Change the JSP file suffix _jsp programming

Today there is nothing, suddenly think of a problem, can access the suffix of JSP file to my own suffix it? After some of their own debugging, finally succeeded. Hahaha. So happy ...
First of all, configure in WEB.XM.
<servlet>
<servlet-name>testsuffix</servlet-name>
<servlet-class>mytest. Testsuffix</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>testsuffix</servlet-name>
<url-pattern>*.br</url-pattern>
</servlet-mapping>

It's OK to write a page shift in the servlet.

String uri = Request.getrequesturi ();
URI = Uri.replacefirst (". Br", ". jsp");

RequestDispatcher rd = Request.getrequestdispatcher (URI);
Rd.forward (request, response);

hahaha. You can access the previous JSP file through *.br.
