On the heels of recap #1 – here is recap #2 from the JavaOne 2015 Java ME keynote:
Java ME Embedded 8 endorsed by leading partners to enable intelligent edge devices:
For more details, see the video replay of the JavaOne Java ME keynote starting at 1hr:7min:50sec.
Here is the next Java ME 8 Developer Drop, b58. 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”:
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”:
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.
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.
Key features of the Java ME 8 and Java ME SDK 8 Early Access #2 releases:
- Improved support for the JSR 360 (CLDC 8 and GCF 8) draft
- Improved support for the JSR 361 (MEEP 8) draft
- Improved tooling support (Developer Agent, On-device Debugging, Memory Monitor, Network Monitor, CPU Profiler, Logging)
- Improved networking and connectivity, including wireless support (3GPP, CDMA, WiFi)
- Improved access to peripheral devices through Device Access API
- New APIs for RESTful programming (JSON, OAuth2, HTTP client)
- Updated Java ME SDK 8 EA #2, improving support for new ME 8 functionality, platforms, peripheral devices, tooling, and integration with NetBeans 8 Beta
- Ongoing support for APIs such as
- File Connection
- Wireless Messaging
- Web Services
- Security and Trust Services
- Bug fixes, usability, performance, and footprint improvements
- New support for Qualcomm IoE platform on Brew MP
- Improved support for Raspberry Pi Model B on Debian Linux
- Improved support for Windows 7

Back in July, Oracle announced the Oracle Java Platform Integrator (OJPI) program.
The OJPI program enables companies developing embedded products on devices to leverage the technologies Oracle is providing across their choice of hardware and operating systems. This allows companies 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 stacks for Java Embedded.
Since July, we have been busy expanding this offering with more information and additional releases, including:
- Oracle Java SE Embedded 7u40 for ARM and Power (in various configurations)
- Oracle Java ME Embedded 3.3 for ARM11 and ARM Cortex-M3/M4
- Oracle Java ME Embedded 3.4 for Qualcomm QSC6270T
For more background, please also see the related announcement “Oracle Delivers New Capabilities for Powering the Internet of Things” (including video).

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.
It almost got lost in the surge of announcements at JavaOne: Not only did we make available Java ME Embedded 8 Early Access, but we also released an update to the existing Java ME Embedded 3.x product.
Java ME Embedded 3.4 is based on version 3.3 but now also supports the Qualcomm IoE (“Internet of Everything”) developer platform:
- QSC6270T processor with 64 MB DDR RAM and 128 MB NAND Flash
- Tri-band UMTS/HSDPA + quad-band GSM, SIM slot
- 2.4 GHz WiFi a/b/g/n
- Supported I/O: SPI, I2C, GPIO, ADC, UART, SD card, on-board accelerometer, light + temp sensor
Alongside, we’ve also updated the Java ME SDK to version 3.4 to add comfortable application development and debugging on the Qualcomm IoE platform via a USB connection to the PC.
With this release, Java ME Embedded now supports a key part of the Qualcomm ecosystem, opening up new opportunities for embedded Java in a wide range of use cases.
A while back, Qualcomm announced development platforms for the “Internet of Everything” (IoE) based on Oracle Java ME Embedded.
Now these boards are on pre-order and the package includes a data plan (12 months at 50 MB / month).
An excellent way to get started with IoE development …
