Hi glad that helped a bit :) ., regarding the problem you encounter, there might be an issue with connection to in-memory H2 instance from different JVM, Try to deploy your app as EJB module to see if it works, or you can configure jbpm to use different DB - I saw a post on the forum explaining the necessary steps(you probably have to modify the config files in jbpm-installer/db and re-run the ant install.demo)
