Help needed with sending XML data out of Dashboard design/ Xcelsius

Question

Hi All,
I did this a year back and got it right, but now am not able to get it, probably Ive made a small mistake which I have been overlooking.
I selcted Enable XML send in my XML data connection and dfined the connection name as "Range_1" and Range name also as "Range_1"
Now I worte this servlet in Java:
public class PostTestServlet extends HttpServlet{
     protected void doPost(HttpServletRequest request, HttpServletResponse response){
     String param1=request.getParameter("Range_1");
     System.out.println(param1);
     protected void doGet(HttpServletRequest request, HttpServletResponse response){
     System.out.println("Get Called");
     doPost(request,response);
     System.out.println("abcd");
Deployed it to Apache Tomcat 6.
Also selected the required usage options in Xcelsius for sending data every 10 seconds.
Now the servlet gets called, I see it in the console.
But the request.getParameter("Range_1") is returning null.
Tried many things, not able to figure it out. Any help?
Thanks
Nikhil

Hi,
Xcelsius/Dashboards will convert the range of values that you want to send into XML.
It then will POST the XML when it calls the web page.
For example, if you had created three ranges to send to your web page:
A (a single cell)
B (a single cell)
C (a row of three cells)
The data in the POST input stream for the web page will look something like this:
<data>
  <variable name="A">
    <row>
      <column>10</column>
    </row>
  </variable>
  <variable name="B">
    <row>
      <column>15</column>
    </row>
  </variable>
  <variable name="C">
    <row>
      <column>1</column>
      <column>2</column>
      <column>3</column>
    </row>
  </variable>
</data>
I don't have an example for ASP, but I do for a JSP (attached).
