33rd Degree 2013 Trip Report

33rd Degree 2013 was held in historic Warsaw, Poland on March 13-15. For those of you not familiar with it, dubbed "the Conference for Java Masters" this is the premier Java conference for Poland. It attempts to bring together elite speakers in the Java community across the globe. This was my first time at the conference and I most certainly thought the conference lived up to its promise. Just some notable speakers included Tim Berglund, Adam Bien, Ted Neward, Dan North, Simon Ritter, Venkat Subramaniam, Geertjan Wielenga and Kai Wahner.

I delivered three full-house talks, all on the second day of the conference. The first was my talk on Java EE 7 and 8 titled "JavaEE.Next(): Java EE 7, 8, and Beyond". The talk was primarily along the same lines as Arun Gupta's JavaOne 2012 technical keynote. I covered the changes in JMS 2, the Java API for WebSocket (JSR 356), the Java API for JSON Processing (JSON-P), JAX-RS 2, JPA 2.1, JTA 1.2, JSF 2.2, Java Batch, Bean Validation 1.1, Java EE Concurrency and the rest of the APIs in Java EE 7. I also briefly talked about the possible contents of Java EE 8. The talk had standing room only with 400+ attendees. The slides for the talk are here:

My second talk was on the Java API for WebSocket/JSR 356 titled "Building HTML5/WebSocket Applications with JSR 356 and GlassFish". The talk is based on Danny Coward's JavaOne 2012 talk. The talk covers the basic of WebSocket, the JSR 356 API and a simple demo using Tyrus/GlassFish. The talk went very well and there were some very good questions. This was a full session as well with 150+ attendees. The slides for the talk are here:

The code samples are available here: https://blogs.oracle.com/arungupta/resource/totd183-HelloWebSocket.zip. Give me a shout if you need help getting it up and running.

To my delight, the 33rd Degree folks were very interested in my domain-driven design/Java EE talk (titled "Applied Domain-Driven Design BluePrints for Java EE"). The talk has three parts -- a brief overview of DDD theory, mapping DDD to Java EE and actual running DDD code in Java EE/GlassFish. I converted the well-known DDD sample application (http://dddsample.sourceforge.net/) written mostly in Spring 2 and Hibernate 2 to Java EE 7. My eventual plan is to make the code available via a top level java.net project. Even despite the broad topic and time constraints, the talk went very well. The room was fully packed with 400+ people and I got excellent feedback on the talk later. The slides for the talk are here:

The code examples are available here: https://blogs.oracle.com/reza/resource/cargo-tracker.zip for now, as a simple zip file. Give me a shout if you would like to get it up and running.

Besides presenting my talks, I got to attend some great sessions on Java SE, JavaScript/HTML5, NoSQL and mobile. It was also good to catch up personally with Adam, Kai, Simon and Geertjan.

On a more personal note, I was very curious to explore the heavy metal scene in Poland because I know there have been many brilliant but seriously underrated Polish metal bands like Vader and Behemoth. Luckily for me, bitter cold Winter Friday nights are metal nights in Warsaw. I got to check out some of the city's best young metal bands at the storied Metal Cave.

I definitely enjoyed 33rd Degree 2013 and hope to be part of the conference again next year.
