Modular Mind

Tomorrow I head to Eclipse World and after doing so much training I’m really looking forward to sitting and listening to others for a change! I am going to be doing a few presentations at the conference, but in this post I wanted to focus on what I’ll be attending next week.

Converting Your Applications From Swing to SWT and the RCP

This topic is becoming increasingly important to my clients. I’ve seen more than a few projects that are trying to leverage existing AWT/Swing resources as they migrate to RCP and are struggling with how to do this properly.

Creating Graphical Editors and Views Using Eclipse GEF

I’ve used GEF occasionally over the past few years, but I’ve never had the opportunity to hear it described in a systematic way. I’m also excited to hear some more about Zest, which I’d love to start using in upcoming projects.

RAP or GWT: Which Java-Based AJAX Technology Is for You?

RIA technologies look to become central to future Eclipse architectures (see the e4 project for the details). I have to admit I’m still somewhat ambivalent about thin-clients and would rather see rich clients with awesome provisioning support instead.

Java UI Testing Patterns and Best Practices

UI testing is always problematic and I think approaching this topic from a patterns and best-practices angle makes a lot of sense. I’m particularly interested in ways to create UIs that are designed to be testable.

So that’s what I’ll be attending this year, and if you see me at the conference be sure to stop me and say hi. And if anyone is interested in having a beer or something, just let me know!

I try to keep marketing posts to a minimum on this blog (I think this is my first one…), but I’m excited to say I’m going to be offering my first public RCP Quickstart course in early November. I often get requests for RCP training from smaller groups of developers and up to this point I haven’t been able to meet this need. Finally, I’ve managed to find the time to schedule a public course that may work for these developers.

So if you’re interested in RCP training and the Washington DC area is convenient for you, I hope you’ll consider attending in November. To get started, you can check out the course syllabus and registration information.

On a slightly different note, I’ve just finished offering my first remote training course to a group of developers in Australia (hello to the gang in Melbourne!). The course went extremely well and it’s got me very interested in offering further remote courses. I’d be willing to offer public or private remote training classes for fairly small groups, so this may also be an option for smaller development teams, or for those in Australia :-)

We all like to attend conferences and most people like the idea of presenting at one. But when the excitement of your submission acceptance fades, many of us sit down to face an empty PowerPoint deck and wonder where to start. Creating an effective presentation is a difficult task and it’s made even more difficult by the fact that most of us have never been taught how to do it. 

I’ve spent some time this summer thinking about presentations and reading what I can on the subject. I’m hoping this makes me a better communicator, and in any case I now know what I’m doing wrong! For those of you currently working on presentations or thinking about submitting for next year’s EclipseCon, here are two books I highly recommend.

Presentation Zen

This book by Garr Reynolds is fundamentally about getting your head in the right place. Stylistically, the emphasis is on graphical simplicity and storytelling, but to me the best parts were those that got me focused on why I want to present in the first place. Read this book first to get inspired by what great presentations can accomplish. And also check out Garr’s blog which is full of good information.

One of the best suggestions Garr has is to watch great presenters at work. Spend a few hours watching TED presentations, and you’ll have a new appreciation for how good a presentation can be.

Nancy Duarte’s claim to fame is that she developed the slides used by Al Gore in his talks about global warming. In this book she goes into great detail about how to create an effective presentation. The emphasis here is on the nuts and bolts of creating (but not giving) a presentation, and believe me if you’re not a graphic designer this information will help a lot. By the way, this book is also available on O’Reilly’s Safari Books Online.

If you act on the information in these two books, you’ll be well on your way to becoming a great presenter and your audiences will thank you for it.

I’m in the early stages of incorporating this material into my work, but I can already see some benefits. And if anyone in the Chicagoland area would like to see where I’m at right now, I’ll be speaking tomorrow (September 16th) at CJUG on the topic of “OSGi: Why Java Modularity Matters”.

In a previous post I mentioned that I had not yet found a way to use Clover to perform coverage analysis when running PDE Build and the Eclipse Testing Framework. A very kind reader (thanks Nihal!) has posted a comment outlining how to get this combo running. I have to tell you, the solution is not for the feint of heart. But if you really need to use Clover, give it a try. As for me, I think I’ll stick with EMMA.

On a different note, I’m currently in the Houston airport catching a flight out before Hurricane Ike hits. To any Eclipse developers living in the Houston area (especially the students at this weeks RCP Quickstart class), stay safe and I wish you all the best.

In response to my last post on Eclipse RCP Trends, Chris Aniszczyk commented:

Deep down inside… I think it’s a marketing issue… we have done a poor job marketing RCP in my opinion. We have brand confusion that when people hear Eclipse still they think IDE, not a rich client platform. It’s my hope that with the new Runtime project, we have a chance to rebrand Eclipse into more of a platform under the Equinox umbrella.

I couldn’t agree more, and I’ve spent some time this summer trying to wrap my head around this issue. I should say up front that I have zero marketing experience. But on the other hand, I have spent a lot of time with RCP newcomers and have some experience viewing this technology through their eyes.

So what did I come up with? Well this might sound pretty obvious to some, but my conclusion is that RCP = modularity. Period. If you want to assemble (dynamically or otherwise) an application from a set of components/plug-ins/bundles/whatever, then RCP is the tool for you. Sure it’s a UI toolkit, sure it offers a workbench, preference pages, etc. But the core idea that animates RCP is modularity.

The good news is that Java modularity in general and OSGi/Equinox in particular are playing an increasingly important role in software development. We need to ride this trend and make clear that RCP is the visual expression of Java modularity. When you want to apply the principles of Java modularity in the UI space, RCP is the tool for you.

From a marketing point of view, this brings me to the same conclusion that Chris reached above. Basically, RCP needs to be rebranded as part of a suite of technologies related to Java modularity. In other words, RCP needs to become the Equinox UI.

Running unit tests with the Eclipse Testing Framework can be a real pain. I’ve tried to provide some help in previous posts. But one thing I haven’t addressed is how to properly set up a unit test environment.

The first question you might have is what is a test environment and why do I need one?. Well the short answer is that the Eclipse Testing Framework has a set of plug-ins it needs to run. The complete set of necessary plug-ins I refer to as a test environment. Yes, I just made this up, but it works for me.

In almost all cases, a test environment is composed of three things:

1. A complete copy of the Eclipse SDK.
2. The Eclipse Testing Framework.
3. Your code. This includes both your production plug-ins along with any plug-ins or fragments containing unit tests.

What is the job market like for Eclipse RCP developers? I’d say it’s pretty good. In my experience, people with RCP experience can demand their terms and sometimes even work remotely. There still isn’t a huge pool of developers with this expertise and demand seems to be increasing. If you’re looking for proof, check out this graph of historical Eclipse RCP job postings.

The overall numbers are still small compared to standard J2EE/web development, but things are definitely moving in the right direction. It looks like 2008 is going to be a good year for RCP developers!

Five years ago today a Bugzilla entry was submitted calling for the creation of the Eclipse Rich Client Platform. While I’m sure the idea was bouncing around before the entry was submitted, I think of this date as the point at which the idea of RCP began to become a reality.

And is it ever a reality! Over the last five years RCP has matured into an amazingly useful application development platform. RCP is now approaching its fifth major release, which will introduce the new p2 provisioning system. I can’t wait to see and be a part of what RCP will become in the future.

I’ve had the pleasure of working with RCP over most of these past 5 years, and have witnessed many success stories. I’ve seen RCP used in every type of organization you can imagine, and I’ve seen applications developed with RCP that I’m convinced would not have been possible without it.

So I’d like to take this moment to say Happy Birthday RCP!  And to all the developers who have made RCP what it is today – thank you! You’ve done an amazing job.

P.S. For any RCP developers who might be feeling thankful as well, why not show your gratitude by becoming a Friend of Eclipse?

I was all set to write a blog post today on creating an RCP target platform, and then it started to snow … and snow … and snow.

So I decided to take a snow day instead, which unfortunately means I spent most of the day shoveling. I did get a chance to take a walk with my dog, though.

Hopefully tomorrow I’ll be able to get back to work!

Note: For those following the saga of my post titles reverting to my WordPress user name, it appears the problem is that I have an avatar image in my WordPress profile (thanks Gunnar!). WordPress is embedding the image in my RSS feed with a “title” attribute and Planet Eclipse is grabbing the string from there. I’m now trying to work with WordPress to remove my avatar because there is no way to do this through their UI. The bottom line is if you use WordPress and you’d like to add your feed to Planet Eclipse, do not specify an avatar.

I gave a talk this morning at Eclipse World on Leveraging the Model-View-Presenter Pattern in Rich Client Applications. And as promised, here is the sample code illustrating the various approaches one can take in integrating MVP and RCP.

I’m about to catch a flight, so I don’t have time to go through all the details needed to get the code running. In short, though, if you get RAP via update site you should be able to run the code. I’ll try to help out with any issues you run into.

Thanks to all who attended the presentation!
