Thanks for you quick reply,Nuwan.

yeah,ur code works and action-error should be add to the original action(I
tested).
However,I set my global result in my default package,and when the invalid
action accessing was intercepted,the browser was redirect to the login page.
It's strange that the action-error did NOT display.I am sure that my
interceptor has been configured correctly and the actionError has been add
to the very action.
I guess the global result whose type is "redirect" cause this problem,but am
not sure.

So,I define my login result as dispatch,which is default, it works.My global
result is follwing:
--------------------------------------------------------------------------------
<global-results>
            <result name="error">/error.jsp</result>
            <result name="login">/common/login.jsp</result>
            <result name="invalid.token">/error.jsp</result>
        </global-results>
----------------------------------------------------------------------------------

Does it work?yes.action error has been add and can display correctly.
The problem is that I can NOT use redirect type any more.As a result,the
doLogin action---the login form's action---can not mapped,as  the namespace
now is still the invalid action's.
eg.I access :http://localhost:8080/myapp/kms/showNews.tbs before logged in
Then access was intercepted and dispatched to :
http://localhost:8080/myapp/common/login.jsp
so I logged.
The form was submitted  to http://localhost:8080/myapp/kms/doLogin.tbs
which should be:http://localhost:8080/myapp/common/doLogin.tbs

Any comment?

Thanks a lot.
