Ashwin Rao on HTML5/NetBeans 7.3

As you may know, NetBeans 7.3 is creating quite a buzz in the community. The 122th episode of the Java Spotlight podcast features an interview with NetBeans Group Product Manager Ashwin Rao. Although he generally keeps a pretty low profile, Ashwin is one of the key folks driving NetBeans forward. He talks with Roger Brinkley about the HTML 5 landscape, the new features in NetBeans such as excellent JavaScript editing capabilities powered by the Nashorn engine on par with the Java editor, support for JavaScipt/HTML 5 frameworks like JQuery, AngularJS and backbone.js as well as enhanced browser integration.

 

 

The podcast also covers Java SE 6, Java EE 7, JavaFX and JavaOne India. You can listen to the full podcast here. If you are hungry to learn more about NetBeans 7.3 after you listen to the podcast, you can check out the list of new features and a cool video on the release.

Peru is also aware of Java EE 7!

IT in Latin America is not only about Brazil and Argentina (and their rivalry on soccer). The IT industry is also strong in other countries such as Chile, Colombia, Uruguay, Venezuela, and others. So I  was in Peru on January 30th to present what's coming on Java EE 7.

 As I'm not so fluent in Spanish (yeap, Portuguese is not Spanish, sorry), I used slides in Portuguese and talked to the ITP_Java community using some sort of dialect in Brazil called "Portuñol". Attendees could learn Portuguese from the slides, and I could learn Spanish from them. It was an exciting experience for everyone! Language exchange and Java EE 7 learning!

Check my blog post for more details about the trip I did to Peru.

 If you are a Java developer and you live in Lima or in the surroundings, don't miss this Hackaton on March 16th! Jose Diaz will be talking about HTML and the Adopt a JSR program, specially the JSRs for WebSockets and JSON. 

Primer Hackaton Adopta un JSR: JSON, WebSockets y HTML5
¿Que veremos?

Usaremos Glassfish 4 y JSR 353(JSON) y 356(WSt), y HTML5 Websocket, Local Storage, web workers, forms y geolocation APIs. Y finalmente como hacer unit test de las implementaciones.

By the way, what do you think about Peru's Java mascot? Too green?

SouJava JUG meeting at Oracle Brasil

On Thursday Feb 21th, Oracle Brasil welcomed the SouJava JUG to its new Oracle Office in Sao Paulo. SouJava does several meetings across different places. Companies like Red Hat, Google, and GlobalCode already offered their offices for previous meetings. Bruno Souza was there to talk about the importance of the Adopt a JSR program and the participation of JUGs on the Java Community Process. SouJava voted Yes on the recent Public Review for JMS 2.0.

To bring attention to the launch of Java EE 7 and its new specifications, I presented "The new features of JMS 2.0" (pt_BR), basically the same content as Reza Rahman presented during JavaOne Latin America (but this time, in portuguese; until Reza doesn't become fluent). There was also a presentation from Ricardo Ferreira talking about In-memory Data Processing with Elastic Data Grids, an introduction to highly scalable architectures, with a demonstration using Coherence, GlassFish and WebLogic. His presentation was also in portuguese.

I gave Google+ a try and used Google+ Events to schedule and invite developers from everywhere and used the Hangout feature to chat and live stream the meeting. You can see the recording on YouTube. Don't forget to also visit our GlassFish community on G+!

Java EE 7 Schema Namespace Moving to jcp.org

The schema namespace for Java EE 7 APIs are moving from java.sun.com to now perhaps a more fitting xmlns.jcp.org. You are encouraged to take a look at the latest Java EE 7 draft schemas at: http://xmlns.jcp.org/xml/ns/javaee/index.html (it is still a work in progress since as you know, Java EE 7 has not been finalized yet). Some of the updated schemas include:

  • application_7.xsd
  • application-client_7.xsd
  • connector_1_7.xsd
  • ejb-jar_3_2.xsd
  • javaee_7.xsd
  • jsp_2_3.xsd
  • javaee_web_services_1_4.xsd
  • javaee_web_services_client_1_4.xsd
  • web-app_3_1.xsd
  • web-common_3_1.xsd
  • web-fragment_3_1.xsd
  • web-facelettaglibrary_2_2.xsd
  • web-facesconfig_2_2.xsd

Independent consultant, ardent Java EE advocate and long-time JCP expert Antonio Goncalves had this to say about the change - "technically changing a namespace is not difficult, so this is not a major Java EE 7 technical update. But it's a symbol. For many years we were wondering what would happen to java.sun.com namespaces. Most of us thought it would be renamed to java.oracle.com. But no, it went back to where it originally belonged, to the JCP. Lately the JCP has moved towards greater transparency (i.e. JCP.next) and having the JCP namespaces strenghens this move."

Note, not all API namespaces will be updated right away since some APIs are not changing in Java EE 7. For example, JAX-WS will likely not be updated. All the older namespaces will continue to be maintained for backwards compatibility.

Now is the time to share your views. Here is the relevant EG discussion: http://java.net/projects/javaee-spec/lists/jsr342-experts/archive/2013-02/message/36.

A Gentle Introduction to the JSF 2.2 Faces Flow

My well-respected colleague and good friend Arun Gupta continues his admirable effort to provide some very early coverage of Java EE 7 features. I thought I'd highlight his blog entry on JSF 2.2 Faces Flows written in this vein.

As many CDI adopters are aware of, Java EE 6 introduced the concept of conversation scopes. The conversation scope is a very simple, lightweight and powerful way of having greater control over application state in workflow-oriented applications (e.g. multi-step wizards). JSF 2.2 Faces Flows takes that concept to the next level by standardizing fairly well-understood workflow modeling concerns that have been been there in ADF Task Flow, Spring Web Flow and Apace MyFaces CODI. The JSF 2.2 Faces Flows are a synthesis of those ideas focused on type-safety, annotations, simplicity and fluency.

In his blog entry, Arun does a good job of explaining the basic concepts. He discusses the feature, explains the motivation, introduces the API, links to a great video demoing the feature and references further resources.

Java EE 7 Maven Repository Coordinates

For those of us doing Java EE development with Maven (which by my own account as a former consultant is pretty much all Java EE/GlassFish adopters), getting our hands on the repository location for Java EE APIs is critically important. You will be pleased to know most of the Java EE 7 APIs are available via Maven already to aid in your exploration and early evaluation efforts.

The GlassFish wiki outlines the Maven coordinates for Java EE 7, Java EE concurrency, JPA 2.1, JAX-RS 2, Servlet 3.1, EL 3.0, JMS 2, JSF 2.2, CDI 1.1, Bean Validation 1.1, JBatch, JSON-P, WebSocket and others. It should be pretty straightforward to use - give me a shout if you need help setting up Maven.

JavaOne 2012 Videos Now on YouTube

Many folks have consistently said that viewing JavaOne videos on the Content Management Tool used by Oracle is not ideal. You will be happy to know that the JavaOne San Francisco 2012 videos are now on YouTube via the Oracle Learning Portal (OLP). The videos are 100% free for anyone to view.

Besides the OLP Landing Page on YouTube, the videos are organized by the JavaOne 2012 Technical Tracks on the following links:

It's really an invaluable set of materials from some of the greatest thought leaders in the Java world. Enjoy!

Java EE/GlassFish/Oracle@Jfokus

The Jfokus conference was held on February 4-6 at the Stockholm Waterfront Congress Centre, Sweden. The conference was a resounding success and has clearly established itself as a formidable presense in the Nordic region. It sold out 2 weeks before the official start with 1550 attendees from 20+ countries.

The Java EE and Oracle presence was very strong in the conference.

Arun Gupta and Markus Eisele delivered a lab on "Developing JAX-RS Web Applications Utilizing Server-sent Events and WebSockets". This was essentially the same lab delivered at JavaOne San Francisco and JavaOne Latin America. The end of the lab also previewed parts of an upcoming Java EE 7 lab. Arun also delivered our flagship Java EE 7 talk titled "The Java EE 7 Platform: Productivity++ and Embracing HTML 5". Arun also talked about the Java EE 7 JSRs in the Adopt-a-JSR program during a talk titled "How to participate in the future of Java".

Other notable Java EE/Oracle speakers included Geertjan Wielenga, Mike Keith, Simon Ritter, Heather VanCura, Mark Reinhold, Terrence Barr, Klara Ward, Sonya Barry, Georges Saab, Justin Lee, Marcus Lagergren, Attila Szegedi, Sharat Chander and Henrik Stahl. Stephen Chin concluded his highly successful NightHacking Nordic Tour at the conference. Dr. James Gosling was a very welcome presense.

You can read more about the conference on Arun Gupta's blog entry, including his slide decks and code. Markus Eisele also blogged about the conferce.

Adopt-a-JSR Follow-up Online Meeting

As you might be aware, the Adopt-a-JSR program was started by the London Java Community and SouJava to encourage more grassroots level participation in the JCP. The idea is for developers to closely engage with a JSR they are interested in through their own JUG. On January 18th there was a pretty sucessful initial online call explaining the details of the program. There were over 40 JUG leaders/members on the call from around the world.

The folks behind the Adopt-a-JSR program are now hosting a follow-up online meetup on February 27th. Anyone can join the meetup to learn about the current JUG Adopt-a-JSR use cases, new developments and provide feedback. Martijn Verberg from the LJC, Bruno Souza from SouJava, Arun Gupta from the Java EE/GlassFish team and Heather VanCura from the JCP program office will be leading the meetup.

A Gentle Introduction to JBatch

As Java EE 7 rolls forward, my good friend and colleague Arun Gupta has been trying to blog about some of the most exciting new features. His blog entry Undertanding JSR 352 Concepts is a great starting point into JBatch (aka "JSR 352" aka "Batch Applications for the Java Platform"). As you may be aware JBatch is an IBM led JSR that's slated to be included into the Java EE 7 platform, but not the lighter weight Web Profile.

Arun explains some key JBatch concepts like Job, Step, JobOperator, JobRepository and the Reader-Processor-Writer pattern, provides some pretty good code examples and points to further resources like the JavaOne JBatch session and the official spec artifacts.

A Visualization of the GlassFish Story

As you might have noticed, we have maintained a steady cadence of pretty serious stuff once a day for the past few months. I thought we should reward ourselves a bit with something a little more lighthearted/offbeat but still pretty cool.

Sometimes a picture does say a thousand words. Key Java EE community member and GlassFish fan Markus Eisele blogged about a neat way of visualizing svn commits over time. He applied this technique to the GlassFish repository - see the results below:

It is a pretty stunning visual representation of the highly dedicted roughly 134 committers continually working on GlassFish to bring you the latest and greatest in Java EE. Enjoy!
