Usage

From source file:Main.java

public static void main(String... args) {
    try {//  w  w  w.  jav  a 2  s .  c o m
        Class<?> c = Class.forName(args[0]);
        Class[] argTypes = new Class[] { String[].class };
        Method main = c.getDeclaredMethod("main", argTypes);
        String[] mainArgs = Arrays.copyOfRange(args, 1, args.length);
        System.out.format("invoking %s.main()%n", c.getName());
        main.invoke(null, (Object) mainArgs);

        // production code should handle these exceptions more gracefully
    } catch (ClassNotFoundException x) {
        x.printStackTrace();
    } catch (NoSuchMethodException x) {
