I just uploaded the two presentations for my talks:

  • Java ME 8 Versus Java SE 8: What Developers Need to Know [CON6219]
  • Java ME 8: Java That Scales from the Desktop to Tiny Embedded [CON6222]

I am also working on making available the sample code/NetBeans project for the 2nd talk – watch this space.

FYI: The slides of most of the other JavaOne talks are also available for download, if you are looking for more.

Update:

Announcing Oracle Java ME Embedded 8.1 Developer Preview for Freescale FRDM-K64F

Java ME 8 is purpose-designed to bring Java-powered software intelligence to a wide range of embedded devices – scaling all the way down to resource-constrained micro-controllers. Since the release of Java ME 8 a few months ago we’ve seen tremendous interest in the industry in leveraging Java as the software platform to bring the next generation of functionality and flexibility to embedded systems and the Internet of Things.

Today, we are accelerating the adoption of Java ME 8 with a Developer Preview of Oracle Java ME Embedded 8.1 on ARM Cortex-M4 devices, in collaboration with Freescale and ARM.

What is it?

The Freescale FRDM-K64F is built around the Kinetis K64F with 120 MHz, 256 KB RAM/1 MB Flash, running ARM mbed OS and with an Arduino form-factor and pin-out. A popular prototyping platform for both the mbed and Arduino communities, now joining forces with the Java ecosystem.

The Oracle Java ME Embedded 8.1 Developer Preview on FRDM-K64F offers:

  • A feature-rich and optimized Java ME 8 runtime in 190 KB RAM, enabling highly functional Java Embedded applications on single-chip micro-controller systems
  • Out-of-the-box support for Java 8 language, core APIs, networking, device I/O, storage, and more
  • Simple installation with a complete and ready-to-run binary, just copy it onto the device
  • Rich development and tooling via Java ME SDK 8.1 and NetBeans 8 IDE
  • Complements existing Java ME 8 platforms such as Raspberry Pi, scaling Java ME 8 from large to small
  • Ideal for evaluation and prototyping of small embedded & IoT solutions

What next?

Presentation: For more information and background have a look at the short slide deck “Introduction to Oracle Java ME Embedded 8.1 Developer Preview”.

Download: The Java ME Embedded 8.1 Developer Preview and the corresponding Java ME SDK 8.1 Early Access #3 are available NOW on the Oracle Technology Network (OTN).

Documentation: The release comes with Release Notes and Getting Started Guide for FRDM-K64F. There is also a full set of Java ME 8 documentation.

So grab a FRDM-K64F board from your favorite electronics shop or distributor, download the Developer Preview, and get started! Head over to the Java ME Embedded OTN forum to ask questions.

And finally, if you are watching the JavaOne 2014 Java Technical Keynote keep your eyes peeled for those little FRDM boards running Java ME 8 … ;-)

Cheers,

Demo sample

Now that Java ME 8 is released a lot of people trying it out and are asking for sample code and demos. We’ve got you covered:

1) The first place you should go is the ”Java ME SDK 8 Developer Guide“. This is your one-stop-shop for getting started with Java ME 8 development on your PC (no external hardware required). Chapter 2 is “Creating a Java ME SDK 8 Sample Project”, and part IV is all about “Sample Applications”.

2) Next, you will want to browse the “Java ME Embedded Developer Guide”, which covers important topics for developing Java ME 8 embedded applications. Chapter 5 talks about “General Purpose I/O”, chapter 6 about “Working with the I2C Bus”, and chapter 7 about “The Serial Peripheral Interface (SPI) Bus”.

3) The Java ME SDK 8 comes with a whole set of ready-to-go demo applications. After installing the Java ME SDK 8 and NetBeans 8, start up NetBeans and make sure the “Java ME SDK Demos” plug-in is installed and active (this should be the default case). Then, create a new project and in the New Project dialog look under the “Samples > Java ME SDK 8.0” folder for a number of complete Java ME Embedded 8 demo projects.

4) Finally, check out the “Getting Started Guide (Raspberry Pi)” and the “Getting Started Guide (Qualcomm IoE)” for information on how to run apps on these platforms, including access to real-world peripherals via GPIO, I2C, SPI, UART, and others.

We are also working on additional demos and sample code – stay tuned for more information on this.

And remember to head over to the OTN Java ME Embedded forum to browse and ask questions – we are monitoring this forum on a regular basis.

Cheers,

— Terrence

Newsflash 757208

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. 

In the meantime, for be sure to check out my webcast “Introduction to Java ME 8” or the ”Java ME 8 Deep Dive” presentation.
