DevNexus 2013 Trip Report
By reza_rahman on Feb 22, 2013
On the first day of the conference, I presented my session on Java EE titled "JavaEE.Next(): Java EE 7, 8, and Beyond". The talk is 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 was received well and I had some pretty good discussions during Q & A. It was a completely full house session with standing room only! The slides for the talk are here:
To my delight, the DevNexus folks were very interested in my NoSQL/Java EE talk (titled "Using NoSQL with JPA, EclipseLink and Java EE"). The talk covers an interesting gap that there is surpringly little material on out there. The talk has four parts -- a brief overview of JPA 2.1, a birds-eye view of the NoSQL landscape, how to use NoSQL via a JPA facade using EclipseLink NoSQL, Hibernate OGM, DataNucleus, Kundera, Easy-Cassandra, etc and how to use NoSQL native APIs in Java EE via CDI. This talk was also a full house, the Q & A was excellent and I got great feedback afterwards. The slides for the talk are here:
The first demo used MongoDB, JPA, EclipseLink NoSQL and JUnit. The code for it is available on this GitHub repository: https://github.com/m-reza-rahman/jpa-nosql-demo. The second demo used MongoDB, CDI, Arquillian and JUnit. The code for it is available on this GitHub repository: https://github.com/m-reza-rahman/cdi-nosql-demo. Give me a shout if you need help getting the demos up and running. I plan to write a two-part blog using the contents of this talk, so stay tuned.
