I know that it is not using my 3.6.0 version of Hibernate because 1) the Hibernate log messages indicate 3.3.1 as well as failing because the Slf4j fails with an error indicating that 1.6.1 (the jar I am using) is not compatible with the 1.5.5. binding (the one in JBoss 5.1.0GA) and 2) because Hibernate can not start due to a "NoMethodException" that it is not thrown when I run my app outside of JBoss. My deployment characteristics require that I use solely JBoss 5.1.0GA and no other version (younger or older for that matter). Anyway, the problem now as you might notice from my initial post is that whenever I use the jboss-classloading.xml file I get those errors, so if I am to follow your advice it won;t work as it currently fails. Any idea what causes this failure using the jboss-classloading.xml file? 14:35:42,336 ERROR [AbstractKernelController] Error installing to Instantiated: name=jboss.jacc:id="vfszip:/D:/java/containers/jboss-5.1.0.GA/server/default/deploy/pnsgdp.war/",service=jacc state=Described mode=Manual requiredState=Configured java.lang.ClassNotFoundException: org.jboss.deployment.security.WarJaccPolicy from Thanks -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/573892#573892] Start a new discussion in JBoss Microcontainer at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
