Re: AW: AW: File existence

[Olivier Billard]

try a

<map:generate src="{request-param:ID}.xml"/>
<map:serialize type="xml"/>
instead, with an "ID" param leading to a non-existing and existing file...
with a non-existing file, you should have an error telling that the file <ID>.xml does not 
exist. It should show you that the replacement is done.

you can also try to remove the "context://" from the url parameter

Well, I tried it, but the <act>....</act> part will be always ignored, no matter whether the file exists or not, I am not getting any Error messages, I think cocoon takes {request-param:ID}.xml as a file name and not the value of {request-param:ID} with the extension .xml as a file name, or am I seeing it worng?

Thanks,

My files are in the same directory like my sitemap.xmap, I do not even now how to use the Action, can you please tell me how to write my pipeline with this action?

Many thanks

Hi Halgurt...

Where do you intend to find your file ? In the root of the webapp ?

You can try
*/_    <map:when test="/{request-param:ID}.xml">_/* (add the slash)
With this, your file will be searched relatively to the context root of the webapp.
see [1].
But if your only have one resource to look for, why don't you use the ResourceExistAction, 
which is more suited to the check of one file ?
The selector is more for a set of resources... (see [1])

Hi,



I had a Problem yesterday and asked for help, I try it now again, is the 
pipeline below correct or not? I am getting an Error:

"Invalid pattern '{request-parameter}:ID�



What is a better way to check if a file exists or not? I am getting the 
file name from a request parameter.





<map:pipeline>

<map:match pattern="handling">

 <map:select type="resource-exists">

*/_    <map:when test="{request-param:ID}.xml">_/*

   <map:generate type="file" src="default.xml" />

   <map:transform type="xslt" src="form2data.xsl">

     <map:parameter name="use-request-parameters" value="true" />

   </map:transform>

   <map:transform type="write-source">

   <map:parameter name="use-request-parameters" value="true" />

   </map:transform>

   <map:transform type="xslt" src="form2html.xsl" mime-type="text/xml">

     <map:parameter name="use-request-parameters" value="true" />

   </map:transform>

  </map:when>

  <map:otherwise>

   <map:generate type="file" src="default.xml" />

   <map:transform type="xslt" src="form3data.xsl" />

  </map:otherwise>

  </map:select> 

 <map:serialize type="html" />

</map:match>

</map:pipeline>



Am I doing something wrong?



Many thanks,

Halgurt
