Internationalization

A JSF application can be internationalized with standard resource bundles (java.util.ResourceBundle) and messages. Resource bundles are suitable to internationalize the text on the components, controls, and digital assets; whereas message files are meant to internationalize the JSF validation errors.

In a Gradle or Maven project, we will add a resource bundle or message file to the src/main/resources project location with the necessary Java package as folders.

Resource bundles

We will configure the resource bundles in the Faces configuration file, /WEB-INF/faces-config.xml, for the web application.

For the contact details application in Chapter 4, JSF Validation and AJAX, we have two resource bundle files in English and German: appMessages.properties and appMessage_de.properties respectively.

Here is the English language bundle:

// uk/co/xenonique/digital/appMessages.properties
contactForm.firstName=First Name
contactForm.lastName=Last Name
contactForm.houseOrFlatNumber=House...
