Hi, I deploy the hibernate related configuration files in .har file and few of the classes which are part of .har are also part of .war file. When I tried to cast few classes which are returned by hibernate and loaded by both class loaders , I ended up with classcastexception. Can anyone share experience on how to handle this? Can I force the server to use only use classes loaded by one loader instead of both? Thanks Sun View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4071369#...
