XML return (java - struts) to GridObject...

Hello friend,

is possible dhtmlXGridObject catch a XML return through Action Struts (like a response.getWriter() - Java)?

example:

my page (jsp):

...
<script>
var mygrid;
function doInitGrid(){
mygrid = new dhtmlXGridObject('mygrid_container');
mygrid.setImagePath("<%=request.getContextPath()%>/scripts/imgs/");
mygrid.setHeader("Test1,Test2,Test3,Test4");
mygrid.setInitWidths("*,100,100,100");
mygrid.setColAlign("left,center,center,center")
mygrid.setSkin("light");
mygrid.setColTypes("ro,price,price,price");

mygrid.init();
mygrid.clearAll();
mygrid.loadXML("/webcalculator/calculator.do?action=buildXMLGrid");
}
</script>
...

My action Struts:

...
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.output.XMLOutputter;

...
// Important: I´m using Jdom to generate XML
public ActionForward buildXMLGrid(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        
try{
    List nodes = new ArrayList();

    // Important: I´m using Jdom to generate XML
    Element rows = new Element("rows");
    Element row = new Element("row");
    Element cell = new Element("cell");
    
    for (Integer a = 0 ; a <=3 ; a++){
        nodes.add(new Element("cell").setText(a.toString()));
    }
    
    cell.setChildren(nodes);
    
    row.addContent(cell);
    rows.addContent(row);
    
    Document doc = new Document();
    doc.setRootElement(rows);
    
    //Imptrimindo o XML
    XMLOutputter xout = new XMLOutputter(" ", true);
    xout.setEncoding("iso-8859-1");
    xout.output(doc, System.out);
    
    response.setContentType("text/xml; charset=iso-8859-1");
    response.setHeader("Cache-Control", "no-store, max-age=0, no-cache, must-revalidate");
    response.addHeader("Cache-Control", "post-check=0, pre-check=0");
    response.setHeader("Pragma", "no-cache");
    
    PrintWriter out = response.getWriter();
    out.print(xout);    
    out.close();
    
    return null;
    
} catch (Exception e){            
    return null;
}

Yes, it possible , while response contains valid XML data and sent with valid headers - it is not difference is data as static XML file or generated by any kind of server side script.
As far as I can see provided code is correct.
If , by any chance, you still get "Incorrect XML" message - please check
