Hi there,
As you may know jBPM5 is agnostic to the type of the project that you want to build. Did you check the http://salaboy.wordpress.com/2011/01/01/emergency-service-drools-application/ application? it shows an use case where you can see jBPM5 + Drools Expert + Drools Fusion running all together. You can use jBPM5 in the same way inside a swing application and also inside a web application.
Greetings.
