I have a little program that queries a web service, transforms the results using XSLT and displays them in a jQuery control. When I move the code into a web part it and deploy it, however I’m getting the following error:
The remote server returned an error: (401) Unauthorized.
This is the code that’s loading my XSLT file, which is where I suspect the problem is:
XPathDocument xPathDoc;
XsltArgumentList args;
protected override void OnPreRender(EventArgs e)
{
xPathDoc = QueryRunner.GetQueryResults();
args = QueryRunner.GetColumnsToShow();
}
public static XPathDocument GetQueryResults()
{
OpacAccess.OpacAccess proxy = new OpacAccess.OpacAccess();
string result = string.Empty;
try
{
result = proxy.query("CompanyName", "username", "password",
ReadingList=\"London\"", 1000);
}
catch (Exception ex)
{
}
// Store the xml of the result
XPathDocument xPathDoc = new XPathDocument(new StringReader(result));
return xPathDoc;
}
protected override void RenderContents(HtmlTextWriter output)
{
XslTransform xslt = new XslTransform();
// Load the xslt file and perform the transformation
xslt.Load("http://rginfonet/Style%20Library/XSL%20Style%20Sheets/Liberty.xslt");
xslt.Transform(xPathDoc, args, output, null);
output.Flush();
}
Here’s my stack trace if it’s at all helpful to anyone:

Please let me know if you can lend some insight to what’s causing this. Thanks!
The account responsible for rendering the webpart does not have access to the document library where you have the xslt located.
There are a few ways to get around this,
