TwitterPizza, DukeMugs and eTradr - Three Java EE 6 Sold Out Hacks

One week with three slide-less sold out Java EE 6 events. The week started with JUG Berlin. Attendees decided for the Pizza Service implemented with Java EE 6 - so we did it. A student even managed to implement the application with me in real time. There were about 100 free places - the event was sold out in 3h.

In about 1 hour at the Java Dev Day we built DukeMugs Java EE 6 application. Oracle sponsored ten mugs with duke rockstar, which I gave away for the best questions. This event was moved from a smaller into a bigger room. We reached the max capacity of the bigger room as well, so the registration had to be closed...

In a whole day workshop at OOP Conference in Munich, we built an eTradr application. An attendee had deep trading domain knowledge, so we leveraged that for building a application and explaining Java EE 6 practices and techniques. We managed to build a whole application with Unit tests, mocking, load tests, REST (json, persistence), transactions, Servlets 3, JSF 2, discussing modules, architectures etc. I answered approx. >50 questions during the workshop and during the break.

The room was big enough, but they were not enough chairs... It was fixed before the event.

I pushed all sample apps into (in the "hacks" folder). The "patterns" and best practices are also described in my latest book.

Seems like Java EE 6 becomes extremely popular - at least all Java EE 6 related events are consistently sold out. Also interesting: only few attendees are actively using J2EE 1.4, the majority uses Java EE 5 and only few are using Java EE 6. Good news: the migration from Java EE 5 to Java EE 6 is nothing but fun :-)

NEW: Online Workhop Effective WebApps without Frameworks is also coming to: MUC Airport.

Airport MUC workshops: Web (SPA, PWAs, Offline, Desktop, Mobile) Applications Essentials and Effective Web Applications. No migrations. #usetheplatform

Podcast: and newsletter:

A book about rethinking Java EE Patterns


Many thanks for your presentation and the provided source code! As you wrote that there will be free beer and pizza at the JUG Berlin, I thought that it is fun. But at the end I have gone home with three pizza boxes. *g*

Greetings to wherever you are currently,

The student who managed to implement the application in real time with you ;)

yes - you really surprised me showing me a working application in the Pizza / Beer break. Have fun with Java EE 6!,
