You shouldn't use a session key defined by the interceptor for internal usage to get an action locale.

If a request_locale parameter is detected by the i18n interceptor the requested locale is created and put to the action context and also to the session under the key specified by the interceptor.

If the next request to the interceptor doesn't include request_locale parameter then it gets a locale saved in the session, if not found the request locale is used.

Again the interceptor put returned locale to the action context. So, to get a locale used by the struts tags you should use

 Locale locale = ActionContext.getContext().getLocale();
