Hi, I've an incomprehensible problem : I have to migrate a Tomcat/JSF/Hibernate web application using JBPM from a server to another. I use Jbpm3.1.2. The production server has many process instances launched and binded to my Object Model (in an other database). This work fine in the production environment. I dumped the two databases (the Jbpm one and my business model one) at the same time. I have exactly the same tomcat & MySQL versions on the new server. But when, after having restored the databases and lanched the apps, I can't do anything using the old processes. I just can deploy a new process (exactly the same than the old one) and use it fine. Anyone knows anything about this issue ? Thanks. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4127038#...
