Popular Web 2.0 Technology
Feeds
 A data format used to exchange Dynamic Scripting
frequently updated web content
 Dynamic languages are flexible and easy
 XML data streams in formats such as to learn
RSS and Atom  Adoption is growing as developers focus
more on Internet-centric applications
Mashups
 A lightweight web application that REST
combines data from more than one
source into an integrated and new,  An architectural style that is best
useful experience exemplified by HTTP
 REST embodies the principles of a
service-oriented architecture using the web
as the SOA platform
Ajax
 Asynchronous JavaScript and XML -
Ajax, is a group of inter-related web
development techniques used for creating
interactive web applications

Browser-side Programming Is
Hard
• Fighting for complexity
– HTML: structure data
– CSS: presentation
– JavaScript/Ajax: logic and interaction
– Server Integration
• Multiple browser
– Internet Explorer
– Firefox, Safari, Opera, etc

How? Read Books

works with AJAX?

Scripting languages and Frameworks

• Millions of PHP developers
• Popular web languages like Python and Ruby
are agile and dynamic languages
• Developers like the popular frameworks like
Ruby on Rails, Grails, Django
– “That’s what I expected exactly!”
– Rapid development
• Easy to learn (according to learning Java or C#)

Groovy
• Groovy is an agile and dynamic language
for the Java Virtual Machine
• Builds upon the strengths of Java but has
additional power features inspired by
languages like Python and Ruby
• Compiles straight to Java byte code so you
can use it anywhere you can use Java

What is Project Zero?
• A development community delivering the
best of agile Web 2.0
• Delivered WebSphere sMash
– PHP scripting, REST and Dojo in ONE
integrated runtime and tooling package

JavaScript toolkit

projectzero.org


projectzero.org

WebSphere sMash Core Values

• Convention over configuration
速度 • Application is server
• Rich User Interfaces Support

• Consistent application approach
• End to end web-based tooling
简洁 • Visual & programmatic editors

• Dynamic Scripting Support
敏捷 • Integrated runtime
• Pre-built services


projectzero.org

Lower Skill Required than Java EE


projectzero.org

a dynamic scripting platform
• Create Application Logic in one of two
scripting languages
– Groovy (for people that prefer Java)
– PHP (for the 3 Million existing PHP programmers)
• Java is positioned as the “system”
language
– implement system extensions and application libraries
– You can use Java (if desired)


projectzero.org

PHP Support
• PHP runtime built in Java
– To PHP.net as JRuby is to Ruby and Jython is
to Python
• Powerful blending of PHP and Java code
– Java and PHP code run in the same process
on the same Thread
• No need for Inter-process communication


projectzero.org

Optimized for REST
• Effortless creation of RESTful services
and data feeds (RSS, Atom)
script as a resource
– http://<host>:<port>/Employee.php


projectzero.org

RESTfully Expose Data
Enable Developers With A Simple Programmatic And HTTP Data API

WebSphere sMash application

Access REST resource
through AJAX /app/resources/
employees.groovy
ZRM.delegate( RDBMS
)
/app/models/
employees.json

Model application data
• Constrained set of APIs encourage a RESTful application
architecture
• Data model that maps well into Atom feeds and JSON
formats
• Robust framework for persistence, validation, and
Access resource data with Dojo serialization

projectzero.org

Platform Overview
• Application-centric runtime
– No “container”
– Instant on
– Clean (short-live process)
– Cheap (small footprint)
• A full stack runtime for Web
– Built-in everything you need
– Modular architecture
• You just need a JVM
– Java SE 5 or 6


projectzero.org

Security Offerings
• System-level authentication and authorization
• OpenID consumer
• Protection against Cross-Site Request Forgery
(CSRF) attacks
• User service You don’t have to understand how
• Security token this piece of configuration works,
just need to know how simple it
• Extensibility enables basic authentication on
specific URI pattern

@include "security/basicAuthentication.config" {
"conditions": "/request/path =~ /customers(/.*)?"
}


projectzero.org
Built-in Development Tooling –
App Builder
• Web-based IDE
– lets developers build application directly on the Web

• Built as a sMash application
• Provides full development lifecycle
for sMash applications
– Create, run, test, debug
– Manage dependencies
• Provides visual/source editors
– page
– forms
– scripts
– iWidgets
– activities


projectzero.org

Social Capacity
• Application life cycle management
– Command Line
– REST API
– Administration tool
