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

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.

Is the line 7. <map:parameter name="url" value="download/{file}"/>  is
correct?

Thank you
Sylvain

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
