No mapping for [..] in DispatcherServlet with name '...'

[Tobia]

Hello I have some troubles with a simple webapp in eclipse/tomcat.
I report here my files:

WEB.XML

  <display-name>TestWeb</display-name>
  
  <servlet>
    <servlet-name>testweb</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value></param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  
  <servlet-mapping>
    <servlet-name>testweb</servlet-name>
    <url-pattern>*.ctrl</url-pattern>
  </servlet-mapping>
  
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
  </welcome-file-list>

TESTWEB-SERVLET.XML

<beans>
    <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <props>
                <prop key="/test.ctrl">TestController</prop>
            </props>
        </property>
    </bean>   
    <bean id = "TestController" class="TestController" />   
</beans>

when i start the server, everything works, but when i request test.ctrl the server console writes:
- No mapping for [/TestWeb/test.ctrl] in DispatcherServlet with name 'testweb'

Why?
thanks
