Query Problem in GUI..

[Shuch]

Hi all,
I m trying to make a java GUI that can insert,query,delete documents…insertion and deletion works fine but whenever i m trying to run query procedure as follow:
public static void performQueryAndListSerials(TXMLObjectAccessor accessor, TQuery query) throws TException {

     Result_Frame rf = new Result_Frame();
     rf.show(true);
     String i;

    try  {
       TResponse response = accessor.query( query );
       TXMLObjectIterator iterator = response.getXMLObjectIterator();
      rf.jLabel2.setText( "The query \"" + query + "\" returns " );
      if (!iterator.hasNext()) {
          rf.area.append( "no documents!" );
         } else {
           i = performCountQuery(accessor,query);
            rf.jLabel1.setText( performCountQuery( accessor, query ) + " documents, which are:" );
        //rf.jLabel4.setText(i);

   while (iterator.hasNext()) {
        TXMLObject xmlObject = iterator.next();
         rf.area.append( "  " );
       // printSerial(xmlObject,rf);
       Element e = (Element)xmlObject.getElement();
     String NAME = getDOMElementTextByTagShow(e, "NAME");
      String START_TIME= getDOMElementTextByTagShow(e, "START_TIME");
     rf.jLabel1.setText(" The Inserted document is as follow:  \n");
      rf.area.append(NAME + " ,  " + START_TIME+ "ino:id=\"" + xmlObject.getId() +"\n collection=\"" + xmlObject.getCollection() + "doctype=\"" + xmlObject.getDoctype() +"\" " );

        }
      }
    }
    catch (TQueryException queryException)  {
      showAccessFailure( queryException );
      throw queryException;
    }

}

// utility method to retrieve text of an element specified by its tag from a DOM tree
public static String getDOMElementTextByTagShow(Element element, String tagname) {
NodeList nl = element.getElementsByTagName(tagname);
Node n;
n = nl.item(0);
n = n.getFirstChild();
return n.getNodeValue();
}

according to the quoted area it should print the names and start time of the serials whenever the query runs…but unfortunately it just shows the number of serials n thats all…I m attaching the screen-shot with this…
thanks in advance,
