Hi I see a number of google hits on loader repository and how it can be used to override the hibernate jars shipped with jboss. However, nothing I have tried convinces me that it truly works. Can some one provide a solid pointer to a sample configuration to override hibernate jars? We are using the 4.2.2 version and trying to override with 3.2.6 core hibernate and 3.3 hibernate annotation jars. Please let me know if you need more information Thanks Mike View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4204714#...
