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?”.

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

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

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

Answer Two Eclipse was originally developed by IBM Eclipse has since been released into the
Open Source community And is continuing to evolve

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

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

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 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)

What Does Eclipse Do?
By itself, almost nothing Without the JDT and PDT, Eclipse is sort of like
Windows Explorer, only not as smart
©2004 Pluta Brothers Design, Inc. www.plutabrothers.com
What Does Eclipse Do?
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
©2004 Pluta Brothers Design, Inc. www.plutabrothers.com
What Does Eclipse Do?
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
©2004 Pluta Brothers Design, Inc. www.plutabrothers.com
What Does Eclipse Do?
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

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
©2004 Pluta Brothers Design, Inc. www.plutabrothers.com
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
©2004 Pluta Brothers Design, Inc. www.plutabrothers.com
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*
©2004 Pluta Brothers Design, Inc. www.plutabrothers.com
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!

Who Should Learn Eclipse/WDSC?
Who Should Learn Eclipse/WDSC? Java developers Web site designers Web application developers iSeries programmers iSeries tool vendors
©2004 Pluta Brothers Design, Inc. www.plutabrothers.com
Who Should Learn Eclipse/WDSC?
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
©2004 Pluta Brothers Design, Inc. www.plutabrothers.com
Who Should Learn Eclipse/WDSC?
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
©2004 Pluta Brothers Design, Inc. www.plutabrothers.com
Who Should Learn Eclipse/WDSC?
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
©2004 Pluta Brothers Design, Inc. www.plutabrothers.com
Who Should Learn Eclipse/WDSC?
Web site designers Plugins, including WYSIWYG editors, are
getting very powerful and plentiful The WebSphere tools are particularly good
©2004 Pluta Brothers Design, Inc. www.plutabrothers.com
Who Should Learn Eclipse/WDSC?
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
©2004 Pluta Brothers Design, Inc. www.plutabrothers.com
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
©2004 Pluta Brothers Design, Inc. www.plutabrothers.com
What’s the Bottom Line?
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
©2004 Pluta Brothers Design, Inc. www.plutabrothers.com
What’s the Bottom Line?
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
