My web.xml
:
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
The <servlet-name>
of the <servlet-mapping>
entry must be exactly the same as the <servlet-name>
of the <servlet>
entry.
So, in your specific case, change this line in <servlet-mapping>
entry
<servlet-name>dispatcher</servlet-name>
to
<servlet-name>DispatcherServlet</servlet-name>
