Announcing Java ME 8 Developer Drops
Recently, we released Early Access #2 versions of Java ME 8 and Java ME SDK 8. A lot of developers tried it out and feedback has been great. As expected (after all, this was an Early Access release) – there are still bugs and deficiencies and we have been busy fixing them … many are already taken care of.
In order to enable the developer community to follow along and benefit from the latest improvements and fixes we decided to provide semi-regular developer drops alongside the Early Access #2 release. These developer drops are planned roughly every 14 days, are based on the latest builds and have undergone basic testing. They are provided “as is”, with no guarantees of stability or functionality. This is bleeding edge
You can access these developer builds on the same pages as the other EA #2 downloads (look for “latest developer build”):
Note: It is recommended to use the NetBeans 8 RC1 “All” bundle together with the latest Java ME SDK 8 developer build.
Following on the heels of the release of Java ME 8 Early Access #2 the folks from Oracle Learning Library and the Oracle Java Evangelism Team just announced:
‘Massive Open Online Course’ (MOOC)
Develop Java Embedded Applications Using a Raspberry Pi
Starts: March 31, 2014
This course is based on Java ME 8 and gives a great introduction into getting started with embedded Java development on Raspberry Pi.

Announcing Java ME 8 Early Access #2
This blog has been quiet lately, but not for lack of activity … quite the opposite.
We’ve been extremely busy with Java ME 8 – getting the specs (JSR 360: CLDC 8 & JSR 361: MEEP 8) ready for final ballot and working hard on updating the first Java ME 8 Early Access at JavaOne 2013 (learn more) by adding the latest features as well as new platforms.
So today, we’re announcing new update releases:
- Oracle Java ME Embedded 8 Early Access #2
- Oracle Java ME SDK 8 Early Access #2
These releases are designed to continue to drive Java ME 8 momentum in the industry by giving the community access to the latest Java ME 8 functionality and to demonstrate Oracle’s commitment to delivering Java ME 8 as a modern and purpose-built embedded software platform that addresses the rising demands of the embedded software industry and the Internet of Things.

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?

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”.
