Hi all, Is it only me, or every body else know how to get around this ? Heres my situation: I dont want to use hibernate jars which comes in Jboss4.2.2 distribution. These jars are old (3.2.1). I want to use the latest version with Jboss4.2.2. I tried keeping my ear file isolated using the tag in ear-deployer.xml. But I am getting the classic ClassCastException. Somehow Jboss always wants to use its version of hibernate jar files. Any help is highly appreciated !! thanks Anil.
