servlet filter mapping overlap

I have two filters. And the url-pattern are respectively:

<filter>
    <filter-name>ListFilter</filter-name>
    <filter-class>mypackage.ListFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>ListFilter</filter-name>
    <url-pattern>/list.jsp</url-pattern>
</filter-mapping>

<filter>
    <filter-name>AllFilter</filter-name>
    <filter-class>mypackage.servlet.AllFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>AllFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

Then how will the two filters work if user access list.jsp?

All filters will get applied, in the order they are defined in web.xml.

For servlets, obviously only one can be executed, and this will be the most specific match.
