Java Tsunami on the Thames

London prepares for a surge of developer brainpower during the Devoxx UK conference on Tuesday and Wednesday, March 26th and 27th. Meet & Greet, global Java community, and Hackergarten are nice add-ons. Don't miss it - Register today

The fun really starts on Monday evening with an attendee Meet & Greet where attendees can relax, grab a drink and something to eat and, of course, meet fellow attendees and the speakers. 

In addition to U.K speakers, many international guests are scheduled, notably from the US. Twenty-eight user groups from across Europe are attending too. A veritable army of experts will be on hand to share their expertise with Devoxx attendees.  

Hackergarten takes place during the conference. There's no time limit; participants can stay and code for as long as they want. Just bring a laptop and write a plugin, a tutorial, a small feature, or a bug fix for a project that interests you alongside several open-source experts willing to share their knowledge. The organizers of two community projects called Adopt-a-JSR and Adopt Open JDK will be there to explain how to contribute to the future Java releases. 

Java in the Internet of Things

In this video, I talk to Product Manager for Small Embedded Java Terrence Barr at Embedded World. He gave presentations that included the slide that said "Stop Reinventing the Plumbing." I asked him what that means:

Java already has the connectivity, manageability, interoperability, and back-end integration you need for apps, so you can concentrate on your area of expertise, your "value add" on top of that plumbing. Java -- saving the world, one developer, one sensor at a time. ;-)

Java EE 7 Open and Transparent

In his blog titled "Transparency and Community Participation in Java EE 7", Java Evangelist Arun Gupta explains the "high level of transparency for all of the Java Specification Requests (JSRs) under the Java EE 7 umbrella" and the increase of up to 7.5x participation by Java developers from previous releases. 

Since October 2011, JCP 2.8 has set eight new transparency rules for all new projects. The rules require the disclosure of such information as Expert Group member information, technical discussions, public feedback, JSR schedule, RI and TCK processes, and public documentation. Arun shows how the transparency rules apply to the JSR 342 project. 

About 20 Java User Groups (JUGs) from around the world contributed to the fourteen Java EE 7 JSRs. In many cases, the JUGs involved contributed to several JSRs via the community run initiative Adopt-a-JSR.

Arun lists JUGs events, their presentations and the code they contributed as a results of those events. They are great examples for other JUGs to get involved. Java EE still has projects open and Individuals as well as JUGs can contribute in three steps: join a JUG, participate in Adopt-a-JSR, choose a Java EE 7 JSR.

Yours Truly Generating Data

Ever pay to have someone watch you sleep? I have. It's not as kinky as it sounds; because of my loud snoring, my spouse insisted I get a sleep study. There I was, in a room with a camera, hooked up to a diagnostic sleep system. I had sensors attached to my head, neck, legs and chest. I even had an ET finger that glowed red (a sensor using light to determine how much oxygen was in my blood). And what was I thinking about as I drifted off to sleep? The data I was generating! Where was it going? What format was it in? Who wrote the app?

There is lots of data being generated by medical devices currently, and much, much more to come. The number of mobile connected devices is expected to increase by 100% to nearly 12 billion by 2020; resulting in a market opportunity of $1.2 trillion. Now what? Where does the data go? What format does the data need to be in? Will developers have to write an different app for every device manufacturer? Java to the rescue! Manfred Kube, Director of Business Development, mHealth, for Gemalto Systems explains, "Through the power of Java, we are enabling medical devices to  connect to cloud in a standard-based, interoperable fashion, and avoid the silos that are common today." See how Java makes it easy to get started and be successful in mHealth:


The GMSA supports standards throughout the mobile world, and is taking the lead in M2M standards. To accelerate and simplify mobile health application development, the GMSA is partnering with the Continua Health Alliance, whose mission is to developing design guidelines that will enable vendors to build interoperable sensors, home networks, telehealth platforms, and health and wellness services.

Java Save Lives at Mobile World Congress

Mobile World Congress used to just be about mobile phones and the industry around mobile networks. Now "mobile" has redefined itself and is about sensors everywhere: cars, scooters, buildings, people, etc. The M2M (or "Internet of Everything") revolution is here, with mobile phones as just one of the many components that create an intelligent, connected world. As the mobile industry moves its focus from voice to data, developers now have the entire world as a potential for apps. The world is literally your oyster (sorry, had to).

With all this opportunity comes decisions to make. Todays' developers have a wide range of choices in terms of what device they are going to use and how to control it. How smart is the device? Do you want it to be tailored and tuned to a specific solution or something more broad? How do you get the data from the device to the data center? The device and platform you choice are key components for a successful implementation. Java has been on devices for a long time: smart cards, cars, ATMs, phones, underwater probes, and more. Java enables devices to be intelligent, scalable and supportable. Want to update a device remotely? Done. Want it to be headless? Done. Want a remote sensor on your grandmother that calls the hospital if she falls, and also lets the paramedics open the door to her house? Done. Here's video that shows Java saving grandma's life at Mobile World Congress:

If you are at MWC, drop by the Oracle booth and learn more. You also have a shot at winning a Raspberry Pi at WIPJam @ MWC 2013 event for mobile developers Thursday evening. See how Oracle and Deutsche Telekom have made it possible to make your coffee by phone, by combining a coffee machine, a Raspberry Pi, Java SE and the Deutsche Telekom network. M2M can deliver your favorite brew (and programming language and platform)!

Arun Gupta on Higher Productivity from Embracing HTML5 with Java EE 7

Oracle’s Java evangelist and noted Java EE expert, Arun Gupta, presented a session at the annual IOUC (International Oracle User Community) Summit, held January 14–16, 2013, at Oracle headquarters in Redwood Shores, California, where more than 100 top user group leaders from around the world gathered to share best practices, provide feedback, and receive updates from leading Oracle developers.

Gupta’s talk, titled "The Java EE 7 Platform: Higher Productivity and Embracing HTML5," presented a glimpse into the rich possibilities that will be available in Java EE 7 upon its release in the spring of 2013. He covered several major developments, including:

* Java API for RESTful Web Services 2.0
* Java Message Service 2.0
* Java API for JSON Processing 1.0
* Java API for WebSocket 1.0
* Bean Validation 1.1
* Batch Applications for the Java Platform 1.0
* Java Persistence API 2.1
* Servlet 3.1
* Concurrency Utilities for Java EE 1.0
* JavaServer Faces 2.2

Gupta focuses on ways in which Java EE 7 offers higher productivity; less boilerplate; richer functionality; more default options; and HTML5 support in the form of WebSocket and JSON. He also observed that the cloud is in need of more standards. From the article:

"There are not enough standards in the cloud with W3C and other standards bodies. More standards are needed so that we can define a Java API for the cloud. Premature standardization can also be a problem if not enough innovation has taken place. So what is the right thing for the platform? We have reached out to the community, the core group members, and the executive committee of the Java Community Process and have focused on providing higher productivity and on embracing the HTML5 platform more closely. We are going to use dependency injection a lot more, which will give developers the ability to write less boilerplate code and offer richer functionality such as batch applications and caching. Similarly, for HTML5, we are embracing WebSocket functionality and the ability to parse and generate a JSON structure. We are providing support for HTML5-friendly markup as part of JSF.”

Gupta summarized the strengths of the various JSRs and closed by encouraging developers to participate in Adopt-a-JSR, a project that enables them to, “pursue their interest in particular Java EE 7 JSRs and download code, play with it, report bugs, and offer feedback to Java EE 7 specification leads.”

Updates to February Critical Patch Update for Java SE

Oracle has released Updates to February 2013 Critical Patch Update for Java SE. This update contains fixes for additional security vulnerabilities. Oracle recommends that customers apply Critical Patch Updates (CPUs) as soon as possible. You can read details on the Oracle Software Security Assurance Blog.

Released today is:

Auto-update and Manual Update of JRE 6 will Replace JRE 6 with JRE 7

Since JRE 6 has reached its End of Public Updates, Oracle is taking steps to protect consumer desktops. Oracle will not leave a version of Java installed for which Oracle no longer provide security updates. 

In order to do so, when updating from JRE 6, the update mechanism will not only install the latest version of JRE 7 but will also remove the highest version of JRE 6 on the system. This change will happen when the system is updated via the auto-update mechanism or by checking for updates directly from the Java Control Panel. For more information, read the Java SE 7 Update 15 Release Notes.  

As always, consumers can get the Java Runtime Environment (JRE) from Java.com. Developers can get the Java Development Kit (JDK) and the Java Runtime Environment (JRE) from the Oracle Technology Network.
