Thank you Matthew for your explanation, it works fine. And your book is really the best reference for Cocoon I have seen.

Each time a component is nested inside another one we need to go "up the tree". Notice how the "resource-exists" action is nested inside the "request" action. Also notice that the Reader is inside the resource-exists action. Ok, now - the map:parameter attribute of the resource-exists action "belongs" to it - so it is at the same level and we can use "{file}" to access the parameter that the request action provides to the sitemap. The Reader is however "underneath" or "inside" the resource-exists action, so it needs to go up one step to access the same file parameter. This was the non-programmer explanation. Carsten or others can provide a perhaps more exact explanation.

The pipeline fragment is: 1. <map:pipeline> 2. <map:match pattern="download"> 3. <map:act type="request"> 4. <map:parameter name="parameters" value="true"/> 6. <map:act type="resource-exists"> 7. <map:parameter name="url" value="download/{file}"/> 8. <map:read src="download/{file}"/> 9. </map:act> 10. <map:generate src="filenotfound.xml"/> 11. <map:transform src="filenotfound2html.xsl"/> 12. <map:serialize/> 13. </map:act> 14. </map:match> 15.</map:pipeline> All seem to work except the line 8. Cocoon detect that the {file} exists (line 7) but it can't read it (line 8). It returns a HTTP error 404 (file not found). Anyone has an idea? How to check (debug) the value {file}?
