Deliverables Mandatory

Your project in a public repository, fully documented Optional

An article that will be published on IBM DeveloperWorks detailing your experience

Eclipse projects: A feed into planeteclipse.org detailing your experience


Projects Learning Skills

Software Engineering Skills Team Project Planning and execution

Collaboration, Networking

Rapid Decision Making

Open source community involvement (process, resources..)

Research and resources evaluation

Concepts Emphasized Open Source Process

Design Patterns

eXtreme Programming


Why Open-source?

Standardization of the rail network enabled industrialized America and Europe

A connecting platform fueling growth, creating new business opportunities Connecting resources with factory efficiencies Connecting goods with markets Enabling new distribution models (Sears Roebuck)

Other technology platforms: electricity grid, national highway systems, ……..the internet

“Standards contribute more to economic growth than patents and licenses.”

"Economic benefits of standardization“, Technical University Dresden (TUD) and the Fraunhofer Institute for Systems and Innovations


Web 2.0 MASHUPPROJECT


Mashup

A hybrid application that combines content from more than one source.

Very popular Web 2.0 idea

Mash-up (you can use a hyphen if you want)

Mashups are the next logical step in Service Oriented Architecture

The real power in Web services comes from combining

Web services are typically specialized, mashups are “situational”

Development without central authority


Web 2.0

Web 2.0: O’Reilly Media coined the term

Web 1.0 vs. 2.0

One-to-many vs. many-to-many publishing

Application gets better as publishers make it better vs. application gets better the more people use it

No AJAX vs. AJAX


What is a Web service?

W3C Web Services Architecture Group

“A Web service is a software system designed to support interoperable machine-to-machine interaction over a network. It has an interface described in a machine-processable format (specifically WSDL). Other systems interact with the Web service in a manner prescribed by its description using SOAP messages, typically conveyed using HTTP with an XML serialization in conjunction with other Web-related standards.”


Service Oriented Architecture Roles

Service Requester

Service Registry

Service Provider

FindDiscover service

PublishAdvertise service

Bind/InvokeRequest service


SOAP

A W3C Specification

An XML format, typically holds information for a Web service method call, or a response

Programming language independent

SOAP expanded: Services-Oriented Access Protocol

Used to be Simple Object Access Protocol


WSDL

Web Services Description Language

A kind of IDL (Interface Definition Language)

An XML format to describe a Web service’s capabilities

Describes a service as a set of endpoints operating on messages


XML/Java XML Parsers

Parsers help with validation, well-formedness checking, building a DOM, notifying the application of errors

Two API Standards: DOM and SAX

Xerces2

Data Binding APIs


Suggested ApproachEnvironment setup

Service discovery

Real Mashup Exampleshttp://www.allapis.com/

Yahoo_Flickr_Weather_Maps.aspx

Allows users to search US cities/locations - provides users with information on the city requested

Weather Forecasts

Wikipedia geo Articles

Flickr photos

APIs used Flickr

GeoNames

Yahoo Geocoding

Yahoo Maps


Skills RequiredJava Programming, nothing fancy

Basic web service concepts: SOAP, WSDL

Basic web-application concepts: URLs, HTTP, JavaScript, server-side scripting (JSP, PHP, other)

Basic XML (syntax, parsing)

AJAX (would be nice)

CSS (optional)


Gain ExperienceJ2EE

SOAP

Axis

JAX-RPC

XML

Web UI

AJAX


RUBY ON RAILSPROJECT


What is Ruby On Rails

Ruby on Rails is an open-source web framework that's optimized for

programmer happiness and sustainable productivity. It lets you write beautiful

code by favoring convention over configuration.

- http://www.rubyonrails.org


Why Ruby on Rails?

RoR allows you to quickly build webapps.

RoR gets a lot of buzz.

RoR is fun.


Required Skills

Ruby Or another dynamic language like Python

HTML

JavaScript

CSS

DBs – MySQL is the easiest


Ruby On Rails Projects

Choose your own adventure!


ECLIPSE PROJECT


What Is Eclipse?

“Eclipse is an open source community focused on developing a universal platform of frameworks and exemplary tools that make it easy and cost-effective to build and deploy software in today’s connected and unconnected world.

Eclipse is a consortium of major software vendors, solution providers, corporations, educational and research institutions and individuals working together to create an eco-system that enhances, promotes and cultivates the Eclipse open platform with complementary products, services and capabilities.

Eclipse Strategic Goals

To define an open development platform

To foster a vibrant open source community well regarded for innovation and quality

To enable an ecosystem

To be ubiquitous


Why IBM? Why Eclipse?

We like Eclipse, we founded it and then donated it to the open-source community.

IBM and even competitor’s products are being built on Eclipse technology.

There is a large future invested in Eclipse.


Eclipse Project GoalsProvide open platform for application development toolsRun on a wide range of operating systems

Support both GUI and non-GUI applications

Remain language neutralPermit unrestricted content types

HTML, Java, C, JSP, EJB, XML, GIF, …

Facilitate seamless tool integrationAt UI and deeper

Add new tools to existing installed products

HTML XMLEJBJSPC


Eclipse Community

Celebrities! Erich Gamma (GoF, IBM Distinguished Engineer, JDT Lead)

Ward Cunningham (Wiki founder, Eclipse Foundation)

Strong Community http://www.eclipse.org/community/index.html

Newsgroups

Plug-in Architecture Plug-in

smallest unit of eclipse functionality

details specified in it's plug-in manifest (plugin.xml)

plugins can add code, define extension points, and contribute to extension points

Extension point named entity for collecting contributions

Defines API contract

example: extension point to add menu actions Extension

an instance of an exention point contribution

example: a specific menu action Controlled extensibility

SampleEclipse Plug-In Ideas

Eclipse SWT embedded Firefox browser widget (highly requested by the community)

Eclipse Mono Development Environment Visualization of Eclipse's Plug-ins so it's easier to see

dependencies and other things Distributed Debugging Shared Editing VOIP in Eclipse using ECF (http://www.eclipse.org/ecf ) and

Google's Jingle API Mylar support for C/C++ editing with CDTMany, many more
