All Jopr distros should have come pre-licensed - there should be no "licensing restrictions" in Jopr.
Look in the jbossas/server/default/deploy/rhq.ear/license directory and you should see a license.xml.
Did the machine you installed Jopr on also have (or had) a copy of JBoss ON?
Thanks for ur reply. now its working fine. i think it may be a issue related to db user.
