JavaOne Rockstar Speaker Hendrik Ebbers

In a Java Magazine article, senior Java architect Hendrik Ebbers talks about his JavaOne sessions and JavaOne. "There will be some very cool JavaFX, community, open source and Internet of Things talks this year. The talks are always very professional; I have never experienced a bad one. So don't miss the talks" he explains.   

Hendrik focuses on research and development, Swing, JavaFX, middleware and DevOps. He wrote the book titled "Mastering JavaFX 8 Controls" and will present six JavaOne sessions:   
  • Smart UIs for Mobile and Embedded in JavaFX introduces a new JavaFX theme that is made for embedded devices and will fit perfect in all the cool new Internet of Things and mobile products. 
  • DataFX: From External Data to a UI Flow and Back shows how the different DataFX components make it easy to manage external data by using well-known Java technologies.
  • Enterprise JavaFX, an overview of various best practices for communication between server and client, async background tasks, MVC approaches, and the designing of complex dialogue flows
  • Extreme GUI Makeover.  JavaFX 8, a new UI toolkit, offers a lot of amazing features to help you craft modern-looking and interactive UIs.
  • The JavaFX Community and Ecosystem introduces the JavaFX ecosystem including third-party frameworks and popular knowledge base. It also illustrates the functionality and synergy effects between the libraries with a live coding session. 
  • Test-Driven Development with JavaFX

Why Another MVC?

In this new article, JavaServer Faces (JSF) spec lead Ed Burns explains two kinds of model view controller (MVC) as part of the JSF framework. The article's goal is to show the continued commitment to JSF evolution and to clarify the complementary usages of these two view technologies.


The two kinds of MVC in question are UI component oriented MVC and action oriented MVC. This article first goes over these two different styles of MVC, then explains the rationale for filing a separate JSR for MVC 1.0 and explains how this new specification will relate to the next version of JSF. 

If you attend JavaOne, you find many JavaOne sessions about JSF

Interview with Nikita Salnikov-Tarnovski

Nikita Salnikov-Tarnovski is the co-founder of Plumbr, the memory leak detection product. Besides his daily technical tasks he is an active blogger, a JavaOne RockStar and a frequent conference speaker at Devoxx, JavaOne Russia, 33rd Degree, TopConf, JavaDay, GeekOut, Joker, and Jazoon.

Q: What are your JavaOne sessions about this year?

Salnikov-Tarnovski: My two talks are about identifying and solving memory leaks in applications, one conference session titled “keep memory leaks at bay” and one tutorial called “where is my memory.” Both sessions relate to how Java applications consume and use memory while running. I will discuss how to monitor your production environment; how to detect memory leaks and other memory inefficiencies; what to do if your application fails because of memory leak or becomes unbearable slow due to Garbage Collection taking too long, and so on.

Q: Are you giving tips and tricks during those sessions on how they can use Plumbr’s product?

Salnikov-Tarnovski: Last year, I talked about Java memory leaks and I used our product to present solutions. This year, I will talk about general methodology and techniques on how these problems can be detected and solved with the aid of the best tools on the market including our tool and any other freely available tools.

Q: Why are memory leaks important?

Salnikov-Tarnovski: Memory leaks are one of the top reasons why Java applications crash in production. Other memory related problems, such as inefficient Garbage Collection can make your application just stall for some arbitrarily long time. And your clients will be effected. E.g. when you hit the search button on Amazon.com and this all of a sudden takes too long, it is probably because GC kicked in and said: “Wait some 10 seconds, I will look for some garbage”.

Q: Aside from your sessions, what do you have planned for JavaOne?

Salnikov-Tarnovski: The main reason why I attend conferences - apart from talking about our product, of course – is to meet the many bright speakers and attendees. When you're a senior engineer with 12 years of experience, you want to go to conferences like JavaOne to meet your peers - people who are smarter than you- because you can learn a lot from them. You can discuss your problems and get feedback, and share your ‘war’ stories. This is the main reason why I attend conferences and I advise all my fellow engineers to go to JavaOne and other Java conferences. I'm planning to go to Java conferences as long as I am in this profession.

Java and Security at JavaOne

In a Java Magazine interview, Jim Manico (pictured on the right) describes his JavaOne session on security. "I will be speaking about the top coding techniques and essential tools, including several Oracle Open Web Application Security Project (OWASP), Apache, and Google open source Java projects that will help developers build low-risk, high security applications". Jim is an author and educator of developer security-awareness training. You can find more details of his session in JavaOne content catalog

His session is part of a dedicated track about Java and Security, which addresses topics ranging from security tools and coding techniques to innovative products, and includes participation from recognized security leaders discussing policies and best practices. While the value of offensive security techniques is recognized, the focus of this track is primarily on defensive measures.

JavaOne Hackergarten (and Others Worldwide)

by guest blogger Andres Almiray

It's with great pleasure that I announce JavaOne will host a Hackergarten this year once more. That's right, you did read it well, the name sticks, we're no longer renaming it to CodeGarten like last time ;-)

At JavaOne 2014, the Hackergarten has a dedicated space at the Java Hub in JavaOne exhibit hall, Hilton Union Square. The space has power, a private Internet network, white boards, and seating for 16. Attendees need to bring their laptops. You may stay as long as they want, from less than an hour to most of the three days. The format remains the same as other Hackergartens. Participants will contribute to open source projects. 

The idea is to gather people around specific topics at the scheduled times. Topics range from Java SE, Java EE, JSRs, pretty much anything Java-related. Contributions can be production code, test cases, documentation, or simply a friendly chat in order to gather feedback. If you want to host a session (help people to work on an open source project), please contact me. The project page is here and will be updated as we fill out the schedule.

We are also running Hackergartens at other conferences. The following ones are already confirmed:

JCrete - Aug 25th (in English)

JavaZone - Sep 9th (in Norsk & English)

JMaghreb - Nov 6th (in French)

Learn more about Hackergartens at Hackergarten.net.

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
