Check out IoT at JavaOne!

"We are always creating new IoT applications and encouraging others to improve them. Lhings is the networking tool that let us make it very easy. This time we wanted to make something we use in our everyday lives which is traditionally non-technical, as is a table, to be connected to the Internet and then provide new services that could be useful in some applications" explains José Pereda, who is part of the Lhings team. Based in Spain, the team won aJavaOne trip during IoT Developer Challenge.  

"We wanted to show that IoT is useful in real scenarios and it's accessible to anyone. Likewise, we would like to encourage developers to reproduce and improve it!" further explains José. You will get a chance to meet them at JavaOne.  

In the Internet of Things session track at JavaOne, you will learn about Java Embedded and discover great applications. Register today with the Flash Sale code DFS4, you will save US $400   

José is also presenting four talks at JavaOne

  • JavaFX 3D: Advanced Application Development
  • How to Build the Game 2048 with JavaFX and Java 8: Lessons Learned
  • Debugging and Profiling Robots with James Gosling
  • Create the Game 2048 with Java 8 and JavaFX

The Java Hub at JavaOne!

Nighthacking moves in! Join Stephen Chin as he interviews Java developers attending JavaOne. You will learn from fellow developers about ingenious ways to get your job done with the tools and technologies they use. Those interviews will be live at Java Hub during the whole conference and live streamed online.

The Hackergarten is where developers contribute to JSRs and open source projects. Whether you are a veteran contributor or a beginner, you are invited to participate for as long as you want. You can stay for less than an hour, several hours, a day, or the entire time of the conference. JSR contributors will be onsite to help. Topics include Java EE, Data Grids, Java SE 8 (Lambdas and Date & Time API) and OpenJDK. Java Champion Andres Almiray organizes Hackergarten at many conferences around the world. Check the hackergarten.net for events close to you!

What's that Java and the Internet of Things? Check out what's new with the platform and how it provides a great solution for the Internet of Things. Whether you are working in the industry or just want to do your own DIY projects. Stop by Java IoT Demo Showcase and learn what you can do with Java. The cool keynote demo will be there as well for all 3 days of the conference.

Learn how to use 3D Modeling with JavaFX 3D, Java Embedded, and 3D printing. You will experience the entire process from the modeling interface to the 3D printing of no less than the Duke. Computer scientist Michael Hoffer from the Goethe-Center in Germany will demo his 3D modeling and printing.

The scavenger hunt at the Java Hub will add a twist of fun to the discovery of Java technologies. The Java Hub will be located in the JavaOne Exhibit Hall at Hilton San Francisco Union Square.

Register today with the Early Bird rate to save $400 off the onsite price!

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.

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:
