[jbpm-dev] new blog post about processes and rules integration

Sat Aug 4 07:44:23 EDT 2012

Totally agree with having downloadable projects..
We need a quick way to transform a test into a fully distributable project,
any Ideas? Archetypes is the way to go in my opinion, but if I start doing
that It will slow my blog posting productivity :) I need some help please!
