Creating a Process Server based on OpenSource Technologies using REST

This is a post where I will try share some thoughts about where REST could be useful inside a SOA architecture using Business Process Management, in that case we will be using jBPM and RESTEasy, which is the JBoss's implementation for JSR311 - Java Restful WebServices.

Thanks for the audience at TS 4721 in JavaOne

First of all, thank you everyone for being present at our session TS4721, I took some pictures of you guys (almost 1700 people) to prove to my boss why it is really important to speak at JavaOne. Of course it is a joke, my boss really knows how important it is.
