RE: Beginner questions

[Michael Hedgpeth <mh...@indemnimed.com>]

Could someone you give me a simple example of a bean being declared in the
Action class that IS NOT an ActionForm and then accessed in the JSP
<bean:write .../> tag?  The ActionForm maintenance seems to be pretty
straight-forward, but I'm dealing with plenty of objects that don't directly
relate to forms (such as summary data) that I would like to pull up in the
Action class and set so the <bean:write .../> can access it (in a report
format).

Thanks,
Michael Hedgpeth

The Struts bean tags do not require the useBean read tape, and it is
rare for a Struts application to ever need to do this :) 

Struts is designed to encourage architectures based on the MVC paradigm.
Generally, we recommend that all the beans be created and properties set
by an Action object (org.apache.struts.Action) before forwarding control
the presentation page. The page should just be outputing data, and
shouldn't to do any additional processing. That's the Action's job :)

Just instantiate the bean, place it the request under a known name, and
then use that same name on the other side. 

 ResultBean result = new ResultBean();

// ...

 request.setAttribute("RESULT",result);


<bean:write name="RESULT" property=" ... />
