JSF Resource Bundle Example

In JSF, we can create a property file and dump all the projects specific messages that we want to display in the browser in one place. Either it’s a simple welcome message or an error message your Java class is returning to the browser. Place all the message in a name-value pair in a property file.

This eliminates hard coding same message on multiple pages. Also, we can change the message text in the property file instead of changing it in multiple pages. This also supports internationalization that I will cover in next post.

We need to follow these rules to create a JSF Resource Bundle.

  • Create a <FILE_NAME>.properties under your Java package. The file must end with .properties
  • Register the property file in faces-config.xml file


Resource Bundle in JSF Example


As you see below, I have created the property file constants.properties under Java package com.catgovind .  The second arrow point to faces-config.xml file where we need to register the property file

Register the property file with complete package name in the faces-config.xml file.  JSF appends the .properties automatically so don’t specify it here. The <var> parameter is a handle to access the properties. 



I have the following properties in the constant.properties file. The {0) and {1) are parameters here, we can pass values to this parameter at runtime 



Below is the Managed Bean class accessing a property from the Property file 



Below is the JSF page accessing the property file directly. Look at the handle message in the below JSF page should match with the handle message in faces-config.xml



Following is output in the Browser
