/ urlpage和urlpage有什么区别？

Question

I can't understand why sometimes a '/urlpage' is used over a simple 'urlpage'.

for example on a form,

<form action="TestServlet">

<form action="/TestServlet">

I want to understand what is the proper way of specifying a path to a html, servlet, jsp, jsf and etc.

Answer 1

The first one is relative to the current path. For example, if you are on /appcontext/abc/def/Something, TestServlet will be on /appcontext/abc/def/TestServlet

In the second one, it is relative to the context of your app: if you are on /appcontext/abc/def/Something, /TestServlet will be on /appcontext/TestServlet
