Thanks Tihomir!
That's all the informmation I was looking for :-).
I'm happy I was finally able to be clear enough about my intention when I first posted the questions I posted.
Be sure as soon as jBPM 6 is released I'll start testing and posting issues as I found them. Meanwhile I got forced to postpone jBPM integration but I'm more than whiling to contribute as you're surely whiling to provide information, feedback and help when requested.
Any hint about jbpm6 release date?
Thanks again,
Guillermo
