This month, Packt Publishing is going to publish the book "jBPM Developer Guide" of Mauricio Salatino which is expert in jBPM, JBoss and J2EE technologies.
This book looks very interesting and Packt Publishing has asked to me for reviewing such a book on this month. I'm pleased to review it since I already worked a bit with jBPM+JBoss some time ago, and I'll be posting my review sooner on February 2010.
Here there is a sample chapter (Getting your Hands Dirty with jPDL) available for free. Enjoy it!
