In a plugin I recently reviewed, I saw this gem:

        public static void main(String[] args) {
                try {
                        System.getProperties().list(System.err);
               System.setProperty("plugins.dir", args[0]);
                        new ImageJ();
                        IJ.run("This Plugin", "argument=value argument=value");
                } catch (Exception ex) {
                        e.printStackTrace();
        }
        }

You specify the plugin class as main class, and pass the main() method the
path to the directory containing the corresponding .class file.  Before
constructing ImageJ(), you can output anything to System.out (or
System.err).  Of course, you need to adjust the parameters of IJ.run()
appropriately.

Hth,
