I would be interested to know why as well. Maybe try adding
System.out.println()'s to your original code to show the state of the
Calendar object as you roll it?
BTW: Does anyone know where System.out's go in Tomcat 4? Are they
logged somewhere?
In general, it is better to use the object's constants than an actual
int, ie. Calendar.MONDAY instead of 2. You never know how that stuff is
specified within the class.
