Hi folks, I was asked by Dimitris to initiate this forum thread. The problem I'd like to talk about is described here: http://jira.jboss.com/jira/browse/JBAS-5115 In short: I've got correct AS 4.x DD with the following content: <?xml version='1.0' encoding='UTF-8' ?> | | <!DOCTYPE jboss-app | PUBLIC "-//JBoss//DTD J2EE Application 1.4//EN" | "http://www.jboss.org/j2ee/dtd/jboss-app_4_0.dtd"> | | <jboss-app> | <module-order>strict</module-order> | </jboss-app> | Archive with such jboss-app.xml file works very well on AS 4.x but fails on AS 5.x with the exception (available in aforementioned bug). From my point of view it's backward compatibility issue.
