Oracle is running the “Internet of Things (IoT) Developer Challenge” until May 30th, 2014. Submit a video and the code of your cool project, and you may win a trip to JavaOne 2014, a laptop, or other great prizes!

Don’t know where to start? Oracle is also providing free live sessions and online training running through April to help you get going. For example, next Monday (April 7) at 6:00pm UTC the session is about the “Internet of Things, Java and Raspberry Pi”. Plus, there is more help via online forums and other resources.

Find out all about the IoT Developer Challenge at The Java Source blog.

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 java-me-embedded-feedback_ww_grp@oracle.com

OJPI stack

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 details, see the OJPI Landing Page. For a complete list of supported platforms, see the OJPI List of Deployment Platforms.

For more background, please also see the related announcement “Oracle Delivers New Capabilities for Powering the Internet of Things” (including video).

Qualcomm ioe

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
  • GPS
  • 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.

Java ME Embedded 3.4 and Java ME SDK 3.4 can be downloaded for free from OTN for development and evaluation purposes.

Best,

— Terrence
