Title: New CocoonServlet throws NullPointerException...

Vadim, your last changes to the cocoon servlet are throwing me a NPE...

java.lang.NullPointerException

This is my sitemap, and of course, I don't have "index.xml" on the disk...

  <map:pipelines>
    <map:pipeline>
      <map:match pattern="">
        <map:redirect-to uri="index.xml"/>
      </map:match>

      <map:match pattern="*">
        <map:generate name="file" src="">         <map:serialize type="xml"/>
      </map:match>

    <map:handle-errors type="*">
      <map:serialize type="xml"/>
    </map:handle-errors>
      
    </map:pipeline>
  </map:pipelines>

Well, anyhow, this fixes it...
