/GetFileContentByUrl?fileUrl=Accounts/8b077249-98bb-e011-926f-00155d000e46/EVTemplates/FEFCO0200/FEFCO%200203_3D.JPG HTTP/1.1

What is wrong with my jquery get?

You'll need to proxy the XML request. Make the Cross-domain from backend and echo it locally.
