Maybe you're right, I may have missed what the intent was. But if the
question is "how do I get the URL used to request the JSP page", then
the answer is actually getRequestURI. For a JSP page, the JSP processor
is mapped to the .jsp extension so getPathInfo and getPathInfoTranslated
returns null. See JSP 1.0 Appendix B for details.
