Popular Web 2.0 Technology

MashupsREST A lightweight web application that

combines data from more than one source into an integrated and new, useful experience

An architectural style that is best exemplified by HTTP

REST embodies the principles of a service-oriented architecture using the web as the SOA platform

Feeds A data format used to exchange

frequently updated web content

XML data streams in formats such as RSS and Atom

Ajax Asynchronous JavaScript and XML -

Ajax, is a group of inter-related web development techniques used for creating interactive web applications

Dynamic Scripting Dynamic languages are flexible and easy

to learn Adoption is growing as developers focus

more on Internet-centric 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

Which programming languages works with AJAX?

Scripting languages and Frameworks

• Millions of PHP developers• Popular web languages like Python and Ruby ar

e agile and dynamic languages• Developers like the popular frameworks like Rub

y on Rails, Grails, Django– “That’s what I expected exactly!”– Rapid development

• Easy to learn (according to learning Java or C#)



New Approaches in Java Technology

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

def number=0// list a file with line numbersnew File ('test.groovy').eachLine { line ->

number++println "$number: $line"

}

def number=0// list a file with line numbersnew File ('test.groovy').eachLine { line ->

number++println "$number: $line"

}

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



WebSphere sMash Core Values

速度

敏捷

简洁

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

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

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



Lower Skill Required than Java EE



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)



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



Optimized for REST

• Effortless creation of RESTful services and data feeds (RSS, Atom)

script as a resource– http://<host>:<port>/Employee.php



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

Access REST resource through AJAX

RDBMS

/app/resources/ employees.groovy

/app/models/ employees.json

ZRM.delegate()

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

serializationAccess resource data with Dojo

WebSphere sMash application



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



Security Offerings

• System-level authentication and authorization• OpenID consumer• Protection against Cross-Site Request Forgery

(CSRF) attacks• User service• Security token • Extensibility

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

}

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

}

You don’t have to understand how this piece of configuration works, just need to know how simple it enables basic authentication on

specific URI pattern

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 f

or sMash applications– Create, run, test, debug– Manage dependencies

• Provides visual/source editors– page– forms– scripts– iWidgets– activities



Social Capacity

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