question about processPath() line item in ActionServlet

[Jonathan]

Gentlemen.  In the ActionServlet's processPath() method the below code exists.     processPath(HttpServletRequest request) {     .......     .......     if ((period >= 0) && (period > slash))path = path.substring(0, period);     ....... }         Shouldnt the code instead read:     if ((period >= 0) && (period > slash))path = path.substring(slash, period);
