Welcome to Java ME 8!

Last month, Java 8 was launched. Last week, the Java Micro Edition (ME) 8 specifications were approved

Today, we are announcing the general availability (GA) of the Java ME 8 release.

This release is the culmination of a two-year effort driving a major update of the Java ME technology as a modern embedded software platform, purpose-built as a foundation for new services in the Internet Of Things. We are closely collaborating with industry partners and are seeing strong interest and adoption in Java ME 8 across a number of markets such as wireless modules, automotive, smart sensors, healthcare, industrial automation, smart energy, logistics, and others.

Top 10 Features of Java ME 8

Java ME 8 has been designed to enable advanced embedded software intelligence and increased product value for a wide range of use cases and solutions while maintaining very low system requirements. Top 10 features include:

  1. Aligned with Java 8 for efficient development
  2. Designed for Embedded
  3. Highly portable and scalable
  4. Consistent across devices
  5. Advanced application platform
  6. Modularized software services
  7. Client domain partitioning
  8. Direct access to hardware devices
  9. Compatible with standard APIs
  10. Enhanced embedded tooling

For more information, please see the screencast “Java ME 8: Top 10 Features”.

What We Are Releasing Today

Todays release comprises of several of components:

Java ME 8 TCK (Technology Compatibility Kit) and RI (reference implementation):

  • Java ME Connected Limited Device Configuration (CLDC) 8 (JSR 360
  • Java ME Embedded Profile (MEEP) 8 (JSR 361)

Oracle Java ME Embedded 8 product implementations and tooling:

  • Oracle Java ME Embedded 8 product implementations for several embedded platforms (see below)
  • Oracle Java ME SDK (Software Development Kit) 8 for embedded software development 

Oracle Java Platform Integrator (OJPI) releases for Java ME Embedded 8:

  • Enables Oracle partners to deliver value-add products and services based on Java ME Embedded 8 (OJPI information)

Support for the following platforms:

We are also planning on bringing Oracle Java ME 8 to additional platforms such as micro-controller-based devices - please stay tuned.

Where to Find More Information

For more information, please see the following links:

Getting Started with Java ME 8

To get started developing with Java ME 8, download the Oracle Java ME SDK 8 which comes with a built-in Java ME 8 device emulation environment for rapid development plus great documentation to get you started.

Once you’re ready to move on to real hardware such as Raspberry Pi or the Qualcomm IoE platform, download the ready-to-run Oracle Java ME Embedded 8 platform binaries. 

Go here for the full set of Oracle Java ME 8 documentation, including:

  • Release Notes 
  • Getting Started Guides for all platforms
  • ME SDK Developer Guide
  • Java ME Embedded Developer Guide
  • API documentation

Finally, head over to the Java ME Embedded Forum to ask questions and get involved. And follow @javaembedded or @terrencebarr to stay in touch.

What Next?

Java ME 8 brings exciting new possibilities to the embedded software space. Get started today and stay tuned for more to come!

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.

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.

Jim Connors published a great blog post a little while ago, describing the benefits of using the new Java SE 8 language and API features on multicore embedded systems like the Boundary Devices BD-SL-i.MX6 (built around the Freescale i.MX6 quad-core architecture). 

As you can see in the above diagram, leveraging parallel Java SE 8 Lambda and stream operations can dramatically improve overall performance. What’s more, the effort on the part of the developer is minor and the resulting Java code is portable and scalable across all Java SE 8 platforms, including completely different underlying architectures such as ARM on Linux vs. x86 on Windows.

Compare that to a traditional embedded multicore application, which typically is built with specialized frameworks, knowledge, and tuning and results in platform-specific code with limited portability and scalability. Plus, potentially hard-to-find multithreading bugs …

Out-of-the-box multicore support is another great example of why Java Embedded makes a lot of sense for embedded solutions.

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 ;-( )
