In the jBPM jPDL User Guide, section "5.5. Enterprise archive"
http://docs.jboss.com/jbpm/v3/userguide/deployment.html
In the deploy directory of the downloads, you can find
jbpm-enterprise.ear. [...]
I do not find jbpm-enterprise.ear !!!!
What have you downloaded?
I can see jbpm-enterprise.ear in jbpm-jpdl-3.2.GA.zip/jbpm-jpdl-3.2.GA/deploy.
