Subject RE: How to set up cocoon to pass parameters?
Date Wed, 03 Oct 2001 03:53:03 GMT
There are couple of ways of achieving that.

---------------------------------------------------------------------------------------
FIRST WAY: Define (and use) transformer which would have access to ALL request parameters:
  <map:transformers default="xslt">
   ...
   <map:transformer name="xslt-with-params" src="org.apache.cocoon.transformation.TraxTransformer">
    <use-request-parameters>true</use-request-parameters>
   </map:transformer>
  </map:transformers>
  ...
>    <map:match pattern="test.html">
>     <map:generate src="testing/test.xml"/>
>     <map:transform type="xslt-with-params" src="testing/test.xsl"/>
>     <map:serialize type="html"/>	
>    </map:match>   

---------------------------------------------------------------------------------------
SECOND WAY: Use action and make only SOME request parameters available to stylesheets:
  <map:actions>
   <map:action name="request" src="org.apache.cocoon.acting.RequestParamAction"/>
  </map:actions>
  ...
>    <map:match pattern="test.html">
>     <map:generate src="testing/test.xml"/>
       <map:act type="request"> <!-- Makes all parameters accessible as {parameter-name}
-->
         <map:transform type="xslt-with-params" src="testing/test.xsl">
           <map:parameter name="paramtest" value="{paramtest}"/>
           <!-- Define stylesheet parameter "paramtest" with value taken from request parameter
"paramtest" -->
         <map:transform>
       </map:act>
>     <map:serialize type="html"/>	
>    </map:match>   


Second way is better if you care about how efficient Cocoon cache will work and if you are
planning more then
one parameter, but just some of them are required in this stylesheet.

PS: I did not tested this, might have typos ;)

PPS: You sitemap snippet is not syntaxically correct. It should read:

>    <map:match pattern="test.html">
>     <map:generate src="testing/test.xml"/>
>     <map:transform src="testing/test.xsl">
>      <map:parameter name="paramtest" value="whatever-you-want"/>
>     </map:transform>
>     <map:serialize type="html"/>	
>    </map:match>
