Hey Mauricio,
Thanks for your response. I use Eclipse for the Java development piece, so I needed to understand how it worked in that IDE, though it will eventually be used in the Web Process Designer and JBPM Console. Your answer helps some, but I needed to understand what to do in the Java work item code. I found a post on StackOverflow (http://stackoverflow.com/questions/9433776/jbpm-how-to-get-workitemhandler-results) that provided some hints no how to return the results in the work item so they can be used in the next service task.
