Subject spaces in request-param
Date Tue, 21 Sep 2004 12:11:37 GMT
Greetings

I'm trying to solve a problem that I think is a very basic functionality.  I
simply cannot believe there are no way to do this, but after 2 days googling
aroung,. I still don't find a solution to this.

I'm trying to pass request-parameter that contains spaces to a generator ,
using this pipeline:

<map:pipeline>
 <map:match pattern="gazetteer">
    <map:generate type="file"
src="http://cgdi-dev.geoconnections.org/cgi-bin/prototypes/cgdigaz/cgdigaz.c
gi?version=1.0&amp;request=GetPlacenameGeometry&amp;geomtype=bbox&amp;PLACEN
AME={raw-request-param:PLACE}"/>
     <map:transform type="xslt" src="style/gaz_result.xslt"/>
     <map:serialize type="html"/>
 </map:match>
</map:pipeline>

This works fine with a single word (such as 'Toronto') but fails with a name
containing a space (eg. 'Black River' or Black%20River or Black+River)

I get a org.apache.cocoon.ProcessingException: Failed to execute pipeline.:
java.io.IOException 

The exception stacks starts with

Original Exception: java.io.IOException

and somewhere down this impressive list I see

Of course, if I copy this URL
(http://cgdi-dev.geoconnections.org/cgi-bin/prototypes/cgdigaz/cgdigaz.cgi?v
ersion=1.0&request=GetPlacenameGeometry&geomtype=bbox&PLACENAME=Black
River)and copy it in a browser, it works fine

I get the same exception wheter I use %20 or +, etc..

Any clue ?  Sorry if I missed something obvious but I search and did not
find anything.  I can't believe I'm the only one passing parameters with
spaces in the whole cocoon community ! 


Cheers and thanks
