I suspect that you have a stray catalina.jar file in your classpath, possibly from an installation of Tomcat. Try adding the "-verbose:class" JVM option to the JAVA_OPTS - this option will print out the location of the JAR file for each class loaded. This will help to determine if you do have a stray jar file somewhere. I don't have a Mac, so I do not know how env vars are set there, but on Windows and Linux I do NOT set a CLASSPATh environment variable. I find that doing so causes more problems than it solves.
