Wow,it works!
I now get it work when tried 2 times to find that "login_violation" the
actionName you defined in the global result is a style of wildcard you map
your action.
yup?
Thanks a lot!
Appreciation is given to Nuwan,too.He showed me a way to do my own
interceptors.

Oops, my mistake: interceptor returns "needLogin" (global result) and not
"needAuthentication" :-)
By the way, about the redirect result, it indeed "forgets" your action
error/message, as they are request scoped (it's equivalent to a HTTP
Redirect).

Perhaps your security interceptor could forward to an action, which has
the
responsibility to handle the error message:
The interceptor:
public String intercept(ActionInvocation actionInvocation) throws
Exception
{
Map session = actionInvocation.getInvocationContext().getSession();
User user = (User) session.get(Constants.USER_KEY);
boolean isAuthenticated = (null != user);
if (isAuthenticated) {
return actionInvocation.invoke();
} else {
return "needAuthentication";
}
The global results:
<result name="needLogin" type="redirect-action">
<param name="actionName">login_violation</param>
<param name="namespace">/</param>
</result>
And in your action (the login action, which gathers all login stuff):
@SkipValidation
public String violation() {
addActionMessage(getText("need.authentication"));
return SUCCESS; // to the login form
}
Worked for me.
Cheers,
Arnaud

I tried many times,but there's no solutions then.
Any help could be greatly appreciated.
