Sample Backing Bean (Unlike Struts does not extend any Class)

 

package net.thedesai.mulejsf.backing;

 

import javax.faces.component.html.HtmlCommandButton;

import javax.faces.component.html.HtmlForm;

import javax.faces.component.html.HtmlInputText;

import javax.faces.component.html.HtmlOutputLabel;

import javax.faces.component.html.HtmlPanelGrid;

 

public class Login {

}



JSF tags

<f:loadBundle baseName=”net.thedesai.messages” var=”msgs”> will load net/thedesai/messageCC.properties file where CC is country code

<f:view locale=”de”>

<h:outputText value=”#{msgs.guessNext}”>

<h:outputText value=”#{msgs.guessNext}, #{foo.bar}”> will concatenate strings

<h:inputText rendered=”#{!bean.hide}>

<h:commandButton action=”#{user.checkPassword}”> will call checkPassword() method used by action, validator, actionListener and valueChangeListener attribute

 

Value Binding expression can be a.b a[“b”] or a[‘b’]  e.g a[b.propname] property computed dynamically

Can use expression with arithmetic, relational (<.>), logical, empty operator and ternary operators

 

Predefined objects

header, headerValues,

param, paramValues (request parameters)

cookie, initParam, requestScope (all request scope attributes), sessionScope, appliationScope, facesContext, view

Static Navigation

<h:commandButton action=”login”> will find page to show from faces-config.xml

Dynamic Navigation

<h:commandButton action=”#{user.checkPassword}”>

 

String checkPassword() { if (..) return “success”; else return “failure”; }
