About 18 months ago we embarked on an ambitious journey to deliver a major update of the Java ME platform standard by filing JSR 360 (CLDC 8) and JSR 361 (MEEP 8) in the JCP (“JSR 360 and JSR 361: A Big Leap for Java ME 8”).
Both JSR 360 and JSR 361 were unanimously approved this week, with 25 YES votes each. Java ME 8 is now a reality, bringing the power of Java 8 to small embedded. Stay tuned for more announcements soon.
In the meantime, for be sure to check out my webcast “Introduction to Java ME 8” or the ”Java ME 8 Deep Dive” presentation.

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.
