Hi Ronald, Shame on me that I did not search in JIRA before but I was absolutely convinced it's my fault and not jBPM's one. However, I cannot find anything related in JIRA. Yesterday I removed the cycles in the process definition because I was not sure about them but they should be no problem. I examined my Tomcat logs and finally found that the decision handlers used in the process definition cannot be found. So maybe the error message is just misleading. | org.jbpm.pvm.internal.wire.WireException: couldn't create object: couldn't load class AuthorityChecker | AuthorityChecker is the implementation for one of my decision nodes in my process definition. There is an ant script to deploy a process and its classes to JBoss. Right now I am using the ant task to deploy my process to Tomcat. Is there such a place like userlibs on JBoss? Where to put the created jar with the decision handler classes and further ones (like for java nodes).
