ok thanks, but still regarding the PAR files, I'm looking at the data model, table jbpm_processdefinition, by the name I guess that's where the process files are kept. Is my guess right? Because I can't see where the classes and definition files are kept, it doesn't like the table jbpm_processdefinition can record this information. How the PAR are saved as a PAR, or the content is split to many other tables? Can your clear a bit this issue please? This is a bit important because I would probably to use the same action class to many process definitions, don't know if that ir currently possible without redundancy.
