Configuring Navigation Rules
Navigation between different pages of a JavaServer Faces application, such as choosing
the next page to be displayed after a button or hyperlink component is clicked, is defined
by a set of rules. Navigation rules can be implicit, or they can be explicitly defined in the
application configuration resource file. For more information on implicit navigation rules,
see “
Implicit Navigation Rules
”
on page
164
.
Each navigation rule specifies how to navigate from one page to another page or set of
pages. The JavaServer Faces implementation chooses the proper navigation rule accord-
ing to which page is currently displayed.
After the proper navigation rule is selected, the choice of which page to access next from
the current page depends on two factors:
• The action method invoked when the component was clicked
• The logical outcome referenced by the component's tag or returned from the action
method
The outcome can be anything the developer chooses, but
Table 7-3
lists some outcomes
commonly used in web applications.
