Value-substitution question
Hi All!
I want to get the http request that will provide me the URI of the file to generate (and transform).
E.g., the request that I should get will be something like cocoon/test/xml.apache.org/cocoon/faq/faq-xslt.html
My pipeline is as following:
<map:match pattern="test/**">
<map:generate src="http://{1}" type="html"/>
<map:transform src="test.xsl" type="xslt-saxon"/>
<map:serialize type="xml"/>
</map:match>
Here is my problem:
The pipeline matches the given http request only if the URI has more than one slash, e.g., the previous example will work file, but if the http request is something like
cocoon/test/xml.apache.org/faq-xslt.html (only one slash in the given URI that is matched by the wildcard) then I get the error from Cocoon:
The requested URI "/cocoon/ub/xml.apache.org/faq-xslt.html" was not found
But I can't also use only one asterisk in the pattern match, because then I will be able to match only URI's that don't contain slashes.
So please, can you tell me what is the right pattern match for the URI with any number of slashes (zero, one or more)?
Thank you very much for help.
Anna

Thank you Konstantin.
Now I understand it, and know how to use proper matter matches.
Thank you

This is known behavior of "**" patterns. They match only paths, while "*"
pattern matches a file (no slashes in the name). I know this is not very
convinient to create two identical matchers, but as you could see from
sample sitemaps this is a usual situation and it's solved using two
matchers, one for "**" paths and one for "*". Another solution could be to
use the regexp matcher with an appropriate expression.
Try to raise this issue on dev list and probably this will be solved somehow
in future releases. (One of the possibilities could be to allow expressions
like "test/** | test/*" in patterns.)

The error isn't saying that no match occurred, but that the generator
failed. Are you certain that the resource you're trying to reach is there?
For instance, http://xml.apache.org/faq-xslt.html is non-existant, which I
would expect to give the exact error you're getting.

I thought this because of the "ub" in the error message, but if it was
only a typo ...
> Somebody can solve this mistery for me?
Yes, this seems really strange. Can you furnish proof to the contrary by
adding the matcher with pattern "test/*" after the matcher "test/**"?
Does this work? I never had such a problem with **, so I can only guess:
Isn't there any match pattern before "test/**", which catches the URI?
And what do the log files say?
As a consolation: For me everything looks ok ;-)

Re: Value-substitution question

Oh, sorry, this is my typo.
The error is of course
The requested URI "/cocoon/test/xml.apache.org/faq-xslt.html" was not found
But the problem is still the same:
** doesn't match URI "xml.apache.org/faq-xslt.html".
I can of course make two pipelines, one will match *, and the other will
match **,
but it is really strange that ** doesn't match the URI with single slash for
me.
What do you mean by "something is differently resolved, if it's only 1
slash"?
Somebody can solve this mistery for me?
Thank you very much for your help.
