Three Steps to Build a Killer WebSocket App with JavaFX

The app I wanted to build consumes the same data source as the lightning fast Kaazing portfolio demo

As part of my prep for the talk we give at JavaOne 2012, I built a WebSocket app using JavaFX 2.2 front-end with NetBeans 7.2 and the brand new JavaFX Scene Builder 1.0.

The tools were a pleasant surprise, they were pretty straight-forward to use. Most of the Oracle tutorials were helpful too, although I couldn’t find signs of an active and extensive JavaFX developer community out there.

The app I wanted to build consumes the same data source as the lightning fast Kaazing portfolio demo.

This video demonstrates what it looks like in the development environment, as well as running, side-by-side with the aforementioned JavaScript implementation of the Kaazing portfolio demo.

Step 1 – Creating a JavaFX App

First, I created a new project: JavaFX > JavaFX FXML Application.

Step 2 – Defining the UI

Then, using the new JavaFX Scene Builder, I created the grid layout I wanted to render. The JavaFX Scene Builder can be invoked by double-clicking on your fxml file in NetBeans. If you want to edit the XML in NetBeans directly, there’s a context menu that allows you to do so.


On the next page you'll find the source for my Sample.fxml file.
