OK, I disable cache into hibernate.cfg.xml, and when I start my server, I don't have any Exception. But I don't see the scheduler sending his messages in the console regularly :( And when I try my process, I see : 10:42:36,230 ERROR [GraphElement] action threw exception: service 'scheduler' unavailable | org.jbpm.svc.JbpmServiceException: service 'scheduler' unavailable View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4000807#...
