Building a 3-tiered Application with Java EE

Do you want an expert to walk you through the key features of Java EE 7? At the next OTN Virtual Technology Summit (VTS), Java expert and author Josh Juneau will walk you through building a 3-tiered application with Java EE. He will take you step-by-step through the development of an application using Maven. You will learn how to add project dependencies via Maven, and perform various development tasks leveraging some new features of Java EE 7.  

During the development of this application, Juneau will touch upon a handful of the Java EE technologies:

  • creation of views using JSF and PrimeFaces
  • binding to managed bean controllers via CDI
  • utilization of the Batch Processing API
  • JMS
  • WebSockets

At the end of this VTS session, you will have a better understanding of how a typical Java EE application is developed. You will also know how to implement solutions using some of the latest features of Java EE.

Note: This a hands-on lab that requires you to have the following downloaded and installed *before* the session:

  1. Java EE 7 SDK Update 1 with GlassFish 4.1: Oracle Technology Network  
  2. NetBeans IDE 8.0.1:  https://netbeans.org/
  3. GlassFish Hand-on-Lab:  https://glassfish.java.net/hol/
  4. MoviePlex Starting Sources:
    https://glassfish.java.net/hol/movieplex7-starting-template.zip 

The Virtual Technology Summit (VTS) are interactive, online events, sponsored by the Oracle Technology Network (OTN). VTSs are free, but you must register:

Each 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.

Java SE 8 on Java.com

With the release of Java SE 8 Update 25, the Java SE 8 runtime is now available on java.com as the default JRE for end-users. The process of migrating users from Java 7 to Java 8 through the auto update feature is expected to take place during the first quarter of 2015.

As outlined in the Oracle Java SE Support Roadmap, after April 2015, Oracle will no longer post updates of Java SE 7 to its public download sites. While existing Java SE 7 downloads will remain accessible on Oracle Technology Network, developers and end-users are now encouraged to begin the transition to Java SE 8.

Customers who need continued access to critical bug fixes and security fixes as well as general maintenance for Java SE 7 or older versions can get long term support through Oracle Java SE Support.

Thanks to Henrik Stahl, VP of Product Management in the Java Platform Group at Oracle, for this information in his blog "Moving on to Java 8."

Interactive Java Tech Content Delivered to Your Desk

The Virtual Technology Summit (VTS) delivers interactive Java tech content from Java Champions and Oracle experts to your desk.  

These interactive, online events, sponsored by the Oracle Technology Network (OTN), are coming in November:

Each event feature 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.

The Java Track includes three code-heavy sessions: 

Transform Your Code to Java 8
by Venkat Subramanian, Java Champion

The new facilities in Java 8 are about to change the way we write code. Our code will become more expressive and concise. But exactly how? This presentation takes several common Java code examples, discusses the core idea expressed in the code, and transforms that code to use the facilities in Java 8. Watch and interact as you see Java code go through a weight loss program right in front of your eyes.

Java Mission Control for Earthlings
by Jim Weaver, Java Evangelist, Oracle

Java SE Advanced contains an application named Java Mission Control, which consists of two facilities essential for developers and IT production support.  These facilities are JMX Console and Java Flight Recorder, both of which help you monitor applications and tune them for high performance.  This session will present features of Java Mission Control, as well as relevant concepts.

Exploring Java EE
by Josh Juneau, Tech Writer and Author

The Java EE tutorial will walk users step-by-step through the development of an application (MoviePlex) using Maven. The development will take place within NetBeans 8.x IDE, it will demonstrate how to add project dependencies via Maven, and perform various development tasks leveraging some new features of Java EE 7.  We’ll delve into the creation of views using JSF and PrimeFaces, binding to managed bean controllers via CDI, utilization of the Batch Processing API, JMS, and WebSockets.  In the end, you will have a better understanding of how a typical Java EE application is developed, and how to implement solutions using some of the latest features of Java EE. Note: This a hands-on lab that requires you to have Java EE and the NetBeans IDE downloaded before you attend the session.

We'll kick off the track with Java Community Update by Tori Wieldt. There will be places to hang out and meet other attendees between sessions. View the full agenda, abstracts, and participation instructions on the VTS Event Resources Community Space. Plan to be there!

Java SE 8 Update 25 and Java SE 7 Update 71 and 72

Oracle has released Java SE 8 Update 25 and Java SE 7 Update 71 and 72. Developers can download the latest Java SE JDK and JRE at the Oracle Technology Network.

Java SE 8 Update 25

This release includes important security fixes. Oracle strongly recommends that all Java SE 8 users upgrade to this release. Read the Release Notes. Download Java SE 8 Update 25.

Java SE 7 Update 71/72 

These releases includes important security fixes. Oracle strongly recommends that all Java SE 7 users upgrade to one of these releases.

What is the difference between a Java CPU (7u71) and PSU (7u72) release?

Java SE Critical Patch Updates (CPU) contain fixes to security vulnerabilities and critical bug fixes. Oracle strongly recommends that all Java SE users upgrade to the latest CPU releases as they are made available. Most user should choose this release.

Java SE Patch Set Updates (PSU) contain all of the security fixes in the CPUs released up to that version, as well as additional non-critical fixes. Java PSU releases should only be used if you are being impacted by one of the additional bugs fixed in that version.

Read the Release Notes. Download Java SE 7 Update 72/71.

Silicon Valley Code Camp for Kids 2014

by guest blogger Arun Gupta

300+ kids, 16 speakers (4 from middle/high school), 6 rooms, 24 sessions of 75 mins each = extremely rewarding weekend + inspired kids!

And the name is Silicon Valley Code Camp 2014 Kids Track.

300+ kids, wow! Is that the biggest known event focused on getting kids excited in technology ? 

The event covered topics ranging from Minecraft modding, Building your first iOS app, Raspberry Pi, Arduino, Python, LEGO Mindstorms, Scratch, Squishy Circuits, and a whole lot more.

Many thanks to all the attendees, volunteers, parents, and of course Silicon Valley Code Camp organizers, especially Peter Kellner (@pkellner) for providing all the support to educate and inspire kids!

We’d love to have your kid deliver workshops for us next year. Help us increase the young presenters more. We’d also love female presenters, help us create gender balance in this otherwise imbalanced industry :-)

We’ll be back next year, bigger and better. Feel free to leave feedback on my blog.

Are you interested in opening a local Devoxx4Kids chapter in your city ?

Join www.meetup.com/Devoxx4Kids-BayArea if you are interested in an event that provides technology workshops for kids through out the year.
