At JavaOne a few weeks ago, Oracle made available the Java ME 8.1 Developer Preview release for the Freescale FRDM-K64F (“Java ME 8.1 in 190 KB RAM”) and announced the upcoming full release of Java ME Embedded 8.1 (press release).
On Monday this week, we followed up as promised and posted the General Availability (GA) releases of Oracle Java ME 8.1 and the Oracle ME SDK 8.1.
Oracle Java ME Embedded 8.1 and ME SDK 8.1 New Features and Enhancements
- Support for ARM Cortex-M3/-M4 micro-controllers
- Updated Raspberry Pi support
- Updated Developer Preview on FRDM-K64 with mbed
- Improved support for two additional Qualcomm Gobi device families
- New communication, security, and networking features
- New support for Eclipse IDE, including major update of the Eclipse MTJ plugin
- Developer improvements: Tooling over USB, heap analysis, faster communication
- A number of smaller enhancements and fixes
Java 8: Truly Scalable
With this release, Java ME 8 now fully lives up to its design promise of delivering a feature-rich Java 8 platform that scales from powerful embedded systems all the way down to resource-constrained singe-chip micro-controllers with as little as 128 KB of RAM.
Developers can now rely on a consistent, standards-based programming model and platform that allows true code reuse from large to small solutions … in most cases the same, unmodified application binary will run across the entire range of target devices – irrespective of the underlying hardware and software differences. This means faster time-to-market, improved security and flexibility, and the ability to deliver more product value, faster.
No other embedded software technology can do that today.

In case you haven’t seen it yet:
Oracle released a new video about the challenges of building embedded solutions in the Internet of Things and how Java Embedded can help, including some interesting data and real-world use cases.
Java Embedded for IoT (2:51)
The Oracle Java ME documentation team has put together a short survey (7 questions) to help us understand better what type of Java ME documentation you are looking for and how we can improve it.
You’d do us a great favor (and, ultimately, yourself ;-) by quickly filling in the survey!
About 18 months ago we embarked on an ambitious journey to deliver a major update of the Java ME platform standard by filing JSR 360 (CLDC 8) and JSR 361 (MEEP 8) in the JCP (“JSR 360 and JSR 361: A Big Leap for Java ME 8”).
Both JSR 360 and JSR 361 were unanimously approved this week, with 25 YES votes each. Java ME 8 is now a reality, bringing the power of Java 8 to small embedded. Stay tuned for more announcements soon.

The first instance of the Massive Open Online Course (MOOC) “Develop Java Embedded Applications Using a Raspberry Pi” is currently underway.
The response has been overwhelming and we had to cut off registrations and put people on the wait list. So we are now announcing a repeat of the course starting May 19th, 2014 to give all of you who missed it the first time around another opportunity. Enroll now before space runs out again. It’s still FREE.
Here is the next Java ME 8 Developer Drop, b58. As before, this is provided “as is”, with no guarantees of stability or functionality.
To access, go to the EA #2 downloads page and look for “latest developer build”:
Oracle is running the “Internet of Things (IoT) Developer Challenge” until May 30th, 2014. Submit a video and the code of your cool project, and you may win a trip to JavaOne 2014, a laptop, or other great prizes!
Don’t know where to start? Oracle is also providing free live sessions and online training running through April to help you get going. For example, next Monday (April 7) at 6:00pm UTC the session is about the “Internet of Things, Java and Raspberry Pi”. Plus, there is more help via online forums and other resources.
Find out all about the IoT Developer Challenge at The Java Source blog.
I just posted an expanded and updated Java ME 8 Deep Dive slide deck on SlideShare.
(apologies for the partially messed up colors and slides, SlideShare is going that during the conversion process ;-( )
