Tell about the life cycle of Java Server Faces.

For simple applications, the life cycle phases are automatically managed by the Java Server Faces application framework. Not only it is managed automatically, but it also allows you to manage the lifecycle phases manually. The initial stage in the life cycle of a Java Server Faces application is when the client requests for a page through HTTP and ends when the server responds the request.
The life cycle phase of a JSF application is divided into phases:

• Execute phase
• Render phase
