Hi Manish,

JfreeChart and the underlying java2D needs a window server to run in 
order to generate its graphs.
When you're logged on your dev machine the window server is on and 
java2D can generate the graphs.
On Panther Server, the user you run your process with might not be 
logged in and your process can't access the windows
server and can't generate the graph.

To solve this add :
-Djava.awt.headless=true

to your application arguments.

It should solve your issue.
