How to Declare Message Bundle in JSF

There are two ways to declare Message Bundle in JSF:
1. Simply configured in faces-config.xml file.
<application>
  <resource-bundle>
    <base-name>wiki.com.messages</base-name>
    <var>message</var>
  </resource-bundle>
</application>

2. Use built-in JSF tag to declare Message Bundle. this should be for each and every jsf page. If same message is used for multiple pages then this should not be a good choice.
<f:loadBundle baseName = "wiki.com.messages" var="message"/>
