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

Any help could be greatly appreciated.
