May i know what are the difference among the scopes we set in the different places.

Say, my variable name called String name; is in the the form bean which, of course, has session scope.
differnt senariaos,what will happen
in my struts-config if i mention scope= request.
in my action class if i set the value of the name to session.
and in my jsp if i use some other scope.

may i know the actual process to be followed and priority is given to different files for the same scope variables.

This link contains an article that explains J2EE scopes pretty well. If you have the same variable name in different scopes and don't specify a scope in say, a bean:write tag, my understanding is that it will use the narrowest scope. For example, if you have the variable "foo" in both request and session scope, it will pick up the one in request scope first.
