Over the years, Oracle has been making big investments in Java for ARM-based devices.
This week, Oracle and ARM announced further expanding their collaboration on a number of fronts, from additional hardware platforms, porting layers, and optimized communication protocols, to 64-bit ARMv8 support, and IoT architectures.
Henrik Stahl, VP of Product Management in the Java Platform Group at Oracle, just posted an excellent summary: “ARM TechCon 2013: Oracle, ARM expand collaboration on servers, Internet of Things”. Highly recommended reading.

Update 7/23/13: A good article/interview is on eWeek: “Oracle Aims Java ME Embedded at the Internet of Things”
- Oracle Java ME Embedded 3.3 GA (General Availability)
- Oracle Java ME SDK 3.3 GA
- The Oracle Java Platform Integrator Program
Here are the details:
Oracle Java ME Embedded 3.3
Oracle Java ME Embedded is an optimized, feature-rich Java runtime for resource-constrained devices, covering a wide range of platforms from small micro-controller devices up to mid-range embedded systems, including “Internet of Things” (IoT) and “Machine-to-Machine (M2M) devices.
The 3.3 release comes with a range of new features and enhancements, such as additional peripheral support, developer productivity features (network monitor, memory status monitor), API enhancements, and other improvements. Ready-to-run binaries are available through Oracle Technology Network (OTN) for the following platforms:
- KEIL MCBSTM32F200 developer board* (ARM Cortex-M3/M4 with ARM RTX)
- Raspberry Pi Model B (ARM11 with Linux)
Further, the Java ME SDK features an integrated Java ME Embedded emulation environment, which enabled developers to develop and test Java ME applications directly on PCs without the need for a physical hardware platform.
Oracle Java ME SDK 3.3
Along with the update of Oracle Java ME Embedded, the Oracle Java ME SDK toolchain has been updated to support the new Java ME Embedded features and platforms as well as improved device emulation, integrated memory and network monitor, usability enhancements, full Windows 7 support, and more. The NetBeans and Eclipse plugins have been updated as well.
Oracle Java Platform Integrator Program
The Oracle Java Platform Integrator Program enables companies developing embedded products on devices to leverage the technologies Oracle is providing across their choice of hardware and operating systems, allowing them to increase their differentiation and value-add, improve application and service portability across a consistent platform, and reduce engineering efforts and time to market for their solutions through the pre-integrated and optimized Java Embedded stack.
Why is this important?
With this announcement, Oracle continues its push into the embedded space, with an enhanced and robust Java ME Embedded runtime, increased platform coverage, improved toolchain, and partner program that address a wide range of embedded use cases and opportunities in the IoT and M2M spaces.
Ok – Where can I find out more?
- See the press release and watch the new video “Oracle Grows Java Capabilities in the Internet of Things”
- Review the supporting resources (bottom of the press release page), including webcasts, “Getting Started” videos, and more
- Check out the updated product home page, with Data Sheets, FAQs, and White Papers
- Refer to a number of posts on my blog for more information (here, here, here, and here)
Exciting times. Stay tuned for more to come.
* Note: While the MCBSTM32F200 is the officially supported board, the release also works on the MCBSTM32F400 (which is the Cortex-M4 version)
JavaOne in Russia ended yesterday, with over 2000 developers attending.
Embedded Java was a a hot topic (as it is pretty much everywhere these days) – check out the video on the Smart Home demo with Java ME Embedded on Raspberry Pi, and catch up with other demos and things happening at JavaOne Russia.
Now that a lot of folks are kicking the tires with Java ME Embedded (see the last couple of blog posts), I just wanted to make sure you know where to go with questions:
- Lots of good resources are here and here (including “Getting Started Guides”, FAQ, videos, and API documentation)
- Check out the OTN Java ME Embedded forum and ask questions – our experts are monitoring these regularly
- Email us at: email@example.com - we’ll get back to you
Have you been working on a cool application, solved a tricky embedded problem, or helped deliver an industrial-grade solution using Java?
There is a lot of great stuff happening in the embedded Java space. The world wants to hear about it.
Submit your proposal to JavaOne 2013 in San Francisco and present your work to thousands of like-minded Java developers!
The Call for Papers has been extended by a week, to April 23rd (watch the web pages for updates).
Get extra credit from me for using Java ME Embedded on Raspberry Pi. Check it out and do something fun and inspiring with it.
At JavaOne 2012 Oracle announced its entry into the small embedded space: Java ME Embedded 3.2.
Today we are announcing the availability of two exciting follow-up releases:
- Java ME Embedded 3.3 for Raspberry Pi (Early Access)
- Java ME SDK 3.3 (Early Access)
With these releases, Java developers can now develop feature-rich embedded Java ME applications and run them on the popular Raspberry Pi board. The new version supports a number of new or improved features:
- Support of Raspberry Pi Model B running Linux Wheezy hard float
- Multi-tasking virtual machine for running multiple applications concurrently and reliably
- Full-featured application provisioning and management
- An enhanced Device Access API, which allows developers to access peripheral I/O directly from Java, including devices on GPIO, UART, I2C, and SPI
- Network and memory monitoring tools
- Various additional enhancements in both the Java ME Embedded runtime and the Java ME SDK
Get a quick intro by watching Simon Ritter’s webcast “Java ME Embedded on the Raspberry Pi”.
Go here to find out more and download Java ME Embedded and Java ME SDK, including an overview, Getting Started Guide, FAQ, and full documentation.
That’s all for today – I will post more information next week.
It’s the ultimate recursion: Making Java with Java
Last year, Vinicus Senger already proved you could make Java (the hot one) with Java (the equally hot one), with his “Having Fun with Home Automation and Java EE” project. See this parleys.com video.
Now, Sasha Wolter created the next iteration. As part of a project for the Deutsche Telekom Developer Garden he built a voice-controlled coffee machine, using the Raspberry Pi, Oracle Java, a Nespresso machine, and some network APIs of Deutsche Telekom.
