Internationalization in struts

I made one struts application.I want to support a Internationalization in my application for japanese.My Property file name is Application,Its working for Application_ja开发者_如何转开发.properties file but Its not working for Application_ja_JP.properties file.I am running a application on tomcat server. please help me.

I have created application to support two languages. I case you did not paste some code I will try to explain mine.

At first I create Struts action class to handle locales, there are methods of this class:

public ActionForward en(ActionMapping mapping, ActionForm form,
        HttpServletRequest request, HttpServletResponse response)
        throws Exception {      
    request.getSession().setAttribute(
            Globals.LOCALE_KEY, Locale.ENGLISH);
    return mapping.findForward(SUCCESS);
}

public ActionForward lt(ActionMapping mapping, ActionForm form,
        HttpServletRequest request, HttpServletResponse response)
        throws Exception {

    request.getSession().setAttribute(
            Globals.LOCALE_KEY, new Locale("lt"));

    return mapping.findForward(SUCCESS);
}

One method for English and one method for Lithuanian language.

I declared this action class in my struts-config.xml file:

<action input="/views/index.jsp" 
        parameter="method" 
        path="/locale" 
        scope="request" 
        type="lt.klc.action.LanguageSelectAction" 
        validate="false">
    <forward name="success" path="/views/index.jsp"/>
</action>

I declared my resources: (application.properties and application_lt.properties)

<message-resources parameter="lt/klc/resources/application_lt"/>    
<message-resources parameter="lt/klc/resources/application"/>

When I want to chage language I simple call this class by providing which method I want to call:

    <html:link action="locale.xhtml?method=en">English</html:link>
    <html:link action="locale.xhtml?method=lt">Lietuviškai</html:link>

Hope this helps.

Suppose you have two properties files-
struts_en_UK.properties
common.color = colour

struts_en_US.properties
common.color = color

The following code will fetch the resource from properties file as follows-
        Locale locale = new Locale("en", "UK");
        ResourceBundle bundle = ResourceBundle.getBundle("struts",locale);

        System.out.println(bundle.getString("common.color"));

        Locale usLocale = new Locale("en", "US");
        ResourceBundle usBundle = ResourceBundle.getBundle("struts",usLocale);
        System.out.println("Us Locale : "+usBundle.getString("common.color"));
