All of the examples are run by Hudson using the SConstruct build file. Scons sets the environment variable ICE_CONFIG pointing to a simple configuration file like the one under etc/ice.config, which explains configuration in depth. This would also work in your case.

To put it briefly, you can get sudo.java to work by doing any of the following:
 * java sudo --Ice.Config=your_ice.config
 * ICE_CONFIG=your_ice.config java sudo
 * java sudo --omero.user=you --omero.pass=secret --omero.host=localhost
 * OR by hard-coding those values in the file itself:

        omero.client client = new omero.client("localhost");
        omero.client sudoClient = new omero.client("localhost");
        try {
            ServiceFactoryPrx sf = client.createSession("root", "ome");
            ...

Try looking at http://trac.openmicroscopy.org.uk/omero/browser/trunk/examples/OmeroClients/configuration.javafor examples of each of these methods.
