Kristin,
From my understanding you are using RAP as front end of jBPM through
which you can start process instances, execute tasks etc and you want to
be able to track process execution progress which is reflected by which
state/task node is currently highlighted. I think jBPM has similiar
console and you can peek at the source to see how it's implemented.
Regards,
Setya

Hi Kristin,
I guess you want to draw on an image on the server, right? You could use
AWT graphics or any image drawing library to do so, but note that for
this to work, you might need to have an X-Server installed at
deployment. With AWT graphics, some operations even work without X, you
have to specify the java.awt.headless=true option. See [1] for details.
Hope that helps,
Ralf
