The first instance of the Massive Open Online Course (MOOC) “Develop Java Embedded Applications Using a Raspberry Pi” is currently underway.
The response has been overwhelming and we had to cut off registrations and put people on the wait list. So we are now announcing a repeat of the course starting May 19th, 2014 to give all of you who missed it the first time around another opportunity. Enroll now before space runs out again. It’s still FREE.
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”:
The current March/April issue of Java Magazine is chock-full with embedded content:
- From Smart Grids to Microbrews: Using Java ME 8 to manage utilities infrastructure AND to brew beer
- Java ME 8 and the Internet of Things: Top features of Java ME 8
- New to Java? How to become and Embedded Java Developer in Minutes
- JavaFX and Near Field Communication on the Raspberry Pi
… along with lots of other great Java content, especially related to this week’s launch of Java 8.
PS: For more info on the beer-brewing use case, see the screencast “Developing Modular, Service-enabled Applications: Java ME 8” (go here and scroll down to see the screencast under the “Java ME 8” section).
Java Magazine is free, but requires registration. Enjoy!
Java 8 is officially launching today!
Along with todays live launch event there will be lots of new information available such as a set of brand-new screencasts:
Java ME 8 is a key part of the Java 8 launch and will be available soon. Until then, there’s plenty to get started – for example, the Java ME 8 Early Access. Or check out the new Java ME 8 screencasts:
- Be an Embedded Developer in Minutes using Java ME 8
- JSR 360 – CLDC 8: Benefits of an Optimized Implementation
- JSR 360 – CLDC 8: Java Platform for IoT
- JSR 360 – CLDC 8: Generic Networking APIs
- Unified Development Experience for Java ME 8 and Java SE 8
- Accessing H/W Devices using Java ME 8 Device I/O API
- Java ME 8: Top 10 Features
- Java ME 8: Tackling the Challenges of Embedded Software Design
- JSR 361 – MEEP 8: A New Java Profile for the Embedded World
- Developing Modular, Service-Enabled Applications with Java ME 8
Lots to learn. Exciting times.
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.
The free Massive Open Online Course (MOOC) “Develop Java ME 8 Embedded Applications with Raspberry Pi” will kick off March 31 (original announcement here)
Space is filling up fast (we’re capping registration numbers to allow for good student/instructor ratio). This is going to be a very cool course, and the MOOC team just released a new video describing the outline and the goals.
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.
As in last years, Oracle will again have a big presence at Embedded World in Nuremberg, Germany.
Find us in hall 5, booth 271. At the booth, you can see several demos focusing on Oracle’s Internet of Things strategy and the benefits of Java for embedded software solutions, including showcase applications by partners such as Gemalto, Freescale, Eurotech, and Hitachi.
I will be doing some sessions as well (download the full conference program here):
- Thu, Feb 27, 9:30: A hands-on tutorial on “Desktop to Internet of Things in 12 Seconds with Java ME Embedded”
- Thu, Feb 27, 15:30: “Trust Me, I am an M2M Device”
So, pick up some Java while you’re at Embedded World, and not just the technology kind, but also the hot, coffee kind ;-)
See you at Embedded World!
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.
