Its available only in jboss.xml. Could you point us to the doc which says that its available in ejb-jar.xml? We'll fix it. The new tutorials for AS-5 are here http://www.jboss.org/jbossejb3/docs/ Specifically, the @Service using deployment descriptors http://www.jboss.org/file-access/default/members/jbossejb3/freezone/docs/... The env-entry can be specified for the services in the jboss.xml. If that doesn't work then please post the contents of your jboss.xml and the entire exception stacktrace. While posting logs or xml content or code, please remember to wrap it in a code block by using the Code button in the message editor window.
