I agree with the first response - many of the "advanced" things in jBPM are really customizations/extensions that are revealed as you read the user guide and come to understand the possibilities. for example we've built: emailing on task assignment that is configurable at runtime (not based on a process definition) a really flexible form generation and input validation system much better handling of group assigned tasks for long running processes several other extension points that are hinted at and available by seeing how embeddable and extensible the engine really is... so the question stands - what do you want to do? is there some capability you're wondering if jBPM has/can be made to support, or is this just a general question? If the latter, I understand. We've done most of the interesting things through trial and error, testing, reading and re-reading the guides, and the best guide of all, the source. jBPM builds easy, and if you pull down the source you can plug it right into eclipse for debugging whilst you're working. If the former, you'll have to be more specific. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3969031#...
