My first speaking engagement at Red Hat started with the visit to a new country – Luxembourg, one of the richest in the world and my 37th!

About 85+ JUG members got introduced to Java EE 7 in a typical slide-free code-driven session. The power of Java EE 7 was quite evident as there was about 20% more than usual attendance. WildFly Beta 1 and GlassFish 4 were used to showcase different samples. This also shows the Write Once Deploy Anywhere (WODA) capabilities of the platform. All samples used in the talk are available at github.com/arun-gupta/javaee7-samples.

The visit got arranged after I hooked up with Nick Mpallas on twitter. He showed very warm hospitality during the short visit and I enjoyed learning about JBoss ecosystem from him. I’m pretty impressed by his prompt pull request to add Arquillian support to Java EE 7 samples.

This was followed by a speaking engagement at JAX London. This is my third visit to this annual conference by S&S Media. (2011 Fall, 2011 Spring). I spoke on two different topics and their slide decks are available:

Java EE 7: Boosting Productivity and Embracing HTML5 from Arun Gupta

 

Getting Started with WebSockets and Server-Sent Events from Arun Gupta

There were ~50 attendees for the platform talk and about ~35 for the WebSocket talk.

In addition, I also spoke at my very first GlassFish Users Group, London meetup as part of JAX London Community Night. Interactive audience and slide-free code-driven introduction to Java EE 7 kept the session entertaining. This was organized by C2B2 Consulting Group who are independent middleware experts based in London. This entire session was recorded and is available:

I had an opportunity to spend some time with Richard Warburton from jClarity – JVM performance analysis and tooling company. They are using Vert.x across different VMs to gather data. Vert.x is a lightweight, high performance application platform for the JVM that’s designed for modern mobile, web, and enterprise applications. More details on vert.x would be available in a subsequent blog but in the meanwhile learn all about jClarity’s usage of Vert.x in this brief interview with Richard:

I also talked briefly with jaxenter.com on my move to Red Hat, wild popularity of the Java EE 7 platform, on what attracts me to JAX London year over year. That interview is also available:

O’Reilly had a booth and was able to sell most of the best-selling Java EE 7 Essentials copies. But you can always order your own from amazon.com or shop.oreilly.com. I’ve seen O’Reilly.com offering discounts on a regular basis so keep checking. Alternatively attend one of my Java EE 7 hands-on lab at any conference and the first one to complete all the exercises gets a copy from me 😉

Now on my way to JFall, Transylvania JUG, and Devoxx!
