Parameters between Action and XSP

[Carlos Duque <cd...@eic.es>]

Hello, I'm developing a application under cocoon. My question is to mark a "best practices" in my work. 
How I pass parameters between Action and XSP? Which are the best option?
I know:
    -session
    -request.setParameter
It's possible with Map returned? with response?
 
Thank's for all!!

I would recommend the following:

public Map act(...) {
     ...
     Map result = new HashMap();
     result.put("foo", value);
     return result;
}


<map:act type="...">
   <map:generate type="xsp" src="...">
     <map:parameter name="foo" value="{foo}"/>
   </map:generate>
</map:act>


XSP: String foo = parameters.getParameter(foo);


This way you have a separation between parameter names in action
and XSP and see what happens in the sitemap.
