Life cycle of a jsf web application starts when user makes a request.

Jsf life cycle. Apply request values phase. Start phase restore view 1. End phase restore view 1.

Introduction to jsf life cycle. Jsf can be abbreviated as java server faces is a type of java based server client communication that facilitates the request and response flow through the system. The jsf lifecycle is divided into two main phases.

The request processing life cycle starts as soon as a request is submitted to the jsf controller servlet and ends when the client receives a response for the request. A jsf application follows a certain life cycle for every request and response. Start phase apply request values 2.

Jsf lifecycle contains 6 phases as soon as a jsf application in initiated by calling the faces servlet which is configured in the web xml file series of activities will take place. The multiple phases that any request response has to go through in the jsf life cycle are restore view phase apply request value process validations phase update model values phase invoke application phase and render response phase in the same order of process flow. When the client submits a page the javaserver faces implementation performs several tasks such as validating the data input of components in the view and converting input data to types specified on the server side.

Following are the six different phases of jsf request processing life cycle and are given in the order they are executed by the jsf framework. On submission of a page various further tasks are performed like validation of data provided in components in the view data conversion according to types specified on server side etc. Add the following lines to the faces config xml to activate the lifecyclelistener.

An example of this scenario occurs when clicking a hyperlink on an html page opens a java server faces page. Life cycle of jsf specifies the phases of execution of jsf based applications. The phases are restore view apply request values.

Update model values phase. Jsf application life cycle consists of six phases which are as follows. During the life cycle the javaserver faces implementation must build the view while considering state saved from a previous submission of the page.

These different requests and responses result in three possible life cycle scenarios that can exist for a java server faces application. The restore view phase. The lifecycle of a javaserver faces application begins when the client makes an http request for a page and ends when the server responds with the page.

These activities come under the category of jsf request processing life cycle phases. So series of steps that an application follows is called life cycle. Request for the jsf page can be generated from the jsf page or a non jsf page and as similar the response can be given to jsf and or non jsf page.

This produces like the following in the system output. The six phases show the order in which jsf processes a form.
