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.xJSF 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



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.

02-ResourceLibrariesContractshttps://github.com/marfous/j1demo-pf



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



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



Powered w/ jQueryUI and ThemeRoller CSS FrameworkSkinning 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

Configuration of theme infrastructure

PrimePush, PrimeUI and PrimeMobile



PrimePush brings first class support with Atmosphere Framework– WebSockets, long polling, streaming, jsonp

PrimeUI is spin-off from the JSF suite, provides rich javascript widgets– autoComplete, dataTable and many others (~35 components)

PrimeMobile offers UI components for mobile devices, supports for:– powered by jQuery


PrimePush Checkin Demo w/ PrimeMobile in Action

PrimeUI integrated with REST Services

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.

Faces Flows


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/componenttagName = ...) // 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.

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.
