This is a part of navigation in which one page is navigated to others. This section gives you something about the JSF Global navigation which makes the direct navigation between two or more pages. There is an example of Global Navigation in JSF has been implemented with the complete downloadable solutions like the example code and the illustration about the procedure of deployment of example. This type of the navigation navigate directly to the other sources which have to mentioned as it is.

Here, you will find the code of the example and can get more about the global navigation in the JSF application in very efficient manner. This type of navigation does not works like an anchor tag () of HTML (Hyper Text Markup Language). This type of navigation is shown by implementing the example in this section. There is the page that has to be referred in the example has been mentioned in the faces-config.xml file that is is handled by the action of the command button of the form from the page. You can see that the module of the code which is written in the faces-config.xml file that is like as follows:

	<navigation-rule>

<from-view-id>*from-view-id>
<navigation-case>
<from-outcome>secondpagefrom-outcome>
<to-view-id>/secondpage.jspto-view-id>
navigation-case>
navigation-rule>
