I am in the process of migrating webservices deployed in JBoss 4.2.1 to JBoss EAP 5.1.0. In my case an EJB is exposed as a webservice. Is JBoss EAP 5.1.0 backward compatible with webservices deployed in 4.2.1 or are there any deployment changes I need to make. Is webservice deployment different in EAP 5.1.0 ? I sincerely appreciate suggestions in this regard.
