Agenda
 Introduction
– Java EE 7 & JavaServer Faces 2.2, PrimeFaces, NetBeans IDE
 Tour through 10 features of the JSF and PF
– Feature overview
– Samples in action

 Java EE 7 – 14 JSRs and 9 MRs, themes:
– HTML5
– Developer productivity
– Enterprise demands
 JavaServer Faces 2.2 big ticket features:
– HTML(5) Friendly Markup
– Faces Flow
– Resource Library Contract
Java EE 7 & JavaServer Faces 2.2

 Open Source Component Library for JSF 2.x
JSF 2.2 is supported with PF version 4.x
 Very Lightweight w/ Zero Configuration
 Plenty of examples in Showcase, extensive
theming, provides mobile components
 Well documented, user guides, books & etc.
 Large and active community
PrimeFaces

 Open source IDE
 Support for Java, PHP, C/C++, Groovy
 Latest features
– Java SE 7, Java EE 7 and JavaFX
– HTML(5) client side development,
CSS preprocessors, JavaSciprt frameworks
– Cordova, FindBugs, VCS improvements
– PHP 5.4 and the newest PHP frameworks
NetBeans IDE

 Sample codes to demonstrate the tips
 Mavenized projects from Java EE 7 archetype
 Repository:
github.com/marfous/j1demo-pf
Sample Codes

HTML(5) Friendly Markup

 New namespaces
– passthrough elements: http://xmlns.jcp.org/jsf (TagDecorator)
– passthrough attributes: http://xmlns.jcp.org/jsf/passthrough (RenderKit)
 Advantages
– Getting control over rendered Facelets
– JSF components / JavaScript components / arbitrary mixing
– Write and style pure HTML with benefits of JSF

Form with usage of HTML friendly markup: validation by
Bean Validation API with localized messages, custom Bean
Validation annotation, passthrough attributes and elements,
usage of jQuery plugin at JSF component.

Resource Libraries
Contracts

Resource Libraries Contracts
 Theme definitions across one or more web applications
 Libraries consisting of templates, insertion points, resources
 Can be bundled directly into Web Application or within .jar library
 How to choose the used one:
– there is only one option
– static or dynamic view definition
– URL based definition within faces-config
 Multi-templating

Simple Resource Libraries Contracts usage, switching
RLCs dynamically using Expression Language and
ManagedBean.

Resource Libraries Contracts

Expression Language 3.0

 Communication between presentation layer and application logic
 Deferred or immediate evaluation of expressions
 Sets and gets data, invokes methods
 Features
– Standalone ELProcessor
– Concatenation, semicolon and assignments operators
– Static collections
– Collection Operations (aligned with Java SE 8)
– Lambda Expressions (aligned with Java SE 8)

Examples of Expression Language 3.0 features:
standalone EL Processor, operators, static fields,
collections, lambdas and collection operations.

-Prime Time with
PrimeFaces Components

-Prime Time with PrimeFaces Components
 With 100+ Rich Set of Components
 Built-in Ajax based on standard JSF 2.0 Ajax APIs
 Client APIs based on
 Enterprise theming w/ Theme Roller
With 4.0 – Sentinel We’re introducing cool stuff like,
– Client Side Validation
– Dialog Framework
– Tree Drag & Drop
– Deferred Loading and many more…

Examples on advanced UI components:
DataTable, Gmap, AutoComplete, Client Side
Validation, Tree Drag and Drop, The Dialog Framework
and others.

In the Jungle of
PrimeFaces Themes

In the Jungle of PrimeFaces Themes
 Powered w/ jQueryUI and ThemeRoller CSS Framework
Skinning and Structural CSS architecture
 ThemeRoller provides visual editor to create new themes
 ~40 themes available by only adding JAR dependency
 Advanced themes are also available
– Twitter Bootstrap Theme
– Metro UI Theme ($$)
 Configuration is done by <context-param> in web.xml

Theme variations on UI Components

JSF scaffolding with
PrimeFaces

JSF scaffolding with PrimeFaces
 Generation of CRUD skeleton from the database
– NetBeans IDE: JSPs or vanilla Facelets
– nbpfcrudgen plugin: Facelets with PrimeFaces
 Last feature – NetBeans 7.3.1 generates CDI artifacts
 Procedure
– Generate entity classes from database
– Generate JSF pages from entities

CRUD application generation using standard
JavaServer Faces templates, generation of
PrimeFaces templates.

Faces Flows

Faces Flows
 Reusable collection of screens with defined entry and exit points
 Nodes like switchNode, finalizer, methodCall etc.
 Derived from proven technologies: Spring WebFlow, ADF Task Flow
 JSF bound with CDI - @FlowScoped
 Definition:
– Faces-config configuration file
– Java definition using FlowBuilder (@FlowDefinition)

Sample wizard using navigation elements of the Faces
Flow, flow scope defined bean, Faces Flow component
as a plugable library.

Annotation based
component registration

Annotation based component registration
 Improved FacesComponent interface
 Eliminates needs for the TLD file
 CDI capable component
 @FacesComponent(createTag = true,
namespace = ... , // implicitly: http://xmlns.jcp.org/jsf/component
tagName = ...) // implicitly: lowercased class name

Usage of the tag defined by @FacesComponent without
any tag library, CDI binding in the component, Java SE
project as a custom tag library.

Annotation based component registration

File Upload

File Upload
 Servlet 3.0 multipart architecture
 Standard component with/without AJAX requests
 For lower JSF versions already available as PrimeFaces component
 Prerequisites
– Enctype multipart/form-data of the form
– Servlet 3.0

File Upload of the standard JSF 2.2 and PrimeFaces
library in action, with validation of type and size limit.
