no servlet mapping? my app dead

[Kucera, Rich]

This code used to work under 0.8.0,  but not under 0.8.1.  I get a 404:

        <servlet-mapping>
                <servlet-name>snoop</servlet-name>
                <url-pattern>/snoopy</url-pattern>
        </servlet-mapping>

My app depends on this kind of mapping,  Is there a new rule or a
workaround?
TIA
