Hi Mauricio,
The only reason actually I asked for a complete application is because Jbpm is a little more complex to get started with as compared to traditional frameworks like spring, hibernate etc. Most new versions for projects have demo web applications so that the user is helped to get started with and also it's very important to have a simplistic beginner's guide to build a healthy community of developers around the product but my experience with JBPM hasn't been good at all as the documentation and examples are highly inadequate and thus discouraging developers to explore JBPM and integrate it into their software solutions.
