Hi Arindam, 
  
  
  
Yes I am running all this in web server only did tried relative path exact path etc 
  
  
  
the issue now is  
  
If I give 
  
myChart.setDataURL("C:/../../Gantt/MyFirstChart.xml"); 
  
Then it works fine remember the data on this file is just cut and paste of the following asp's output 
  
  
  
but if I give the actual asp which generates the xml output 
  
myChart.setDataURL("C:/../../BasicDBExample.asp"); 
  
it doesn't work here(says "invalid xml data") so really confused why the direct link to asp not working 
  
  
  
if I give 
  
myChart.setDataXML("C:/../../BasicDBExample.asp"); 
  
then getting "no data to display" error message 
  
  
  
anything I am missing here. 
  
any ideas?
