unknown="true" worked fine (and, as is expected, you can only define one
action
with the attribute unknown="true")
getUnknown sounds like its working as documented:
it returned "true" when invoked from the action class defined with
unknown="true",
and returned "false" for 'regular' action classes.
Thanks for the info!

Struts question: how do you handle an undefined
12/10/2004 03:24 ActionForward value?
PM
Please respond to
users
Steve, if you configure unknown="true" as part of your action mapping,
this action will be used if no action mapping is found and will forward to
the appropriate mapping.
I have not done this (or tried it), but I just checked the java doc for
ActionConfig and found that getUnknown indicates if this ActionConfig is
the default config in case none is found.
thanks for the question--helped me learn something.
Give that a try and report back :)
