Sure.... :-)
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>
This has to do with the nesting of components. 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.

Thank you Matthew, but could you explain why!?
Is the line 7. <map:parameter name="url" value="download/{file}"/> is
correct?
Thank you

Hi,
guess what - this is a bug in the book :).
>>
8. <map:read src="download/{file}"/>

That line should read:
<map:read src="download/{../file}"/>

Subject: example in the Cocoon book
Hello,
I'm reading the Cocoon book written by Matthew and Carsten and one example
in it doesn't work.
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}?
Thank you
Sylvain
