What is 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

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
©2004 Pluta Brothers Design, Inc.

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
©2004 Pluta Brothers Design, Inc.
www.plutabrothers.com
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 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)
©2004 Pluta Brothers Design, Inc.
www.plutabrothers.com
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


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

Examining the Pros and
Cons of Eclipse
©2004 Pluta Brothers Design, Inc.
www.plutabrothers.com
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

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