The hibernate.cfg.xml should be at the root of the application, the same place where your hibernate.properties was present earlier. Is your application an ear or a war file. If so can you post the output after following the steps below: - Open a command prompt - From the command prompt move to %JBOSS_HOME%/server/default/deploy - Run the following command: jar -tf myApp.war where myApp.war is the name of your application. Post the output. The output will display the contents of your application. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4050376#...
