I can't get SimpleMappingExceptionResolver work the way I want

I am using spring 3 and I tried to add exception mapping this way:

<bean
        class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
        <property name="exceptionMappings">
            <map>
                <entry key="it.jsoftware.jacciseweb.controllers.AcciseAuthException" value="/jsp/errorUserPage.jsp" />              
            </map>
        </property>     
    </bean>

of course jsp(s) are NOT in WEB-INF but in a folder in the root called jsp. What I get is my custom page for 404 handling, that I configured in web.xml. What's wrong?

Here is Spring log with DEBUG enabled:

UPDATE

I'm adding this for who'll see this question in the future. This configuration is OK, the JSP was just wrong. Thanks anyway to the answer that proposes a better method to handle this is Spring 3.

Did you mean to have .jsp in the exception value? How are your controllers and view resolvers etc set up? Do they append a .jsp to the value before resolving paths etc?

Do you need to have the exception mapping in xml? Could the @ExceptionHandler annotation fullfill your expectations?

Here is a nice example of xml based spring exception resolvers (although spring 2.5 based): http://developingdeveloper.wordpress.com/2008/03/09/handling-exceptions-in-spring-mvc-part-2/

Do note if you go the annotation way that the annotations methods needs to be within the same controller class (or abstract class). I wrote a small example of this: http://blog.flurdy.com/2010/07/spring-mvc-exceptionhandler-needs-to-be.html
