We are thinking about migrating from JBPM 3.x to 4.x.
We have an application that contains about 60 process defintions started off of a single iniitial process definition. The application was built prior to SEAM and uses JBPM 3.x to run a state machine for a web application. The process definitions deployed as part fo our EAR and are loaded from the classpath. Process Instances are retained by reference and serialized as part of user session data in a network cache. We've never hooked our JBPM 3.x installation to a database.
Does anyone know if we can do the same thing with JBPM 4.x?
