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

Can't decide which sessions to attend? Check out Ed Burn's picks

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.”

Free Open Source Tools for Maven, HTML5, IoT, and Java EE

Are you struggling with being productive in Maven, HTML5 frameworks such as AngularJS, IoT hardware such as the Raspberry Pi, or Java EE? Do you want free, easy to use, out-of-the-box tools for quickly and efficiently developing all kinds of applications? You really need to give the NetBeans IDE a whirl! At the next Virtual Technology Summit,  OTN will show you the latest enhancements and cool features of the free, open-source NetBeans IDE, which are used around the world, from engineers at Boeing and NASA to Java architects such as James Gosling and Stuart Marks! This is one of four Java sessions of the OTN Virtual Technology Day. Other topics include JavaScript on the JVM, Java Application Monitoring and Java Wearables.

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.

Java Magazine: Platform for Innovation

Tools make the cloud. To support modern development, today’s cloud development environments must support the full software development lifecycle. Developers working in the cloud need tools for builds, continuous integration, source control, and team collaboration. With those tools at the
ready, they can take advantage of the cloud as a platform for innovation.

In our interview with Mike Lehmann, vice president of product management for Oracle Cloud Application Foundation, we explore Oracle’s Java-based cloud services for developers, and the benefits they offer. “Taking a new business idea and building an application to support it can be done much more quickly and with lower risk than in the past,” says Lehmann. Read the interview for his insights on Oracle Java Cloud Service, Oracle Developer Cloud Service, and other services that give developers an end-to-end Java development and deployment environment.

Ready to test out these services? Don’t miss Hardshad Oak’s article, “Get Started with Oracle Developer Cloud Service.” Plus, Bert Ertman shows you how to build modular cloud applications in Java.

It’s a new year, and a time when people traditionally think about self-improvement. If you are looking to raise your job prospects and expand your network, Bruno Souza and Edson Yanaga have just the plan for you, and it includes code, community, and— yes—cloud. Their action items will help you to raise your possibilities for the future.

Read all about it in the current issue of Java Magazine!
