How to implement multiple languages in a web site using struts?

[John Chang <jo...@yahoo.com>]

In struts, can I set the language that is to be used
in a querystring, and then the JSP can display in the
designed language?  How to write tag of
<bean:message... />?  How to set the corresponding
environment, including properties files, tld files,
web.xml?

Thanks a lot!

John

You can do this, but indirectly.

The Struts <bean:message> tag bases its language choice on a session
attribute that is stored under key "org.apache.struts.action.LOCALE".
(In a program, you would use the symbolic string constant
Action.LOCALE_KEY for this).  So, if you want to switch languages, all
you would need to do is

* Create a new Locale for the desired language
    Locale loc = new Locale("fr");    // French

* Store the new Locale under this session attribute key:
    HttpSession = request.getSession();
    session.setAttribute(Action.LOCALE_KEY, loc);
