Using FacesMessage to Create a Message

Instead of registering messages in the application configuration resource file, you can access the ResourceBundle directly from the code. The validateEmail method from the Coffee Break example does this:

...
String message = "";
...
message = CoffeeBreakBean.loadErrorMessage(context,
    CoffeeBreakBean.CB_RESOURCE_BUNDLE_NAME,
         "EMailError");
context.addMessage(toValidate.getClientId(context),
    new FacesMessage(message));
...

These lines also call the loadErrorMessage to get the message from the ResourceBundle. Here is the loadErrorMessage method from CoffeeBreakBean:

public static String loadErrorMessage(FacesContext context,
     String basename, String key) {
    if ( bundle == null ) {
         try {
            bundle = ResourceBundle.getBundle(basename,
                 context.getViewRoot().getLocale());
        } catch (Exception e) {
            return null;
        }
    }
    return bundle.getString(key);
}
