I did STFI and RTFM, still i could'nt find it.
I found this link in the getting started guide:
but it redirects to the main jbpm project page.
Also, when you go to the canonical
page, jbpm is not listed.
To think that i was just one click away, in the subprojects section... :-$
So it's a bit confusing. Luckily there is a friendly community :-)
Yes, sometimes old docs dangling somewhere can be misleading
