Answer 1

Lets say you have following two messages files

    messages.properties
    messages_de.properties

Setting the Application Locale
There are three ways of setting the Application Locale and I think you need the first one here.

1-You can let the browser choose the locale.

Set the default and supported locales in WEB-INF/faces-config.xml:

   
      
         en
         de
      
  

When a browser connects to your application, it usually includes an Accept-Language value in the HTTP header

2-You can set the locale programatically.

Call the setLocale method of the UIViewRoot object:

UIViewRoot viewRoot = FacesContext.getCurrentInstance().getViewRoot();
viewRoot.setLocale(new Locale("de"));

3-You can set the locale for an individual page
By using the f:view element with a locale attribute—for example:

The locale can be dynamically set:

Declaring message bundles
Now that the Locale is set you can use one of the following two ways to declare message bundles

1-Via faces-config The simplest way is to supply a file named faces-config.xml in the WEB-INF directory of your application, with the following contents:

   
      
         com.corejsf.messages
         msgs
      
   

2-At each JSF page that needs access it. Instead of using a global resource bundle declaration, you can add the f:loadBundle element to each JSF page that needs access to the bundle, like this:

In either case, the messages in the bundle are accessible through a map variable with the name msgs.

Showing appropriate label on button Now lets say default properties file i.e english has property

next=Next

and German has equivallent i.e

next=Weiter

And you have set the locale and declared mesg bundle you can access it to put the label on a command button like
