Thanks for that. It's difficult to know how much you know sometimes.
Meanwhile, I still have a problem with the input mapping. I took the logon page from
the struts example.
When the user puts in an invalid password they should return to the logon page.
However, when my action hits this code it fails:
return ( mapping.getInputForward() );
mapping.getInputForward() equals:
forwardActionConfig[path=/Logon,input=app.logonDefinition,name=logonForm,scope=session,type=com.mybdr.actions.LogonAction
I then get:
{...RequestProcessor] Unhandled Exception thrown: class
java.lang.NullPointerException
from
LogonAction.execute(Unknown Source)
Any ideas?
Regards,
Aaron

More of a standard/best practice than important or relevant to your
first question.
> Action using defintion as "input" as well as forward path.
Should work.

No, you need an action of some kind that will forward to a definition.
Most people use DefinitionDispatcherAction. See
http://jakarta.apache.org/struts/api/org/apache/struts/tiles/actions/Definit
ionDispatcherAction.html
Otherwise you end up with a basic link to a document with your tile name,
which if you stop and think about it makes sense. So you'll end up with a
404.

That'll work, too.
You also can't declare a global forward to a tile and expect to have
it work correctly, though, so don't try it. =)

Yeah, I noticed that, too. But I managed to figure it out--and it looks
like you're halfway there. =)
