Here is a class that launches a jar file I had lying around on my PC:

class Executor {
	public static void main(String[] args) {
		Runtime r = Runtime.getRuntime();
		try {
			r.exec("javaw -jar e:\\java\\projects\\McTest.jar");
			System.out.println("done it!");
		}
		catch (java.io.IOException ioe) {
			System.out.println("IO Exception:" + ioe);
		}
	}
}
