    Thanks, it works!

    using getResourceAsStream instead of getSystemResourceAsStream and updating
    path to absolute path (starting with a /) both way (within eclipse and from
    command line) works :-)

    Thanks for the support,

    Frederic

    WOBootstrap is what WO 5.2 uses for launching WO Apps. You might be better
    off rewriting the code below:

    com.bar.foo.TheClass.class.getClassLoader().getResourceAsStream("mypack/file
    .xml");

    (off the top of my head). getSystemResourceAsStream()locates the resource
    through the system class loader (see getSystemClassLoader()). That is
    probably above the WOBootstrap classloader and hence the resource cannot be
    located.
