I have the same question. I'm trying to migrate some customers using Glassfish/BPEL to JBoss/jBPM. Having BPEL support in JBoss is important for the migration. In the long run we want to move everyone to BPMN so I want to start with jBPM v4 which is the first version to support BPMN. However, when I try deploying the BPEL ear to JBoss 5.1 (required by jbpm 4) I get this error: org.jboss.xb.binding.JBossXBRuntimeException: Element {http://java.sun.com/xml/ns/j2ee}application is not bound as a global element.
