Java EE @ JDK.IO 2014

JDK.IO 2014 was held in Denmark on January 19-20 at the IT University of Copenhagen. It is the yearly conference of 'JavaGruppen', the Danish JUG. The conference sessions covered a variety of Java topics ranging from core Java, Java EE, and JavaFX. Speakers included my colleague David Delabassee, Simon Ritter, Adam Bien, Heinz M. Kabutz, Bert Ertman, Ryan Cuprak, Simon Maple and Markus Eisele.

David covered the Java EE portion of the keynote. He also presented a talk on Java EE 8. His slides from SlideShare are embedded below:

My friend, fellow co-author of EJB 3 in Action, Connecticut JUG leader and JavaOne Rock Star Ryan Cuprak presented a couple of very cool sessions. The first one, titled Hybrid Mobile Development with Apache Cordova and Java EE 7 demonstrates how Java EE can be used as a very effective mobile development back-end using APIs like JAX-RS, WebSocket and JSON-P. The talk was delivered at JavaOne 2014 as a tutorial and includes an excellent end-to-end demo. Video from the JavaOne talk is embedded below:

Ryan also presented another popular talk from JavaOne 2014 - 50 EJB 3 Best Practices in 50 Minutes. At JavaOne he had co-presented the talk with my other co-author Michael Remijan. The video from that talk is embedded below:

Ryan wrote up a very nice trip report of JDK.IO on his personal blog that you should check out. Other Java EE related talks included one by Markus Eisele on Java EE 7 and Apache Camel.

Kito Mann's JSF Sessions at JavaOne 2014

For the Java EE track at JavaOne 2014 we are highlighting some key sessions and speakers to better inform you of what you can expect, right up until the start of the conference.

To this end we recently interviewed Kito Mann. Kito has long been a respected JSF consultant, popular speaker, author and JCP expert. He is the editor-in-chief of JSFCentral.com, co-host of the Enterprise Java Newscast, host of the JSF Podcast interview series, and the author of JavaServer Faces in Action from Manning publications (I met him a long time ago in the process of writing EJB 3 in Action).

Kito has one the highest number of talks from a single speaker in the Java EE track this year. We wanted to talk to him about his JSF sessions at JavaOne 2014, as well as JSF generally:

The following are the sessions we talked about:

  • JSF 2.2 Deep Dive: This tutorial is a two-hour deep dive into all the new features in JSF 2.2 and is probably one of the best bits of training you can have on the technology.
  • PrimeTime JSF with PrimeFaces 5: This session is a look into what is new in PrimeFaces 5, easily the most popular part of the JSF plugin ecosystem.
  • JavaServer Faces Antipatterns and Best Practices: This is an invaluable session if you are a JSF user. Kito shares his wealth of experience as a JSF consultant and navigates the best practices, patterns and anti-patterns for the technology.
  • Mobile JavaServer Faces: This is a deeply well researched session on the available resources for developing mobile applications using JSF. If you are a JSF user being asked to develop mobile functionality, this session is definitely for you.
  • JSF 2.2 in Action: In this one hour session, Kito will overview the features introduced in JSF 2.2 using demos and real life context.

Besides Kito's sessions, we have a very strong program for the Java EE track and JavaOne overall - just explore the content catalog. If you can't make it, you can be assured that we will make key content available after the conference just as we have always done.

Java EE@Pune JUG

Pune JUG organized a meetup at the Symbiosis Institute of Computer Studies and Research (SICRSR) college campus on December 14th. Led by Harshad Oak (Java Champion and organizer of the IndicThreads conference), Pune JUG is the oldest JUG in India and boasts a vibrant developer community. This month's meetup was focused on the Java EE 7 platform and the ecosystem that is building up around it. The meeting was led by Oracle India's own Vijay Nair. Vijay is a good friend and a lead developer with Oracle's FLEXCUBE development group in India. Among many other things like evangelizing Java EE at local Java user groups and conferences, Vijay contributes heavily to the Cargo Tracker Java EE Blue Prints project in his spare time.

 The event saw an attendance of close to around 100 people with a lot of demos/code and high quality interactions with the audience. Vijay presented no less than three sessions at the meetup:

  • JavaEE.Next(): Java EE 7, 8, and Beyond - This is basically our flagship talk at the moment. The talk briefly covers the evolution of the platform, details the changes in Java EE 7 and invites developers to help shape Java EE 8. The materials for the talk is posted here.
  • Android and iOS Development with Java EE 7 - This was a fairly popular technical session at JavaOne San Francisco 2013 led by me, Ryan Cuprak and Bala Muthuvarathan. The session demonstrates how Java EE 7 acts as an excellent platform for building "headless" back-ends for native mobile applications with REST and WebSocket as the client communication protocols. The materials for the talk is posted here. The code is posted on GitHub.
  • Using NoSQL with JPA, EclipseLink and Java EE - This session explores the current state of the NoSQL landscape and how Java EE can be utilized to access NoSQL solutions such as Oracle NoSQL, MongoDB, Cassandra, etc utilizing JPA style facades or plain CDI. The materials for the talk is posted here. The code is posted on GitHub.

Overall, this was a very positive experience with developers giving two thumbs way up to the Java EE 7 platform!

JavaOne 2013 Trip Report

JavaOne 2013 San Francisco was held September 22-26. This was a particularly important year from a Java EE standpoint with the release of EE 7 and GlassFish 4 - the content reflected this fact. JavaOne 2013 can certainly be considered a success by most measures. It's clear the best and the brightest in the Java ecosystem continue to see participating in JavaOne as a badge of honor and a privilege.

Besides booth duty at the GlassFish 4/Java EE 7 kiosk on Monday/Tuesday, I led the GlassFish Community Event on Sunday, had a BOF titled "What’s New with Bean Validation and Expression Language in Java EE 7" on Monday, led the GlassFish BOF on Tuesday and had a technical session titled "Android and iOS Development with Java EE 7" on Thursday. More details on the sessions and JavaOne, including the slide decks and code, posted on my personal blog.

QR Codes for GlassFish.org and TheAquarium

I recently bought my first smartphone and I chose a BlackBerry Tour because it has a keyboard and I wanted to keep up w/ my kid's SMS typing...

The latest goodie for the BB is the BB Messenger 5.0 which can generate and scan PINs encoded as QR Codes. Turns out these codes seem to be extremely popular in some markets and may catch up in the others...

Soo, I generated codes for GlassFish.org (QR Code) and TheAquarium (QR Code). And, if you want to generate QR Codes, I found i-nigma useful.

Symbian Foundation OpenSource Plans

ALT DESCR

Yet another evidence of the value of OpenSource as a collaboration mechanism. Today was the launch for the Symbian Foundation, founded by Nokia, Sony Ericsson, Motorola, NTT DoCoMo, AT&T, LG Electronics, Samsung Electronics, STMicroelectronics, Texas Instruments and Vodafone to unite Symbian OS™, S60, UIQ and MOAP(S) and Open Source the resulting platform (full Press Release).

The group will be using the EPL 1.0 license... and they already have a Wikipedia page.

Added: This story is now being carried by mainstream news: BusinessWeek, InformationWeek, NYTimes.

MobileFaces on GlassFish

Image of a Mobile Phone (Emulator)

Rendering for HTML clients may be the most common use of JSF, but it certainly isn't the only one. In his latest blog entry, Roger shows how to use Ericsson's MobileFaces library and Mobile JSF Kit to serve mobile web applications on GlassFish.

Examples like this show how GlassFish can easily serve up web content for phones. Then we have Sailfin making it possible for GlassFish to (literally) talk to a phone, and the microkernel architecture of GlassFish V3 making people wonder if they'll someday be running GlassFish on their phone.

Anyone noticing a pattern? ;)

NOTD - (NYT) Bar Codes and Mobile Phones

First post in a new category. Notd is like the unix motd, but with "News" instead of "Message". I'll make up the details of the category as I go, but the general topic will be a piece of daily news that seems specially interesting (to me) for one reason or another; let's see how long I can keep it up.

Downtown Tokyo showing one of the new Bar Codes

The NY Times has a piece on the new Bar Codes designed for Camera Phones. The basic idea is that these bar codes will be everywhere in the physical world; you just take a picture of the bar code and the software on your camera will decode it to pull the data from the web. Within this basic premise the possibilities seem unlimited: real-estate information, public transit, retail prices, driving directions, ads in print, etc, etc.

Given the market penetration of camera phones, and the increased network connectiviy, this seems a real winner. As the NYTimes puts it, the cellphone as the universal control. Add some locale awareness, some voice recognition, voice synthesis... The adoption may be very quick, we will see.
