Oredev 2011 Trip Report




Oredev had its seventh annual conference in the city of Malmo, Sweden last week. The name "Oredev" signifies to the part that Malmo is connected with Copenhagen with Oresund bridge.

There were about 1000 attendees with several speakers from all over the world. The first two days were hands-on workshops and the next three days were sessions. There were different tracks such as Java, Windows 8, .NET, Smart Phones, Architecture, Collaboration, and Entrepreneurship. And then there was Xtra(ck) which had interesting sessions not directly related to technology.

I gave two slide-free talks in the Java track. The first one showed how to build an end-to-end Java EE 6 application using NetBeans and GlassFish. The complete instructions to build the application are explained in detail here. This 3-tier application used Java Persistence API, Enterprsie Java Beans, Servlet, Contexts and Dependency Injection, JavaServer Faces, and Java API for RESTful Services. The source code built during the application can be downloaded here (LINK TBD).

The second session, slide-free again, showed how to take a Java EE 6 application into production using GlassFish cluster. It explained:
  • Create a 2-instance GlassFish cluster
  • Front-end with a Web server and a load balancer
  • Demonstrate session replication and fail over
  • Monitor the application using JavaScript
The complete instructions for this session are available here.

Oredev has an interesting way of collecting attendee feedback. The attendees drop a green, yellow, or red card in a bucket as they walk out of the session. Not everybody votes but most do. Other than the instantaneous feedback provided on twitter, this mechanism provides a more coarse grained feedback loop as well. The first talk had about 67 attendees (with 23 green and 7 yellow) and the second one had 22 (11 green and 11 yellow).

The speakers' dinner is a good highlight of the conference. It is arranged in the historic city hall and the mayor welcomed all the speakers. As you can see in the pictures, it is a very royal building with lots of history behind it. Fortunately the dinner was a buffet with a much better variety unlike last year where only black soup and geese were served, which was quite cultural BTW ;-)






The sauna in 85F, skinny dipping in 35F ocean and alternating between them at Kallbadhus is always very Swedish. Also spent a short evening at a friend's house socializing with other speaker/attendees, drinking Glogg, and eating Pepperkakor.  The welcome packet at the hotel also included cinnamon rolls, recommended to drink with cold milk, for a little more taste of Swedish culture.

Something different at this conference was how artists from Image Think were visually capturing all the keynote speakers using images on whiteboards. Here are the images captured for Alexis Ohanian (Reddit co-founder and now running Hipmunk):





Unfortunately I could not spend much time engaging with other speakers or attendees because was busy preparing a new hands-on lab material. But was able to spend some time with Matthew Mccullough, Micahel Tiberg, Magnus Martensson, Mattias Karlsson, Corey Haines, Patrick Kua, Charles Nutter, Tushara, Pradeep, Shmuel, and several other folks.

Here are a few pictures captured from the event:

Thank you Matthias, Emily, and Kathy for putting up a great show and giving me an opportunity to speak at Oredev. I hope to be back next year with a more vibrant representation of Java - the language and the ecosystem!

Hi Arun

Thanks for posting the directions for your sessions! I am sure I am not the only one that will be going over them to learn to use the great features you demonstrated.

Regards

Mads
