JavaLand is a community conference in Germany that is held in an amusement park. Come learn not only about Java and technology, but also about how geeks have fun!
We will have a live NightHacking stream running from the Java Community Area on Tuesday and Wednesday with an all-star interview line-up. Each day will also conclude with an exciting combined vJUG session, which you won’t want to miss!
Schedule (Time Zone is CET)
If you haven't looked at the NetBeans IDE lately, you'll be blown away by the fast speed and performance enhancements. If you are completely new to the NetBeans IDE, see how easy it is to get started and be productive. For example, did you know NetBeans can refactor all your code from Java SE 7 to Java SE 8? See how in this session, lead by NetBeans expert Geertjan Wielenga.
Virtual Technology Summits (VTS) are interactive, online events, sponsored by the Oracle Technology Network (OTN). VTSs are free, but you must register:
• EMEA – 25 February - 9:00 to 13:00 BST REGISTER
• APAC – 4 March – 9:30 to 13:30 IST REGISTER
Each OTN VTS features four technical tracks, each with a unique focus on specific tools, technologies, and tips: Java, Database, Middleware and Systems. Registration allows you to attend any session on any track. We'll kick off the VTS with Java Community Update by Tori Wieldt. There will be places to hang out and meet other attendees between sessions. Please join us!
Q: What have you been programming lately?
Q: And you won an award for it...
Q: How would you advise young girls to get started in programming?
Q: How easy was it for you to get started?
Q: What do you like about Java?
Q: What would you like to do as a career?
Hear from Trisha Gee and Regina Ten Bruggencate as they share tips and tricks to help women and new speakers get started. They themselves are veteran speakers, members of program committees and community leaders for user groups and the Duchess organization, a community of technical women.
Java is everywhere. As the Internet of Things (IoT) moves from hype to reality, we’re seeing embedded Java used in a wide range of applications, from industrial automation systems and medical imaging devices to connected vehicles and smart meters. In the November/December 2014 issue of Java Magazine, we bring you the latest on Java and the IoT.
In our interview with Oracle’s Henrik Ståhl, we discuss the opportunities and challenges that the IoT presents for Java developers, and how changes in Java SE and Java ME (and their embedded versions) make it easier to reassemble and strip down code for smaller devices.
We also talk to Freescale’s Maulin Patel about the IoT and Java, profile IoT Developer Challenge winner Lhings Connected Table, and show you how robots make factories smarter. Plus, Vinicius Senger introduces the Device I/O API, Kai Kreuzer brings us the latest on smart homes, and Michael Kölling shows us how to program in Java on the Raspberry Pi.
Plus, we take a look at the developers of tomorrow in “Java: the Next Generation.” I’ve been talking to kids at various programming events for the last few months, and I am inspired. These kids are brave, bold, and so smart. They do not fear technology; they embrace it. I’m thrilled to see so many programs around the world that are teaching young people to code and helping them to create their futures.
Read all about it in the current issue of Java Magazine!
The biggest Java developer conference in Europe started today with two days of University Sessions, 3 hour labs on various Java topics.
The sessions from Oracle speakers during those two days are:
Monday, November 10
Tuesday, November 11
On Tuesday, attendees will get the chance to work on open source projects such as JSRs with the help of veteran contributors and spec leads at the Hackergarten.
Starting tomorrow at the Oracle booth, enter the raffle for a chance to win a Raspberry Pi. Three Raspberry Pis will be raffled off every day. Don’t miss the beer bash late in the afternoon on Tuesday and Thursday.

At the Java Hub, Java’s flexibility was illustrated through a number of demos and displays. The message was clear: any Java developer can program in Java Embedded, so get your Raspberry Pi, connect it to your favorite device, and have fun with the Internet of Things (IoT). Aldebaran Robotics presented the friendly, 2-foot-tall, high-tech Nao robot, which can be used to enhance social awareness among autistic children. It danced, gave fist bumps, and seemed to drink in the attention. Across the room, a 3-D printer performed its magic, creating clones of Duke using JavaFX and Oracle Java Embedded.
James Gosling’s Wave Glider
A Liquid Robotics Wave Glider, with software developed by James Gosling, was also on display. Wave Glider, which looks like a souped-up yellow surfboard, is an autonomous water and solar-powered platform that transmits oceanic information such as water temperature and chemistry, wind speed, living organisms, and ocean bottom topography using Java SE Embedded applications for defense, oil and gas, and commercial and science customers.
Wave Glider has two parts, the surfboard-like “float” loaded with solar panels to recharge lithium-ion batteries—which resides at the ocean’s surface—and the sub, equipped with wings and tethered six meters below.
Java Capabilities for the Green Power Industry
Alexander Belokrylov, product manager for Java ME Embedded, showed off Java ME capabilities for the green power industry, demonstrating how a Java ME Embedded application can control and monitor energy sources on a bicycle-driven electric generator.
“This is just a regular bicycle that illustrates the Raspberry Pi functionality,” explained Belokrylov. “Here it is connected to a bicycle, but it could also function with an irrigation system or many other things. The key point is that with Java ME and no libraries, we can run a fully autonomous system that connects to the cloud and measures energy usage. This is a small footprint and it can do a lot. We want Java developers to take this power and run with it!”
A Car that Knows You
Gary Collins, principal member of technical staff at Oracle, showed off the Telematics Car Demo from Sunday’s Java Strategy keynote, where a simulated electric car used Java ME Embedded data and JavaFX to aggregate and display temperature, speed, light sensor, crash, and other data. “The functionality enables a car to make adjustments for drivers,” explained Collins. “Suppose you drive this car from a rental agency and come back to rent it again. The agency can access data about you and adjust the car for temperature, seating position, preferred radio stations and many other applications. It’s a car that can learn your preferences and patterns.”
Playing with Java SE Embedded
Across from the car simulator, a row of Raspberry Pis interfaced with cubed light bulbs, Sphero Robotic Balls, XY-Plotters for drawing, and more. Attendees were invited to choose an “if statement” and then tweet, send an SMS message using a motion or light sensor, draw their names with a Java or Oracle logo or picture of Duke, and more. Light bulbs could light up in strange ways; a Sphero Ball could act crazy. It was all in the spirit of play to illustrate that Java SE Embedded offers a wide range of possibilities for developers who want to try out the IoT with Java 8.
In Strategy keynote, you will learn how to create the future with Java from leading Oracle experts in the Java development organization. They will showcase how Java is driving developer innovation, revolutionizing application development, and improving application services for IoT, enterprise architectures, and cloud computing.
In the Technical keynote, the architects of Java 8 will give you their insights into this revolutionary release, and start to reveal what is coming in Java 9, Java 10, and beyond.
“Being able to debug and profile robots out at sea is a truly life-altering experience,” Gosling explains. He uses a set of tools—consisting of editors, debuggers, and profilers—that are part of the NetBeans IDE. At the JavaOne 2014 NetBeans Community Day, he will present the session “James Gosling, Robots, the Raspberry Pi, and Small Devices” [UGF8907] on Sunday, September 28. He will also present “Debugging and Profiling Robots with James Gosling” [CON6699] on Wednesday, October 1. Geertjan Wielenga, Mark Heckler, José Pereda, Johannes Weigend, Shai Almog and Jens Deters will join him to discuss those two topics.
Join him as he closes out the JavaOne Community keynote with a fun, historical perspective of the genesis of Java, and a T-shirt toss! The Community Keynote will be held in the Marriott Marquis, Salon 7/8/9, on Thursday, October 2, 2014
