Registering Custom Localized Static Text
Any custom localized static text you create that is not loaded into the page using the loadBundle tag must be registered with the application using the resource-bundle element in the application configuration resource file for your pages to have access to the text. Likewise, any custom error messages that are referenced by the converterMessage, requiredMessage, or validatorMessage attributes of an input component tag must also be made available to the application by way of the loadBundle tag or the resource-bundle element of the application configuration file.
Here is the part of the file that registers some custom error messages for the Duke’s Bookstore application:
<application> ... <resource-bundle> <base-name> com.sun.bookstore6.resources.CustomMessages </base-name> <var>customMessages</var> </resource-bundle> ... </application>
Similarly to the loadBundle tag, the value of the base-name subelement specifies the fully-qualified class name of the ResourceBundle class, which in this case is located in the resources package of the application.
Also similarly to the var attribute of the loadBundle tag, the var subelement of the resource-bundle element is an alias to the ResourceBundle class. This alias is used by tags in the page to identify the resource bundle.
The locale-config element shown in the previous section also applies to the messages and static text identified by the resource-bundle element. As with resource bundles identified by the message-bundle element, make sure that the resource bundle identified by the resource-bundle element actually contains the messages for the locales that you specify with these locale-config elements.
To access the localized message, the page author uses a value expression to reference the key of the message from the resource bundle. See Performing Localization for more information.
