error handling grief

im currently trying to add error handling to one
of our publications, using this fragment:

<map:handle-errors>
  <map:aggregate element="wyona" label="gregor">
    <map:part element="cmsbody" src="docs/publication/live/wrapper.html"/>
    <map:part src="docs/publication/live/error.html" element="wrapper"/>
    <map:part src="docs/publication/live/small-preview.xml"/>
    <map:part src="docs/publication/live/sitetree.xml"/>
    <map:part src="cocoon:/today"/>
    </map:aggregate>
  <map:transform src="stylesheets/publication/Page/Live/wrapper.xsl">
    <map:parameter name="id" value="/error.html"/>
  </map:transform>
  <map:transform src="stylesheets/publication/Page/Live/images.xsl"
label="content"/>
  <map:serialize type="html"/>
</map:handle-errors>

instead of doing what it should it complains that

java.io.FileNotFoundException:
/home/gregor/build/jakarta-tomcat-4.0.6/docs/cms/access-control/identify.xsp
(No such file or directory)

any clues?
