Subject RE: findForward and Errors
Date Tue, 14 Aug 2001 21:01:48 GMT
Craig,
	Thanks for your reply.  I have tested the code in the logonAction
class it does work.  However, it only works when you use a "key" in the
properties file.  If I have this code in a "catch" statement, how can I use
the actual error message with the "getMessage()" method of the exception
class?   Any ideas on how to get around this?

Thanks

The Struts example application does something very similar to this in
LogonAction -- since that is where an invalid username/pasword combination
is detected.  I think this is a reasonable design approach.
