java.lang.ClassNotFoundException: org.apache.cactus.server.FilterTestRedirector

Hey all,

After setting up my project to use cactus many months ago, I had to
stop integration. I recently resumed and started getting the following
exceptions from my <cactus> task:

   [cactus] StandardContext[/pantoto-2005-06-09-cactified]: Exception

I can eliminate the error and get cactus running by opening up my
cactified war file, editing the web.xml file and removing the
following:

    <filter>
        <filter-name>FilterRedirector</filter-name>
        <filter-class>org.apache.cactus.server.FilterTestRedirector</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>FilterRedirector</filter-name>
        <url-pattern>/FilterRedirector</url-pattern>
    </filter-mapping>

Two questions:
* why is this creating a problem?
* how can I keep cactus from adding these lines to my web.xml and
still use the <cactifywar> task?

Thanks, jas.
