JBoss 5.1: jar in server lib with dependency

My war needs access to abc.jar. And abc.jar is dependent on xyz.jar. In JBoss 4.3, I was able to just put abc.jar and xyz.jar in my server lib. But in 5.1, I get a class not found exception that indicates that abc.jar can not find xyz.jar. Is there so开发者_如何学Cme new war configuration which I am missing to ensure that abc.jar can find xyz.jar?

Usually, this kind of deployment is done using EAR files, with a classpath entry in the MANIFEST.MF. I believe that a WAR should also work, provided both JARs are in WEB-INF/lib and their MANIFEST.MF is properly configured. Putting both jars in the lib probably worked before, but it was never the appropriate solution for this scenario. Your deployments should only go into deploy directory, in the form of a deployment archive.
