©2004 Pluta Brothers Design, Inc. 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

©2004 Pluta Brothers Design, Inc. Defining Eclipse

©2004 Pluta Brothers Design, Inc. 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?

©2004 Pluta Brothers Design, Inc. 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?

©2004 Pluta Brothers Design, Inc. 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?

©2004 Pluta Brothers Design, Inc. 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?

©2004 Pluta Brothers Design, Inc. 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?

©2004 Pluta Brothers Design, Inc. What is Eclipse?

©2004 Pluta Brothers Design, Inc. 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?

©2004 Pluta Brothers Design, Inc. 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?

©2004 Pluta Brothers Design, Inc. 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?

©2004 Pluta Brothers Design, Inc. 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?

©2004 Pluta Brothers Design, Inc. 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?

©2004 Pluta Brothers Design, Inc. Using Eclipse

©2004 Pluta Brothers Design, Inc. 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. 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. 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. 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. 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

©2004 Pluta Brothers Design, Inc. Examining Plugins

©2004 Pluta Brothers Design, Inc. 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)

©2004 Pluta Brothers Design, Inc. What Are Plugins? Plugins (continued): Plugin Dev (3) Profiling (4) Team (23) Testing (26) Tools (21) UI (17) UML (5) Web (21) XML (19)

©2004 Pluta Brothers Design, Inc. 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.

©2004 Pluta Brothers Design, Inc. 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.

©2004 Pluta Brothers Design, Inc. What Are Plugins? Oxygen – XML Editor XML editor offers a large coverage of today's XML technologies supporting XML, XML Schema, Relax NG schema, DTD and XSL documents.

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

©2004 Pluta Brothers Design, Inc. 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. 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. Examining the Pros and Cons of WDSC

©2004 Pluta Brothers Design, Inc. 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. 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!

©2004 Pluta Brothers Design, Inc. Looking at Who Should Use Eclipse

©2004 Pluta Brothers Design, Inc. Who Should Learn Eclipse/WDSC? Java developers Web site designers Web application developers iSeries programmers iSeries tool vendors

©2004 Pluta Brothers Design, Inc. 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. 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. 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. 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. 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. 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. 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. 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

©2004 Pluta Brothers Design, Inc. Resources There are several books out there Including Eclipse: Step by Step, by yours truly, which is an excellent tutorial for Eclipse newcomers Order from MC PressMC Press WDSC: Step by Step comes out in September Pre-order from Amazon.comAmazon.com
