    Hey, problem has just been solved. It was an interesting problem; the
    java that comes with fedora core linux is different to Sun's java, and
    not fully compatible with every java application. The solution is to use
    JPackage to run 2 versions of java simultaneously (2 'alternatives').
    Thanks,
    Jack
