Kaazing’s own Marcelo Jabali posted a nice write-up on accessing a MySQL database directly from the browser using WebSockets. Marcelo describes the building blocks and the config changes he had to make. Sample code is coming soon too. ... (more)

AJAX and Mozilla XUL with JavaServer Faces

In our previous JDJ article - Rich Internet Components with JavaServer Faces - we discussed how JavaServer Faces can fulfill new presentation requirements without sacrificing application developer productivity building Rich Internet Applications (RIA). We discussed how JSF component writers can utilize technologies, such as AJAX and Mozilla XUL, to provide application developers with rich, interactive and reusable components. In order to use AJAX and Mozilla XUL with JSF, component writers have to make sure to provide any resource files need by these technologies, such as images... (more)

Three Steps to Build a Killer WebSocket App with JavaFX

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...

Real-Time Tic Tac Toe Light

I had the great privilege of being a speaker at HTML5 Developer Conference in San Francisco recently.  It was the second HTML5 Dev Conf I have presented at, with the first one being October 2013.  This time, I paired with Frank Greco to present a session entitled “WebSockets: Past, Present and Future”.  Frank took the stage for the first half of the session, and I followed up with some hands-on Internet of Things (IoT) demonstrations that were integrated with Kaazing Gateway. Introducing the Tic Tac Toe Light My personal favorite demonstration was a project I called the “Tic Tac ... (more)

Super-Charge JSF AJAX Data Fetch

In our last article - "JSF and AJAX" (JDJ, Vol. 11, issue 1) - we discussed how JavaServer Faces component writers can take advantage of the new Weblets Open Source project (http://weblets.dev.java.net) to serve resources such as JavaScript libraries, icons, and CSS files directly from a Java Archive (JAR) without impacting the application developer. In this article we'll address the need to fetch data using AJAX with JavaServer Faces (JSF) components. The most common use cases for fetching data with AJAX are to populate dropdown lists and add type-ahead functionality in text fi... (more)
