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:
- Aligned with Java 8 for efficient development
- Designed for Embedded
- Highly portable and scalable
- Consistent across devices
- Advanced application platform
- Modularized software services
- Client domain partitioning

A host of new content was released with the recent Java 8 launch and the YouTube Java channel features a number of interesting videos and interviews. For example:
“Building Block for the Internet of Things”, Nandini Ramani, VP of Java Product Development, Oracle
Get a new perspective on how enterprises may generate value from IoT and what it takes to make IoT work. Learn about key building blocks for IoT solutions. Get an overview of how Oracle’s products, including Java, enable end-to-end IoT deployments.
“Turning Devices into a Value-Generating Application Platform with Java”, Axel Hansmann, VP Strategy and Marketing Communication M2M, Gemalto
Learn about Gemalto’s vision for the future of IoT, strategy using Java, and adoption plans for Java ME 8. Find out more about Gemalto’s technologies and how they are used, from quick IoT/M2M prototyping to full-scale enterprise solutions.
I’ll be pointing out more interesting videos and content over the next couple of weeks.

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.
