New Java Champion: Sven Reimers

Congratulations to the new Java Champion Sven Reimers!

Sven is based near Lake Constance in Germany, and works as a systems engineer at Airbus Defence and Space. He has more than 15 years of experience building complex software systems, and more than 14 years experience with Java. In 2009, Sven was the winner of the Duke's Choice Award in the Network Solutions category for ND SatCom Satellite Communication Management Software.

Besides his day job, his contributions to NetBeans got him elected to the NetBeans Dream Team in 2008. He is a community leader for NetBeans, a founder of the Java User Group in Bodensee and a contributor to OpenJFX. Sven has been very active as a public speaker at multiple conferences, events, JUGs all over the world. e.g. JavaOne (SF/Brasil), SvJUG, JayDay, NetBeans Days, JFokus, and JCrete.

He is an active contributor and participant at the Hackergarten events. In the interview below, Heather VanCura interviews Sven and Andres Almiray at Devoxx 2014 

Java Champions are an exclusive group of passionate Java technology and community leaders who are community-nominated and selected under a project sponsored by Oracle. Learn more about Java Champions.

JavaLand Conference Offers Thrills

Java developers, architects, strategists, administrators, enthusiasts, and project managers will meet at the JavaLand Conference in Germany March 24th-26th, 2015. Program Leader Markus Eisele explains "JavaLand 2015 will be all about Duke's 20th birthday. We are looking back at 20 years of Java and a big part of this is to engage the vibrant community as we experience it today. It's going to be a packed schedule covering all of today's Java use in the wild."

There will be a keynote by Marcus Lagergren, Oracle Java Engineer. He will recount the phenomenal development of the Java world since 1995 and muse about Java’s future. JavaLand also includes a training day, including deep dives on NoSQL for Java Developers, Java 8: Practical Streams and Lambdas, Java EE 7 from and HTML5 Perspective and JavaScript for Java developers. There will be lots of community activities, including a Java Innovation Lab and Hackergarten

An extraordinary aspect about JavaLand is the venue. The conference happens in an amusement park!  After sessions, you can enjoy the rides of Phantasialand. For example, the Black Mamba is a roller coaster that goes 80 km/h. The JavaLand team says “We want to see your brains on fire and your bellies well filled. We want to you experience inspiring talks about Java technologies and hear you scream when you ride the Black Mamba.”

Getting Started with Embedded Java -- Sense, Control, Connect, Store, Sync

At JavaOne 2011, Terrence Barr, Senior Technologist, Mobile & Embedded, Oracle Germany, presided over a two-hour HOL (Hands-On-Lab) on Monday in which he taught developers how to build an embedded Java solution that senses and controls the environment, stores data, and connects to back-end databases for synchronization and further processing. The session offered considerable detail along with step-by-step exercises as participants learned how to create the embedded EnviroTracker system and application which tracks and processes environmental data. The application interfaces with a microcontroller to read sensor input (ambient light brightness), to control output (and LED), and then further processes the sensor data.

The lab focused on:
• The benefits of Java technology in the embedded space
• The components of embedded Java platforms
• Setting up an embedded Java platform
• Interfacing between the embedded Java platform, the microcontroller, and I/O
• Accessing and controlling I/O from Java
• Processing sensor data

Barr took developers through seven basic tasks or exercises:

1. Create the EnviroTracker
2. Install the OJEC (Oracle Java ME Embedded Client) on the Development Host
The Oracle Java Micro Edition Embedded Client (OJEC) implements the CDC Platform configuration.
3. Develop and Test Your First Embedded Java Application..
4. Install OJEC on the Target Platform and Run Your Java Application
5: Understand I/O and the Arduino Microcontroller
6: EnviroTracker V1: First Contact
7: EnviroTracker V2: Continuous Monitoring and Processing

By the end of a rigorous and demanding, but satisfying two hours, attendees had built a real-world embedded system and created the EnviroTracker Application to track environmental sensor data. They learned how to install and use embedded Java runtimes and tools, and how to interface with I/O devices and microcontrollers from Java applications.

The take home message: Creating sophisticated embedded Java systems and applications is easy due to the platform independence of the Java language and runtime, the scalability of pre-existing Java skills to embedded development, and the comprehensive support provided by mature and feature-rich developer tools.
