At JavaOne a few weeks ago, Oracle made available the Java ME 8.1 Developer Preview release for the Freescale FRDM-K64F (“Java ME 8.1 in 190 KB RAM”) and announced the upcoming full release of Java ME Embedded 8.1 (press release).
On Monday this week, we followed up as promised and posted the General Availability (GA) releases of Oracle Java ME 8.1 and the Oracle ME SDK 8.1.
Oracle Java ME Embedded 8.1 and ME SDK 8.1 New Features and Enhancements
- Support for ARM Cortex-M3/-M4 micro-controllers
- Updated Raspberry Pi support
- Updated Developer Preview on FRDM-K64 with mbed
- Improved support for two additional Qualcomm Gobi device families
- New communication, security, and networking features
- New support for Eclipse IDE, including major update of the Eclipse MTJ plugin
- Developer improvements: Tooling over USB, heap analysis, faster communication
- A number of smaller enhancements and fixes
Java 8: Truly Scalable
With this release, Java ME 8 now fully lives up to its design promise of delivering a feature-rich Java 8 platform that scales from powerful embedded systems all the way down to resource-constrained singe-chip micro-controllers with as little as 128 KB of RAM.
Developers can now rely on a consistent, standards-based programming model and platform that allows true code reuse from large to small solutions … in most cases the same, unmodified application binary will run across the entire range of target devices – irrespective of the underlying hardware and software differences. This means faster time-to-market, improved security and flexibility, and the ability to deliver more product value, faster.
No other embedded software technology can do that today.

… and much more. Feel free to browse around, there is also a range of previous but still very relevant content as well.
In case you haven’t seen it yet:
Oracle released a new video about the challenges of building embedded solutions in the Internet of Things and how Java Embedded can help, including some interesting data and real-world use cases.

- 10/9/14: See also the JavaOne interview with Dimitar Valtchev, CTO of ProSyst
Last week at JavaOne, ProSyst announced a Scalable Device Management Solution System for Java ME devices, see here for the press release.
Using the ProSyst mPRM backend and cloud remote device management solution allows customers to remotely monitor and manage gateways and end devices, based on both Java SE and Java ME, from a single management domain using a range of device management operations and protocols.
mPRM has been shown to scale to more than 4,000,000 online devices in simulated operations on Oracle Exalogic Elastic Cloud systems, and is in commercial use at a number of large service providers.
Another good reason to consider Java Embedded for your next IoT solution.
I just uploaded the two presentations for my talks:
- Java ME 8 Versus Java SE 8: What Developers Need to Know [CON6219]
- Java ME 8: Java That Scales from the Desktop to Tiny Embedded [CON6222]
I am also working on making available the sample code/NetBeans project for the 2nd talk – watch this space.
FYI: The slides of most of the other JavaOne talks are also available for download, if you are looking for more.
Quick update on the Java ME Embedded 8.1 Developer Preview that was released on Sunday:
Some developers have reported problems with connecting the FRDM-K64F to the ME SDK Device Manager over USB as well as the inability to set static IP addresses on the FRDM-K64F. We have seen this as well and are working on fixing the issues.
In the meantime, the most reliable way to connect the FRDM-K64F to the ME SDK 8.1 EA #3 is to use DHCP addressing on the FRDM-K64F and then connect to the Device Manager via IP.
Also, please be sure to NOT run the ME SDK Device Manager and the manual proxy at the same time – they will conflict. To get started it is best to just use the ME SDK 8.1 (make sure to use version EA #3) and connect via the Device Manager to make sure tooling works that way.
