What moved the Java world in Poland ? About 600 participants, 60+ sessions, 45+ speakers, and 3 days at Geecon!
This was my first time at the conference and they kept me busy :-) I've delivered the self-paced Java EE 6 hands-on lab multiple times all around the world, but this is the first time where I used the content to demonstrate the simplicity and ease-of-use of the platform in a code-driven session. The 2 hrs were entertaining with constant interaction from about 50+ attendees. The lab material can be downloaded from here anyway.
Then right after I gave a talk on Java EE 7: Developing for the Cloud. This talk gave an introduction to the upcoming Java EE 7 platform to about 50 attendees. And I refreshed the slide deck with tons of code samples from different technologies such as JAX-RS 2.0, JPA 2.1, and Bean Validation 1.1 that have released their early drafts so far. The slide deck is available.
Pete Muir also helped me provide a more thorough insight into Contexts & Dependency Injection 1.1.
The talk on JAX-RS 2.0 had about 100+ attendees where I gave an introduction to JAX-RS, explained the motivation behind upcoming features, and showed code samples of how the API is evolving. The slide deck is available here.
And finally the last talk shared our experience of building a PaaS platform using GlassFish, the slides are available.
This talk explained the internals of GlassFish and how Orachestration Engine, Service Provisioning Engine, IaaS Management Service, and Cloud Elasticity Manager work together to provide a Java EE 7-based PaaS environment.
Overall, the movie theater-style seating worked well and the technical crew knew their job very well. The volunteers were very prompt in showing the time remaining which was helpful. Everybody in the conference team gave a very welcome feeling which certainly wants me to go back there again next year (provided they accept my submissions ;-) Thank you AdamD (Poznan JUG leader and conference organizer), AdamP, Adrian, Marcin, Lukasz, and everybody else for a great show!
The speakers' dinner was in the old part of the town and I enjoyed sharing stories with Gavin King, Pete Muir, Stephane Eperdaud, Anton Arhipov, Joonas Lehtinen, and many others.
Here are some pictures captured from the trip ...
