Graphics Rendering Problem

hi,

I want to display a gantt chart using business graphics in my web dynpro application. I created the application, but on running it i get a message: <b>“Graphics Rendering Problem”.</b>I have done all the following settings:

In Visual Administrator->Server -> Services -> Configuration Adapter -> webdynpro -> sap.com -> tc_wddispwda->PropertySheetdefault, i specified the igs url. in the application UI element's property also i gave the same igs url. I also checked that the IGS is running. When i connect to http://<host>:40080 i see the IGS statistics window.

this is a web AS based IGS installation of version : 6403.0.11.5.

In the MMC also the igs watchdog is shown as running.

where have i gone wrong?

thanks n regards

Shyam.
