RE: Struts bean usage

[Alex Paransky]

Well, the documentation of the define tag states:

"
Retrieve the value of a specified bean property, and define it as an
attribute (in the scope specified by the toScope property) accessible to the
remainder of the current page
"

So, the bean "reportsForm" must already be present in the scope at the time
you are performing your define.  Who creates/populates the reportsForm bean
in the first place?  To make your code work, you may want to use jsp:useBean
to create a new bean in the scope that you desire, however, you will still
need to do something to populate it (a loadReports.do action that forwards
to the proper .jsp page perhaps).

I have a jsp page and am trying to add text created by a form bean.  I am
using  to define the bean and  to write the desired
information.

I am getting the error "Cannot find bean reportsForm in scope null"

Am I referencing my bean incorrectly?

I have appended the form bean that I am using.

Thanks
Courtney

RE: Struts bean usage

[Galbreath, Mark]

Because the bean is not "reportsForm," it's "ReportsForm."  Change the
"name=" parameter.

And why are you casting a ListArray() to a Collection in its constructor?
