    Chris,

    The only error I see is that strictly speaking "-Xmx400mb" should be "-Xmx400m",
    but I fail to see how that could affect JIT settings. The only way I know in JDK1.3
    to turn of the JIT is with the option -Xint. By default the client HotSpot JIT is
    active.

    All this is of course about the Sun JRE. I think you use the one from IBM. Could you
    therefore send the usage string of the java command?

    Werner.
