Hi,
I'm facing a lot of problems trying to maintain the
extra path info in the URL. Few of these problems I've
managed to work around by overriding methods in the
base classes, specially ActionServlet class. The
current problem that I have has to do with Form Tags.
Lemme tell you the scenario
It's a little difficult without seeing your implementation of validate(),
your MessageResources bundle, the input property for your ActionMapping, and
whatever custom taglib code you've implemented for handling the display in
xyz.jsp.
And while you're at it,
You would do it the way you'd do it an any web application.
Here's how I do it: All my button field names start with btn. I would
name these buttons btnProcess, btnViewByOrg and btnViewByProcess (or
something similar).
In my perform method, I'd put code like this:
String button_pressed
Name the buttons and give them a value; the name and value associated with
the submit will be passed as a request parameter:
private doSomething( request.getParameter( buttonName));

You are on the right track. Keep the sql with the model. The only thing is
don't let your collection of databeans make it to the jsp. That would
