UnnamedSelector: ComponentSelector could not find the component for hint

[Frank Wulf]

Hi,   I'm new to Cocoon and trying to develop a little cocoon serializer to convert xml-data to binary output. However cocoon gives me the following error message:   type fatal message UnnamedSelector: ComponentSelector could not find the component for hint: testser description org.apache.avalon.framework.component.ComponentException: UnnamedSelector: ComponentSelector could not find the component for hint: testser sender org.apache.cocoon.servlet.CocoonServlet source Cocoon servlet Any hint where to search for this error? My sitemap.xmap entries are: <map:serializer mime-type="application/octet-stream" name="testser" src=""/> .... <map:pipeline>    <map:match pattern="serializer_test">      <map:generate src=""/>      <map:serialize type="testser"/>    </map:match> </map:pipeline> I looked through all the Serializer-code examples but got no clue so far. Thanks, Frank Wulf
