Upload XML by Javascript (gateway problem)

Question

I am trying to upload xml and xsl files by <xml> tag or by Javascript and never can reach them because of gateway problem. Suppose i have simple portlet.jsp file and them trying to upload XML resource like this:
<xml id="source" src="source.xml" />
This is not going to work because it's not gatwayed by portal and source file never can be found. So i have tried this way
<xml id="source" SRC="<pt:url pt:href='http://.../IWSNavigation/jsp/source.xml' xmlns:pt='http://www.plumtree.com/xmlschemas/ptui/'/>"/>
But for some reason it's not gatwayed (if i do it by myself, means manual gatway this resource then all is OK, i can upload one).
I have tried to use JavaScript and failed again
var sourceUrl = "<pt:url xmlns:pt='http://www.plumtree.com/xmlschemas/ptui/' pt:href='http://.../IWSNavigation/jsp/source.xml'/>";objXMLDoc.load(sourceUrl);
Please, help me to figured out the problem. I use Plumtree v 5.0.
Thank you.

Answer 1

The gateway will always transform URLs in JavaScript which have been assigned to a location property.
So, to modify your example:
var myObj = new Object();
myObj.location = 'http://.../IWSNavigation/jsp/tree.xml';
objXMLDoc.load(myObj.location);
