A new feature in JEE7 is Batch Processing, an implementation of JSR 352 based on the programming model of Spring Batch. With batch processing, we understand the execution of a series of jobs (steps) , sequential or in parallel, without any user interaction. In this blog, we want to give a small overview of the capabilities […]

Functional interface In many cases – when talking about Java 8 – lambda-functions are the first thing that comes up. I found it a concept hard to grasp, as it slightly changes the way you think about coding. In this blog, I would like to show you some very simple examples, and explain what is […]

A lot of new annotations have been introduced since the JEE6 spec. Before we had EJBs and servlets to cover most of our server-side objects in a JEE application. But in JEE6, CDI and JAX-RS have been added, along with a few other JSRs that are implemented using annotations. This results in a long list of annotations, where – in my opinion – it is not […]

Since Java SE 7, update 6 , JavaFX is part of the Java SE, it is officially replacing Swing as Oracle’s UI library for Java, and it runs on (any) desktop, mobile, and within the browser (applet). Java SE 7 includes version JavaFX 2.2, Java SE 8 includes JavaFX8, i.e. the version we will use here. In this […]

Default method’s  (aka Defender methods) in interfaces are new in Java 8. They enable you to define a default implementation of a method in the interface itself. If an interface is implemented by several classes, it’s hard to add method’s afterwards, as it will break the code and require all implementing classes to define the […]

Websockets (JSR 356) and the JSON-Processing API (JSR 353) are both introduced in the JEE7 specification. Together with JavaScript an HTML5, they enable web applications to deliver a richer user experience. Websockets allow you to communicate bidirectional and full duplex over TCP, between your server and different kind of clients (browser’s, JavaFX… ). It’s basically a […]
