If not, maybe this will help you, else maybe you could help me :) (you could see my post http://community.jboss.org/thread/151046 here)... I'm getting a similar error, in the same line, calling the same method... but in my case I'm loading a jpdl.xml and the class cast it's different, throwing a similar error: java.lang.ClassCastException: org.jbpm.jpdl.internal.model.JpdlProcessDefinition cannot be cast to org.jbpm.pvm.internal.model.ProcessDefinitionImpl To be more exact, in my code the cast is from JpdlProcessDefinition to *org.jbpm.pvm.internal.model.*ProcessDefinitionImpl, ubicated in a different package from yours. Your package doesn't exist in the jbpm.jar distributable of version 4.3 (I supose this package existed in the version you used). Any help would be appreciated. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/539478#539478] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
