Mapping 2 or more URL patterns with same servlet

We have a simple Spring MVC servlet (as usual), nothing out of normal. <servlet> <description>The framework will, on initialization of a DispatcherServlet, look for a file named [servlet-name]-servlet.xml (webApplicationContext-servlet.xml) in WEB-INF</description> <servlet-name>webApplicationContext</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/conf/spring/webApplicationContext.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet>
With its respective mapping <servlet-mapping> <servlet-name>webApplicationContext</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping>
This is the tricky part, I want to map some weird request mappings like: *.htm or *.jspx (besides *.do)

• registerCustomer.do
• registerCustomer.htm
• registerCustomer.jspx

The solution is simple, just add another entry to your servlet-mapping: <servlet-mapping> <servlet-name>webApplicationContext</servlet-name> <url-pattern>*.do</url-pattern> <url-pattern>*.htm</url-pattern> </servlet-mapping> The only restriction is to use web-app version=2.4 or 2.5
I always use 2.4 and I didn't have anything else to do. But for educational purposes I updated my web.xml (web app descriptor) for my future developments.
