Reza Rahman: Default CDI Enablement in Java EE 7
October 03, 2013 -
As you may already know, in Java EE 6, you needed to explicitly add a beans.xml file in your application archive in order for CDI scanning to work. Because DI is correctly considered such a pervasive concern, Java EE developers often found this requirement confusing... One of the most significant changes in CD 1.1/Java EE 7 is that by popular request, CDI is now enabled by default. This means that there's no need to explicitly add a beans.xml to enable DI any more. However...

Markus Eisele: Travel Report: JavaOne 2013 - Back To Glory
October 02, 2013 -
The content was amazing. So many great topics presented by gifted speakers. Packed sessions and a keynote which came back to Moscone for the first time in years. No-one could any longer assume that Oracle isn't listening. It simply takes some time to turn big things around. But it is possible. And the community is driving that change by being interested, committed and providing their criticism and ideas for improvements...

John K. Waters: What's Coming in Java 8: A 'Truly Revolutionary Upgrade' Featuring Lambda

The biggest change coming in Java 8 is Project Lambda (JSR 335), which supports programming in multicore environments by adding closures and related features to the language. Reinhold called it the single largest upgrade to the programming model, ever -- larger even than generics. "It's the first time since the beginning of Java that we've done a carefully coordinated co-evolution of the...

Adam Bien: JAVAONE SAN FRANCISCO 2013: FEEDBACK

This year JavaOne started like in the old years- in the Moscone Center. Sunday's keynote consisted of two parts: strategy and technology. The main message of the strategy part was "the same programming model with Java 8 everywhere". The technology part was interesting, relevant and entertaining. Either I was extremely fortunate, or the advisory board did a great job this year... All sessions...
