Check out this nifty little handbook for budding mobile developers called “Don’t Panic – Mobile Developers Guide to the Galaxy“. It provides a high-level overview of mobile platforms and development and lists some of the common pitfalls and solutions. Great for developers who are just getting started in the mobile space. I’m told me the guide is also being made available soon as a wiki to encourage developers to enhance and grow it going forward.

On Thursday I head up to London for the Over the Air event. I’ll do two talks on Saturday on LWUIT and JavaFX Mobile. Check out the draft schedule. Plenty of interesting topics – I attended Over the Air last year and it was a fun, down-to-earth developer event. I’m looking forward to it. Maybe I’ll see you there?

JATAF_Header_small.jpg I’ll be speaking at OSiM in Amsterdam tomorrow (the 15th) on a panel about fragmentation in the mobile industry. I am planning to use that opportunity to introduce the JATAF project as an important new and collaborative initiative focused on driving down fragmentation and increasing consistency in the mobile Java space.

JATAF (Java Application Terminal Alignment Framework) was announced at JavaOne 2009 and is a joint effort founded by Orange, Sony Ericsson, Sun Microsystems, and Vodafone. The goal of JATAF is to deliver test cases that address fragmentation issues. Test cases which become approved by the JATAF technical board will be open source, distributed in a JATAF release, and built to run on the open source JDTF (Java Device Test Framework) test harness.

JDTF-screenshot.jpgJATAF is a open source community which is free and open to all and test cases are licensed under the Eclipse Public License 1.0.

Developers are encouraged to participate in JATAF in multiple ways:

  • Download and run test cases to verify fitness of devices they plan to develop content for
  • Join in technical discussions around fragmentation and testing
  • Provide use cases addressing fragmentation-related issues
  • Submit source code of tests

Use cases and test source code will be assessed and evaluated by the JATAF technical technical board for consideration to be included in future JATAF test packs. Operators, manufacturers and developers can then execute these tests to ensure device implementations function consistently and predictably across a wide range of deployment scenarios.

The philosophy behind JATAF is that the more OEMs, carriers, and developers collaborate and contribute to the test cases, the faster defragmentation of the underlying platforms can happen, thus lowering testing and porting costs for developers and increasing the quality and quantity of content for the Java ME ecosystem as a whole. Since the announcement in June over 190 test cases have already been added to the repository.

I’d like to encourage developers in the mobile Java space to have a look at JATAF. To learn more about the project please check out the JATAF home page, the JATAF project on, the JDTF project on, the JDTF screen cast, and listen to the Mobile & Embedded podcast #83 which features highlights of the JavaOne JATAF panel discussion.

CORP_LJEtoSunCust_2307_WSJ_v3c.jpgI can’t comment on the Oracle-Sun acquisition but I’d like to direct your attention to the first-page ad in todays Wall Street Journal.

I don’t think anyone should be doubting Oracles commitment. Personally, I’m looking forward to what’s to come.

Our documentation team has put together four brand-new screencasts on current subjects. They are 5 minutes each in length and a great way to get introduced quickly to the highlights of each topic. I encourage you to have a look:

LWUIT-screencast.png LWUIT (Lightweight User Interface Toolkit) screencast

A 5-minute overview to jump-start your understanding of LWUIT technology — everything you need to know about what it is, why it was created, who should use it, and the functionality it offers.

JDTF-screencast.png JDTF (Java Device Test Framework) screencast

This brief screen cast introduces JDTF, a flexible, configurable test framework that can be used to assess various aspects of the quality of Java Platform, Micro Edition (Java ME) device implementations.

JSR290-screencast.png JSR 290 (Java Language & XML User Interface Markup Integration) screencast

This brief screen cast describes Java Specification Request (JSR) 290, which enables the creation of mobile Java applications that combine Web UI markup with Java code.

JavaCard-screencast.png Java Card screencast

This brief screen cast walks you through the highlights of the Java Card Platform, the world’s largest standards-based computing platform.

javafx_logo_color_1.jpg Help drive the direction of JavaFX training and certification by taking the JavaFX developer survey.

You’ll need only 5 to 10 minutes. The JavaFX team is designing a comprehensive curriculum for Java developers. The primary objective of the curriculum is to enable developers to use JavaFX technologies to build rich internet applications. We’re looking for your input on the topics and tasks to include in the training.

Survey ends September 16.

WIPJAM has become a fixture on the conference circuit … if you’ve never been to one of these then this is your chance to experience it. What is WIPJAM@OSiM, you ask? Find out all about it here – and be sure to register! I’m looking forward to it and I hope to see you there!

Also, if you’re planning to attend OSiM World – I just got word I’ll be part of the panel on day 1 at 14:00 titled “Fragmentation is Ruining the Industry”. The sounds like it’s going the be a lively discussion …

And, yes, that’s me on the OSiM World front page – not my best camera shot ūüėČ

See you in 10 days in Amsterdam!

After nearly three years with the blogging system I am moving my blog to here on WordPress, starting today.

Along the way I am renaming it to “Across the Universe”: A wide-angle view of the IT industry, mobility and wireless, open source and open access, the business of technology evolution, and other related topics. I hope you continue to find it worthwhile as many of you have over the past years.

I won’t be moving the previous blog entries and comments. Please see my old blog (also linked in the blogroll on the left). However, during the transition I will be double-posting entries for a while to make sure nothing gets lost.

So, be sure to bookmark this page here and update your blog reader with the new RSS feed. New content will be coming rapidly.


— Terrence

PS: After I announced the move some people asked me if it meant I was moving away from, the Mobile & Embedded Community, or something like that. Definitely NO. I just moved my blog – I found I liked the features and functionality of WordPress better. The Mobile & Embedded Community is still where it’s at – see you there!
