when using <s:text>, it always use the default resource file.

In Struts1, I have used the below code to set default locale in my filter

session.setAttribute("org.apache.struts.action.LOCALE",locale);

This worked for me : 

String language = userLocale.substring(0, 2);
String country = userLocale.substring(3, 5);
Locale locale = new Locale(language, country);
ActionContext.getContext().setLocale(locale);
session.put(I18nInterceptor.DEFAULT_SESSION_ATTRIBUTE, locale);

where the values of userLocale are of the form : fr_FR and the file for the resources is named resource_fr_FR.properties
