access ResultList object - helper bean - downstream (ARTIMUS)

[douglas reames]

Morning all,
I am attempting to extend ARTIMUS to see how I might 'architect' a struts 
app that gives the user output alternatives:  wap, excel spreadsheet, pdf... 
 The ActionMapping (comes straight from the ARTIMUS mapping for RenderRss) 
IS:

<!-- Render an article as PDF file -->
   <action
       path="/pdf/Article"
       type="org.apache.struts.scaffold.ProcessAction"
       parameter="org.apache.artimus.article.FindByArticle"
       name="articleForm"
       scope="request"
       validate="false">
      <forward
           name="success"
           path="/do/pdf/Render"/>
   </action>
   <!-- Render result as PDF file -->
   <action
       path="/pdf/Render"
       type="org.apache.artimus.struts.RenderPdfRms"/>


[1] How do I save a helper bean ( with sql query results for an article ) , 
so that it can be subsequently retrieved downstream by the RenderAction?

For those familiar with ARTIMUS, it would be most helpful if you responded 
with its workflow in mind:
OUT:  ProcessAction-> ProcessBean -> AccessBase -> DataBase
IN:  AccessBase -> ProcessResult -> ProcessBean -> ProcessAction



[2] Does it matter  - architecturally OR practically -whether it is saved as 
a org.apache.commons.scaffold.util.ProcessBeanBase  or 
org.apache.commons.scaffold.util.ResultList ?



NOTE:  when I attempt to follow the ARTIMUS::RenderRss::executeLogic method 
code - I presummed ( probably incorrectly ) that the value for 
'Tokens.LIST_KEY' was being set by struts "under the hood":

ResultList result  = (ResultList) request.getAttribute(Tokens.LIST_KEY);

"result" is Null

Thank you for your time.
