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

Update 3/20/2014: Added notes for b54 drop.

As announced 2 weeks ago, we have started semi-regular developer drops of Java ME 8.

Developer Drop b54 was just pushed out today. As before, this is provided “as is”, with no guarantees of stability or functionality. 

To access, go to the EA #2 downloads page and look for “latest developer build”:

Note: It is recommended to use the NetBeans 8 RC1 or NetBeans 8 GA “All” bundle together with the latest Java ME SDK 8 developer build.


Change of Device Access API in the b54:

  • The Device Access API name and namespace has been changed to Device I/O (DIO) in preparation for the Java ME 8 final release. This requires that you update the package imports in your application. The latest DIO documentation can be found here.

Notes on changes for the Qualcomm IoE platform in b54:

  • The previously separate Netsetup BrewMP application has been removed and the functionality has been integrated into the Java runtime. Network setup for WiFi/3G is now done as part of the Java runtime initialization.
  • A new BrewMP application called reboot_java has been added. It is optional and can be used to trigger a soft reboot (Java reboot without board reboot).
  • Network setup, AccessPoint API, and Cellular API functionality has been improved/made more complete.

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.


Please go ahead and give the latest developer builds a spin. And be sure to ask questions and provide feedback: Java ME Embedded OTN forum or

Update (9/25): Some users may be experiencing problems when installing the Java ME SDK 8 EA plugins into NetBeans. Please see the updated Java ME SDK 8 EA Release Notes for a workaround.

As I blogged recently, the Java ME 8 specifications are moving full steam ahead. And today, Oracle is announcing the immediate availability of Java ME 8 Early Access.

Java ME 8 in a Nutshell:

Java ME 8 is a significant update of the Java ME platform and provides a modern, flexible, and feature-rich embedded software platform that is aligned with Java SE 8 and allows more efficient development, deployment, and management of embedded software solutions:

Java ME 8 Early Access scales down to very small target devices – the single-chip solution used on the STM32F4DISCOVERY board has 192 KB of RAM and 1 MB Flash, and costs around US $5 in volume, yet can host a complete solution of Java ME 8 EA runtime, networking and device access functionality, and Java application.

With this update, Java ME 8 is positioned to be the platform of choice for intelligent devices and the Internet of Things.

To learn more about Java ME 8:

Getting started with Java ME 8 Early Access:

Java ME 8 Early Access is available now for the following developer boards:

  • Raspberry Pi Model B (ARM11/Linux)
  • ST Microelectronics STM32F4DISCOVERY (ARM Cortex-M4)

Software development is supported by the Java ME SDK 8 Early Access, which includes a Java ME 8 runtime emulation on Windows as well (so you can get started even without a developer board).

What’s New?

We’ve gotten excellent feedback on these releases and have found and fixed a couple of bugs and glitches and made usability enhancements. In keeping with the rapid evolution of the technology, we are today making available a set of refreshed bits:

  1. Oracle Java ME Embedded 3.3.1 EA for ARM Cortex-M3/M4
  2. Updated Oracle Java ME Embedded 3.3 EA for Raspberry Pi
  3. Updated Oracle Java ME SDK 3.3 EA and updated plugins for NetBeans and Eclipse

We have also expanded the documentation that comes with these releases as well as updated the embedded sample code that is available with the Java ME SDK 3.3 EA.

Developer should start using these updated releases right away to benefit from the improvements.

Important Notes For Installation:

  • You should update all versions together. The integration between the runtimes (1 and 2) and the tools (3) will work best if all are updated at the same time. So please uninstall previous versions of Java ME SDK 3.3 EA (via Windows “remove software”) and the NetBeans and Eclipse plugins (via plugin management) and then install the updated versions.
  • When installing the updated NetBeans plugins, you should use the manual installation method as described in the chapter 2-4 of the “Getting Started Guide for the Windows Platform”. The reason is that the NetBeans update center still contains the plugin versions of Java ME SDK 3.2 GA release (not 3.3 EA).

Getting Started:

Be sure to check out the improved and expanded “Getting Started Guides” and “Release Notes” for the platform you plan to use. Refer to the OTN Java Embedded Documentation Tab and expand on the section “Oracle Java ME Embedded 3.3 Release” (see screen shot).

3 3docs

It’s best to start with the Windows (via Java ME SDK) “Getting Started Guide for the Windows Platform”, which explains how to install the Java ME SDK and configure NetBeans and Eclipse.

To access the refreshed bits for the Oracle Java ME Embedded runtimes and the Java ME SDK, please go to the download page (be sure to refer to the section for the 3.3 releases).
