Hi,

I'm having some trouble while running my jBPM project on jboss 5. Just before the server starts, I get an error:

DEPLOYMENTS IN ERROR:
     Deployment "persistence.unit:unitName=myProj.ear/#BPM-DB" is in error due to the following reason(s): java.lang.ClassNotFoundException: org.jbpm.persistence.ProcessInstanceInfo from BaseClassLoader{jboss_project_path/jboss-service.xml}

I really can't understand why this happens, since I have the orm.xml, persistence.xml and ProcessInstanceInfo.hbm.xml. Can anyone help me with this? Google has not been my friend on this subject.
