HTML(5) Friendly Markup
Resource Library Contract

PrimeFaces


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

6


NetBeans IDE


Open source IDE
 Support for Java, PHP, C/C++, Groovy
 Latest features
– Java SE 7, Java EE 7 and JavaFX

Sample Codes


Sample codes to demonstrate the tips
 Mavenized projects from Java EE 7 archetype

 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

10


Form with usage of HTML friendly markup: validation by
Bean Validation API with localized messages, custom Bean
Validation annotation, passthrough attributes and elements,

Resource Libraries
Contracts

12


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

13


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

14


Expression Language 3.0

15



 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)

JSF scaffolding with
PrimeFaces

27


JSF scaffolding with PrimeFaces

– 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

28


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

Faces Flows

30


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)

31


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

32


Annotation based
component registration

33


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 = ...)

34


// implicitly: lowercased class name

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

35


File Upload

36


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

37
