I guess i should add explanation.
i want to save an object permanently on the value stack.
In my case this object holds many informations that configure my pages
(loginuserid.......). It is created inside my loginAction.
I can get it from an action with a get-Method, but this object is
permanent and doesnt matter for any action beside login/logout. But the
jsp uses it every time.
I could put this object into the session (which i currently do). But i
like the value stack, and prefere lines like "#Settings.loginUser.id"
instead of "#session.settings.loginuser.id"
Hope i could explain my "problem"

Hi,
reading your mail, it seems to me that you want te redevelop what
Struts 2 can already do. When you put a getter in your action, you can
access to your attribute in the jsp like you seems to want to. I can't
understand why you want to put another Interceptor. If it is to set
always the same value, you could use hierarchy to have a class that
deal with all of the common attributes and all of the others should
inherit from it and implements their owns attributes.
If it is a misunderstand from me, sorry...
regards
Sébastien

Hi,
currently i'm trying to use my own Class to store configuration data
for my application.
To access the options from within the jsp page i want to use the
struts 2 value stack. I somehow like the stack more than i like the
session.
My problem is the following:
i can put objects in the session, but how do i put one on the stack
so i can find it with something like:
value="#mySettings" ?
my current SettingsInterceptor looks like this (and doesnt work):
// get the action on which the interceptor is fired
Object action = actionInvocation.getAction();
// get the value stack
ValueStack stack =
actionInvocation.getInvocationContext().getValueStack();
// try to retrieve the bean
SettingsBean settings = (SettingsBean)
stack.findValue("mySettings");
if (settings == null) {
settings = new SettingsBean();
stack.set("mySettings", settings);
}
try {
((SettingsBeanAware) action).setPageSettingsBean(settings);
} catch (Exception e) {
}
return actionInvocation.invoke();

Alexander
