    Hi Roy,

    This looks like a nested ClassLoader issue recently discussed on the
    list -
    http://objectstyle.org/cayenne/lists/cayenne-user/2004/07/0047.html

    The solution is either load cayenne.jar using the same class loader as
    the one used for the application classes (in case of web app, this
    simply means putting cayenne.jar in the web app WEB-INF/lib/
    directory), or bootstrap cayenne with appropriate class loader
    explicitly:

    Configuration.bootstrapSharedConfiguration(iiv_test.SiteDailySum);

    The first solution is cleaner, but you don't always have a choice...
