OK - so setting a request attribute stays with the request object.
But why do I lose the PARAMETER (request.getParameter()) stored in the
request?
I still have a reference to the same request object, don't I?

Richard,
You need to set the atrribute to the request in your action class. This
enables you to reference it from the JSP.
Example:
from Action to JSP:
perform(request) {
request.setAttribute("foo", fooInstance);
requestDispatcher.forward(request);
}
Regards,
Kevin

Subject: Model 2: Duration of Parameters / Attributes in Request Object
I'm currently using Model 2 architecture and pass the request object
from controller TO action TO jsp. If I have a parameter that was posted
through the controller servlet and I try to access that parameter (via
request.getParameter) in the jsp, I get null.
Why is this happening? I thought that if I maintained a reference to
that object I still have access to all the parameters and attributes?
Example(abbreviated code):
In HTML page:
submit via post value for textbox "foo";
>From ControllerServlet to Action:
doPost(request) {
action.perform(request);
}
from Action to JSP:
perform(request) {
requestDispatcher.forward(request);
}
in JSP
request.getParameter("foo");
Value is null.
Reading through the archives, I'm still a bit confused about the
duration of the request object.
