These are just warnings issued by Hibernate. You can safely ignore them (they should be removed from newer version of Hibernate). See: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2795 If you don't want to see them anymore, please edit the jboss-log4j.xml file in your AS configuration conf directory: <!-- Hibernate got a bit too verbose in JBoss AS 4.2.1.GA --> | <category name="org.hibernate.engine.loading.LoadContexts"> | <priority value="ERROR"/> | </category> | | <!-- JBoss Cache likes to talk a lot --> | <category name="org.jboss.cache.interceptors.CacheLoaderInterceptor"> | <priority value="ERROR"/> | </category> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4094814#...
