JBPM want a definition of ernie but I'm not in this node yet for executing I just create my start node. can you help me ?

I want create a java file which permit me to create all the possible processes like the webapplication of the quickstart, (in a portlet). for the moment I can create a porcess if my start task in assign by swimlane to a specific person. So I want to generalize file to create any processes that I want to.
