Re: No form elements in the jsp- ActionForm

[Wendy Smoak]

From: "Sab" <[EMAIL PROTECTED]>
I will have a jsp page which will get some results from database as a
list.
But now at present, I have a button which is on this button.
I would like to know what will the ActionForm subclass will be?
I wrote jsp, Actionclass which takes the hidden name of event when
button is passed and in actionclass in execute I have the eventname to
go to another page(another.do) .
Without Struts, what needs to happen?  I think it's: the user goes to a 
page, clicks a button and then sees a page with database results.  (Are the 
results read-only or will the user be updating the database?)

It doesn't sound like you need a form for that first page with the button. 
Try it with a plain old  and see if that works.

I agree with Christian. I've found an XML validation website/tool which 
is invaluable when you're brain-dead & still required to write code:

Re: Create a jsp page with 1 button

Use a ForwardAction to simply forward to your button page.
There, you put a submit button inside a normal form tag.
Use JSTL to preserve possible session info:

" method="post">

Then your target has to be a custom action which gets the
data from the Model, puts it in some scope (request, usually)
and then forwards to your page 2.

RE: trouble referencing struts taglibs: TldLocationsCache?

[Martin Gainty]

Good Morning Msgr McGrath
If you install your  in a 
location other than YourWebApp\WEB_INF you would still have to update the 
web.xml web-app taglib-location
Or am I not understanding the thread ?

Hi All,
I'm migrating an application from WebLogic 6.1 to Tomcat 5.0, and having a
