JSF for Nonbelievers: The JSF Application Lifecycle

Phase 5: Invoke application
At the fifth phase of the lifecycle -- invoke application -- the JSF controller invokes the application to handle Form submissions. The component values will have been converted, validated, and applied to the model objects, so you can now use them to execute the application's business logic.

At this phase, you also get to specify the next logical view for a given sequence or number of possible sequences. You do this by defining a specific outcome for a successful form submission and returning that outcome. For example: on successful outcome, move the user to the next page. For this navigation to work, you will have to create a mapping to the successful outcome as a navigation rule in the faces-config.xml file. Once the navigation occurs, you move to the final phase of the lifecycle.
