Thx for your suggestions.
1) 2 action mappings -- 1 with validation turned off (welcome.do) and 1
with it on (login.do).
that means for every action, I've to create 1 more action. but it will
almost double the maintainence affort.
Uhm ... don't think so.  You could have a simple forward setup for the 
initial display of the form.  Then, have your actual "meat and potatoes" 
action.  That's two actions alright, but you only need to code one of them 
...

Realize, when many say "an action", they mean an entry in the XML file. 
Sounds to me like you're thinking two seperate classes.

2) Turn validation off, and handle that in the action:
then I've to give up struts validation framework........
Yep.  ... but you wouldn't have to have the extra action mapping.
I think these 2 suggestions are simple workaround for this problem, 
however,
it will break the framework in some degree....
Is there any other solutions come with Struts??
Nope.  Perhaps in time the Validation framework will evolve to be smart 
enough that it "knows" (or can) that it doesn't need to validate the form on 
the first display.  I'm actually kind of surprised this behavior hasn't been 
added in by now.  Seems it would be simple enough to do, but, perhaps I'm 
oversimplifying in my head.

Thanks!
Justy

There's a few different ways to handle this problem.
1) 2 action mappings -- 1 with validation turned off (welcome.do) and 1
with it on (login.do).
2) Turn validation off, and handle that in the action:
login.do
if (isSubmitted) {
errors = form.validate()
// redirect or do other authenticate work
} else {
return mapping.findForward("login");
}
HTH,
Dave
