In this video interview, senior architects Andres Almiray and Swen Reimers discussed hackagarten event taking place during the conferences. "A hackergarten is group of people coming together for a couple of hours. We decide the open source projects we want to code on. It can be fixing a bug, adding a new feature, creating a screencast, testing features and giving feedback to the project. The goal is to contribute to an open source project" explained Andres.
Devoxx Hackergarten focused on Java EE Lambda projects this year. Swen was the project lead and mentor for the Lambda projects. Some of them worked on JavaFX and Lambda event threads. "We discussed why things would not fit in an API, the lambda syntax, and what is available or not" Swen mentioned. They are running hackergarten around the world. The next ones will be at JFokus, JavaLand and the monthly events in Basel, Switzerland.

Up on otn/java is a new article by Oracle senior software engineer Mahesh Kannan, titled “An Overview of Batch Processing in Java EE 7.0,” which explains the new batch processing capabilities provided by JSR 352 in Java EE 7. Kannan explains that “Batch processing is used in many industries for tasks ranging from payroll processing; statement generation; end-of-day jobs such as interest calculation and ETL (extract, load, and transform) in a data warehouse; and many more. Typically, batch processing is bulk-oriented, non-interactive, and long running—and might be data- or computation-intensive. Batch jobs can be run on schedule or initiated on demand. Also, since batch jobs are typically long-running jobs, check-pointing and restarting are common features found in batch jobs.”
JSR 352 defines the programming model for batch applications plus a runtime to run and manage batch jobs. The article covers feature highlights, selected APIs, the structure of Job Scheduling Language, and explains some of the key functions of JSR 352 using a simple payroll processing application. The article also describes how developers can run batch applications using GlassFish Server Open Source Edition 4.0.
Kannan summarizes the article as follows:
“In this article, we saw how to write, package, and run simple batch applications that use chunk-style steps. We also saw how the checkpoint feature of the batch runtime allows for the easy restart of failed batch jobs. Yet, we have barely scratched the surface of JSR 352. With the full set of Java EE components and features at your disposal, including servlets, EJB beans, CDI beans, EJB automatic timers, and so on, feature-rich batch applications can be written fairly easily.”

Oracle has started to open source JavaFX, the rich client platform for Java applications. The list of open sourced projects will be growing in the next couple of weeks with an additional 7 projects. "We are also going to open source our iOS and Android implementations over the next couple of months" announced Richard Bair, architect of the JavaFX platform, in his blog.
