This has to be done outside jBPM e.g. with the ESB or Seam or fully custom code.
When BPMN2 is implemented on top of the PVM something might be there out of the box, maybe even for jpdl.
Can I use Mule ESB? any example or tutorial avaible?
Mule uses jBPM (3) internally. So Yes... Turotials for these should be found there. JBoss ESB also uses jBPM (3) so you can have a lookj there as well
