What We’ll Cover...

Defining Eclipse Using Eclipse Examining Plugins Relating Eclipse to WebSphere Playing with Eclipse (and maybe a little

WDSC) Exploring the Pros and Cons of Eclipse Identifying Who Should Use Eclipse


Defining Eclipse


Two Different Answers: Eclipse is an extensible, platform

independent application development platform

Eclipse is a product originally written by IBM and subsequently released into the Open Source community

What is Eclipse?


Answer One Eclipse is an application development

platform Eclipse is platform-independent Eclipse is extensible

We’ll do this in reverse order…

What is Eclipse?


Eclipse is an application development platform

The function of Eclipse is to make it easy to develop applications. It’s primary role is as a replacement for Visual Age for Java, and it was largely written by the same people.

Because of this, you will see a definite bias towards Java development, but Eclipse was designed to be far more than that. I’ll get into that more in the section on “What Does Eclipse Do?”.

What is Eclipse?


Eclipse is platform-independent Java-based

Most of Eclipse is written in Java, and so will run on just about any platform.

But not 100% pure Java However, the Eclipse developers decided that

Swing, Java’s native user interface, was not suitable

So they created SWT, the Software Widget Toolkit, to replace Swing

What is Eclipse?


SWT – The Standard Widget Toolkit This is a big issue, and deserves mention right away SWT is NOT platform-independent Each platform needs a special native library Supported platforms include: Windows, Linux

(Motif/GTK), AIX, QNX, HP-UX, Solaris and Mac OSX

No third-party libraries are in development that I know of

More info later in the presentation

What is Eclipse?


What is Eclipse?


Eclipse is extensible Anyone can add to Eclipse First, it’s Open Source, so you can see how

everything works Second, the framework was designed

ahead of time to be extended, using something called plugins

Eclipse provides a workbench view (with wizards!) specifically devoted to creating plugins

What is Eclipse?


Answer Two Eclipse was originally developed by IBM Eclipse has since been released into the

Open Source community And is continuing to evolve

What is Eclipse?


Eclipse was originally developed by IBM OTI (Object Technology International) was

bought by IBM in 1996 They developed Visual Age for Java 3.5 This is the same team that then developed

Eclipse IBM spent roughly $40 million to develop the

original Eclipse IDE

What is Eclipse?


Eclipse has since been released into the Open Source community The source code is available Other people are encouraged to add to the

package There is a Project Management Committee,

which is made up basically of OTI folks: Greg Adams, Erich Gamma, Kevin Haaland,

Dave Thomson, John Wiegand

What is Eclipse?


And is continuing to evolve Each release adds functionality The difference between 2.0 and the 1.x

release was night and day Release 3.0 promises to add a tremendous

amount of new capability

What is Eclipse?


Using Eclipse


What Does Eclipse Do?

What Does Eclipse Do? By itself, almost nothing! Built to be extended by plugins As “shipped”, includes a JDT Also includes a PDT Over 300 other plug-ins in development

Some are free Some are commercial products

(Including WebSphere)



By itself, almost nothing Without the JDT and PDT, Eclipse is sort of like

Windows Explorer, only not as smart



Built to be extended by plug-ins While not a lot is included in the base

package, the framework is designed to be extended

A standard set of APIs are available to allow the creation of plugins

Just download a plug-in, copy it into the runtime library, and have it automatically included in the workbench

For the most part, this works! Maybe not as well in the next release, though



As “shipped”, includes a JDT The JDT, or Java Development Tooling, is a complete

Java IDE Written by the same folks who wrote Visual Age for

Java Most of the capabilities of VAJ are there

Generate setters and getters Evaluate and change variables

Plus some great new goodies Lots of refactoring support

For client-side Java development, it’s really all you need



Also includes a PDT PDT is the Plug-in Development Tooling,

designed to help in the creation of plugins Contains a complete set of wizards to walk

you through the process of creating a plug-in With the combination of the JDT and the PDT,

you have everything you need to extend Eclipse yourself


Examining Plugins


What Are Plugins?

Over 300 plugins: Application server (37) Code mngt (55) Database (21) Deployment (10) Documentation (15) Entertainment (25) Graphics (5) J2EE development platform (3) Languages (16) Network (4)


What Are Plugins?

Plugins (continued): Plugin Dev (3) Profiling (4) Team (23) Testing (26) Tools (21) UI (17) UML (5) Web (21) XML (19)


What Are Plugins?

Lomboz – the J2EE Plugin

Lomboz is a free eclipse plugin for the J2EE developers. It is a tool with a simple philosphy: "No magic tricks". Lomboz is integrated with many popular open source J2EE tools such as: Jasper, XDoclet, Axis and Ant. And naturally eclipse and the eclipse java development toolkit JDT.


What Are Plugins?

CodeBeamer – Collaboration Tool

CodeBeamer plug-in extends Eclipse 2 (WSAD) by providing team collaboration features such as Task, Bug and Issue management from within the Eclipse platform.


What Are Plugins?

Oxygen – XML Editor

<oXygen/> XML editor offers a large coverage of today's XML technologies supporting XML, XML Schema, Relax NG schema, DTD and XSL documents.


Relating Eclipse to WebSphere


Eclipse and WebSphere

The WebSphere Family WebSphere Application Server WebSphere Studio Other WebSphere Products

WebSphere Commerce WebSphere Payment Manager WebSphere Host Integration WebSphere Host On-Demand WebSphere Host Publisher WebSphere MQ WebSphere Personalization WebSphere Portal WebSphere Transcoding Publisher



WebSphere Application Server Currently at Version 5 WebSphere Express

Low cost entry level J2EE-compliant servlet container (no EJBs)

WebSphere Base Edition Includes EJB support

WebSphere Network Deployment (ND) Edition Designed for multiple server environments, with

failover capability



WebSphere Studio The following tools are based on Eclipse:

WebSphere Studio Site Developer (WSSD) WebSphere Studio Application Developer (WSAD) WebSphere Development Studio Client for iSeries

(WDSc) WebSphere Development Studio Client for iSeries

Advanced Edition (WDSc/AE) The WDSc products are used in conjunction with

a server piece that runs on the iSeries



WebSphere Studio Family WebSphere Studio Site Developer (WSSD) WebSphere Studio Application Developer

(WSAD) WebSphere Development Studio for iSeries

Replaces SEU and the compilers If you own any compiler, you upgrade to WDS WebSphere Development Studio Client for iSeries

(WDSCi) WebSphere Development Studio Client for iSeries

Advanced Edition (WDSCiAE)



WebSphere Studio Site Developer (WSSD) This is basically a very powerful design studio for non-

EJB web applications Additional editors

JSP editor CSS editor (I particularly like this tool) XML editor

Integrated test environment WebSphere 4/5 and Tomcat

Web Services development SQL support More features than I can list here



WebSphere Studio Application Developer (WSAD) Primarily adds EJB support EJBQL EJB/RDB mapping Includes EAR/WAR creation

There’s also WSAD integration edition Not a lot of information on that particular tool



WebSphere Development Studio for iSeries Replaces SEU and the compilers Used with one of two PC-based tools:

WebSphere Development Studio Client for iSeries (WDSc)

WSSD plus iSeries extensions Remote Systems Explorer jLpex editors for various iSeries languages

WebSphere Development Studio Client for iSeries Advanced Edition (WDSc/AE)

Includes all the WSAD capabilities as well

What Makes up WDSC?


What Makes up WDSC?

With WDSC, you can do everything required to build a complete multi-tiered application from the ground up.

Design the website Lay out the web pages Create a consistent look and feel Create images for logos Create JavaServer Pages and servlets Attach beans to the JSPs Create host programs to populate the beans Debug the entire application, both locally and on the host


What Makes up WDSC?

WDSC includes some legacy development tools for backwards compatibility, until their Eclipse-based counterparts are functional enough.

Visual Age for RPG CODE/400

WDSC also provides a number of productivity enhancements for quick development tasks.

Playing with Eclipse


Playing with Eclipse Editing a file Editing two files! Running a class Debugging a class A few quick glimpses at WDSc



Some Looks at WDSC


Examining the Pros and Cons of Eclipse


Pros and Cons of Eclipse

Pros FREE! Powerful base Java IDE, with features to rival Visual

Age for Java (and VAJ is dead, so…) OPEN SOURCE! Hundreds of third-party plugins available adding all

sorts of great capabilities FREE! Many commercial products are planning plugins Most importantly, WebSphere Development Studio

Client (WDSC) is based on it


Pros and Cons of Eclipse

Cons It’s not small

Disk – 80MB as installed Memory - 256MB is pretty much the absolute

minimum Requires a Java Virtual Machine (another 40MB)

It’s a little slow Startup is not particularly quick Scrolling through source occasionally causes

“hiccups” Takes some getting used to

Especially for non-VAJ users


Examining the Pros and Cons of WDSC


Pros and Cons of WDSC

Pros All of the positives of Eclipse Available to iSeries developers for FREE WSSD extensions

Web Site Designer, Page Designer Templates CSS and Image editors WebSphere Test Environment

iSeries extensions RPG/COBOL/CL editors Remote System explorer Projects*


Pros and Cons of WDSC

Cons It’s gigantic

Disk – about 1.5GB as installed, with each workspace taking 50MB and up

Memory – 1GB is required for real multi-language development

It’s a little slower Some wizards can take a while

Takes some getting used to But not if you already know Eclipse!


Looking at Who Should Use Eclipse


Who Should Learn Eclipse/WDSC?

Who Should Learn Eclipse/WDSC? Java developers Web site designers Web application developers iSeries programmers iSeries tool vendors



iSeries Programmers SEU is history You will need to know WDSC If you don’t have access to WDSC today, the

fastest way to upgrade your skill set is to learn Eclipse

By learning Eclipse, you also begin learning Java and web development skills



iSeries Tool Vendors Soon, the number one requirement for all tools

will be Eclipse integration More importantly, iSeries tools will have to be

integrated with WDSC In either case, you’ll need a plugin version of

your tool



Java Developers The JDT has all the great features of Visual

Age for Java, especially the superior debugging features

Most platforms are supported, and the Windows/Linux/Mac cross support is really superb

SWT is a technology you will at least have to address during design – even if you use Swing instead, you have to make an informed decision



Web site designers Plugins, including WYSIWYG editors, are

getting very powerful and plentiful The WebSphere tools are particularly good



Web Application Developers Whether you want to use commercial tools

(WebSphere) or free tools (Lomboz) there are tools available to allow you to create J2EE applications quite easily

XML and web services plugins are also available

The WebSphere Test Environment is an unbeatable environment for debugging web apps


What’s the Bottom Line?

Eclipse is not “Bill and Ted’s Excellent Open Source project” IBM spent $40 million to build Eclipse, then

gave it to the Open Source community Built by the OTI Group

If you’ve used Visual Age for Java, Eclipse will be very familiar

Eclipse is the foundation of all of the WebSphere Studio products You will eventually need to learn Eclipse or

one of its descendants



Eclipse by itself is just a framework It is extended by plugins

Eclipse comes with the JDT, which is a plugin for developing Java code You can edit side-by-side You can debug, even changing variables on

the fly There are hundreds of other plugins available



Everyone should learn Eclipse! iSeries programmers: if you don’t have access

to WDSC yet, start with Eclipse It’s free and available on the Internet If you do have access to WDSC, and the

resources to run it, do so NOW The more you know about WDSC, the better

your job chances are
