Sample of web.xml for Servlet 2.3

Here is the sample web.xml for servers that support Servlet 2.3 only.

Notice that the ZK demo distribution has two web.xml files under the MyApp/WebContent/WEB-INF directory: web.xml (for servers supporting Servlet 2.4 or later), and web.servlet-2.3.xml (for servers supporting only Servlet 2.3). You could copy one of them instead of creating from scratch.
