ResourceBundle

I need to read messages_hr.properties file that is in the classpath of web project.

1) Load properties file: 
ResourceBundle bridgeMsgBundle = ResourceBundle.getBundle("messages", new Locale("hr"));

2) Fomat text with parameters:
String text = MessageFormat.format(bridgeMsgBundle.getString("javax.faces.validator.LengthValidator.MAXIMUM"), 15);

In messages_hr.properties: 
javax.faces.validator.LengthValidator.MAXIMUM=* Maksimalan broj znakova je {0}.
