  1. First Entry of the First Iterator
  2. Second Entry of the First Iterator
  3. Third Entry of the First Iterator
  4. First Entry of the Second Iterator
  5. Second Entry of the Second Iterator
  6. Third Entry of the Second Iterator
  7. First Entry of the Third Iterator
  8. Second Entry of the Third Iterator
  9. Third Entry of the Third ITerator

  private List myList3;


  public String execute() throws Exception {

      myList1 = new ArrayList();
      myList1.add("1");
      myList1.add("2");
      myList1.add("3");

      myList2 = new ArrayList();
      myList2.add("a");
      myList2.add("b");
      myList2.add("c");

      myList3 = new ArrayList();
      myList3.add("A");
      myList3.add("B");
      myList3.add("C");

      return "done";
  }

  public List getMyList1() { return myList1; }
  public List getMyList2() { return myList2; }
  public List getMyList3() { return myList3; }
}
