Yes, I am running under IBM Websphere application server. Can you further explain what you mean by "same place as my code"? Now the jcs jar is in a different directory and I have set up the dependencies (class-path in the MANIFEST.MF) so that my application can find the jar files. I can move them to /WEB-INF/lib and see if that makes a difference, is that what you suggest?
