Reactive Java EE

Want to know how to create efficient, high-throughput, and low-latency systems? In the reactive Java EE online session, you will learn how to use event-driven programming and asynchronous processing. Java EE Evangelist Reza Rahman will explore how Java EE as a whole responds to  the “reactive” requirements using features and APIs like JMS, MDB, EJB @Asynchronous, JAX-RS/Servlet/WebSocket async, CDI events, Java EE concurrency utilities and more. He will also show how to easily scale using Java SE 8 Lambdas and Completable Futures. Join him for this session at the next Virtual Technology Summit (VTS). 

We are celebrating 20 years of Java and innovations with Reactive Java EE, Java 8 Lambdas and IoT projects. The VTS is an interactive, online event, sponsored by the Oracle Technology Network (OTN). VTS is free, but you must register.  Join us for this exclusive event in APAC time zone, May 19 - 3:00 pm to 6:30 pm AU/SYD

Driverless Cars and Java

Paul Perrone is a regular fixture at JavaOne, and this year's conference is no exception. Perrone, founder and CEO of Perrone Robotics, will give a session called "Automated Vehicle Testing with Java." Perrone will talk about his company's Autonomous Vehicle Test System, developed for the Insurance Institute of Highway Safety (IIHS). The system, written entirely in Java, will be used to independently test the safety of crash-avoidance systems.

“Many of today’s vehicles already have ‘crash-imminent braking’ and other features,” says Perrone. “But up until now, the IIHS hasn’t really had a way to test how well these technologies work in real-world situations with cars traveling at highway speeds.”

User Groups at JavaOne

User group leaders from around the world meet once a year at JavaOne. Each year, they organize the Forum meeting the Sunday before JavaOne. Speakers and topics are vetted by community. Anyone attending JavaOne whether they belong to a user group or not are invited to those sessions. Make sure you arrive on time for the Forum on Sunday. It starts at 8:00am at Moscone West. Among the topics this year are NetBeans community and tools, Java EE and Glassfish update, lightning talks about productivity, Java tools for Maven and Java EE, free Java tools and how to teach Java. And you don't want to miss James Gosling. He will present his latest work on the Raspberry Pi, Robots and Small Devices. If you have not registered already.

Register by tomorrow Friday August 1, 2014 and take advantage of the Early Bird rate. It is a US $400 saving on registration!

Challenge Ends on Friday!

This is your last chance to win a JavaOne trip. Submit a project video and code for the IoT Developer Challenge by this Friday, May 30.  12 JavaOne trips will be awarded to 3 professional teams and one student team. Members of two student teams will win laptops and certification training vouchers.


Ask your last minute questions on the coaching form or the Challenge forum. They will be answered promptly. Your project video should explain how your project works. Any common video format such as mp4, avi, mov is fine.


Your project must use Java Embedded - whether it is Java SE Embedded or ME Embedded - with the hardware of your choice, including any devices, boards and IoT technology. The project will be judged based on the project implementation, innovation and business usefulness. More details on the IoT Developer Challenge website 


Just for fun! Here is a video of Vinicius Senger giving a tour of his home lab, and showing his boards and gadgets.

Source Code for IoT Developer Challenge Projects

Discover source code that can help you create a project for IoT Developer Challenge. These code samples are open source, available on Github and may be reused in your own project. 

Check out the Pi4J code to create a command from Twitter, to connect a camera, or sensors using I2C or any GPIO Raspberry Pi pins. Pi4J project is intended to provide a bridge between the native libraries and Java for full access to the Raspberry Pi.


You may want to create an interface for your project using JavaFX. There are simple steps to build a JavaFX interface.


Ask your questions on the forums and using the coaching form. Remember the deadline is in a week on May 30

IoT Developer Challenge Hangouts!

The last two Hangouts with our Coach Vinicius Senger are taking place tomorrow Thursday: 
  • A Hangout in Portuguese at 4:00pm California time or 8:00pm Brazilian Time 
  • Hangout in English at 6:00pm California time, 9:00pm Eastern time, 10:00pm in Brazil. The same session will happen on Friday at 9:00am in Singapore, 10:00am in Tokyo Japan, 8:00am in Jakarta Indonesia 
Vinicius will present his lab, tools, CNC machine and many devices that he created like robots, wifi camera, panels, home automation and more! Join us and learn about the many possibilities to use Java Embedded, different types of single-board computers and your creativity.

Ask your questions at the end of these Hangouts, on the Challenge forum or using our coaching form. We are making more code available to help with your projects. Check the code samples page on IoT Developer Challenge website.

IoT Developer Challenge Countdown

Things are heating up with less than 10 days left to submit a project video and the code for IoT Developer Challenge by the May 30 deadline. Don't miss this chance to win a trip to JavaOne for up to three members of your team!  Use the video to show how the project works.

There is still time to get your questions answered on the forums or by filling out the coaching form. We are monitoring both and your questions will be answered promptly.  

Project complexity is less important than completeness of concept. Mostly your project should work without requiring additional development. In the implementation, we look at whether you use Oracle Java Embedded - and you may use other languages or frameworks, of course. Real world implementation, a.k.a 'Utility of Entry', is only 25% of the judging criteria. Visit the the Challenge website for more details. 

The judges will score the Entries based on the following criteria:

Why Java ME?

Java ME is used on the Gemalto concept board, Keil Board, Qualcomm and Raspberry Pi boards. During this IoT Developer Challenge webinar, Globalcode Founder Vinicius Senger presents us with resources and advice to build a project with Java ME. You can start a project today with 2 other teammates and submit it to the IoT Developer Challenge. The three of you may win a trip to JavaOne 2014! 

Invited during the webinar was Java ME Product Manager Terrence Barr. He described the state of today's embedded market beyond phones and tablets, the advantages of Java ME over C or assembly development, products using Java ME, the new features of Java ME 8 and tips and tricks for developers. If you are looking to start with Java ME 8, check out his blog about getting started with samples and demo code.
