Add this to the deployers/metadata-deployer-jboss-beans.xml (under the JBossMetaData section) <!-- JBossMetaData -->: | | <entry> | <key>jboss_5_1.xsd</key> | <value>org.jboss.metadata.ejb.jboss.JBoss50MetaData</value> | </entry> And please do open a new thread in JBoss AS5 forum http://www.jboss.org/index.html?module=bb&op=viewforum&f=287 with reference to this thread, so that it comes to the notice of the dev team.
