Getting a localized string from the resource bundle

published by Yannick on 8 June, 2011 - 14:21

When you are working with multilingual applications, you will need to show all messages and labels in the language of the users. Therefore we use resource bundles.
When you define a resource budnle in the faces-config you can access it in any JSPX page but you also want to access it in a managed bean. This snippet shows you how:

Snippet:

public static String getMessageFromBundle(String bundle,String key) {
   FacesContext ctx = getFacesContext();
   try {
    ResourceBundle bundle =
     ResourceBundle.getBundle(bundle, ctx.getViewRoot().getLocale());
        return bundle.getString(key);
   } 
   catch (Exception e) {
      return "";
   }
}

While the bundle parameters must be the name of the bundle defined in the faces-config:

<resource-bundle>
  <base-name>
        yourBundle
   </base-name>
  <var>bundle</var>
</resource-bundle>
<message-bundle>
     yourBundle
</message-bundle>

Example:

If you want to add a message to the JSF Messages than you could use following example:

String invalidName = getMessageFromBundle("yourBundle",
                                       "invalid_name_message');
JSFMessageUtils.addFacesErrorMessage(errorMessage);

Applies to:

JSF

Managed beans
