JDK.IO 2014 was held in Denmark on January 19-20 at the IT University of Copenhagen. It is the yearly conference of 'JavaGruppen', the Danish JUG. The conference sessions covered a variety of Java topics ranging from core Java, Java EE, and JavaFX. Speakers included my colleague David Delabassee, Simon Ritter, Adam Bien, Heinz M. Kabutz, Bert Ertman, Ryan Cuprak, Simon Maple and Markus Eisele.
David covered the Java EE portion of the keynote. He also presented a talk on Java EE 8. His slides from SlideShare are embedded below:
My friend, fellow co-author of EJB 3 in Action, Connecticut JUG leader and JavaOne Rock Star Ryan Cuprak presented a couple of very cool sessions. The first one, titled Hybrid Mobile Development with Apache Cordova and Java EE 7 demonstrates how Java EE can be used as a very effective mobile development back-end using APIs like JAX-RS, WebSocket and JSON-P. The talk was delivered at JavaOne 2014 as a tutorial and includes an excellent end-to-end demo. Video from the JavaOne talk is embedded below:
Ryan also presented another popular talk from JavaOne 2014 - 50 EJB 3 Best Practices in 50 Minutes. At JavaOne he had co-presented the talk with my other co-author Michael Remijan. The video from that talk is embedded below:
Ryan wrote up a very nice trip report of JDK.IO on his personal blog that you should check out. Other Java EE related talks included one by Markus Eisele on Java EE 7 and Apache Camel.
