I work for a company called Farata Systems. Laura is our office manager, and she doesn’t know Java. Everyone else does. We work in the enterprise RIA space using Adobe Flex as a main development tool for creating all these Web pages connecting to the server side applications written in Java.
In December of 2008, Sun Microsystems has released the first version of a language for developing UI for RIA. I’ve been watching the evolution of JavaFX from its announcement at JavaOne 2007 till its release, but wasn’t able to find any demos that would prove that this extension of Java platform can be considered as a candidate for boring needs of enterprise applications. Watching demos like a bunch of balls moving inside a glass didn’t look too convincing to me.
We decided to contribute to Java community and invest some time and resources to figure out what JavaFX 1.0 is capable of. Most of the Java developers know what Pet Store application is. For many years this reference implementation has been used by Sun Microsystems as a part of Java BluePrints program for Java EE platform.
The current version of this application is described in the article called “Introducing the Java Pet Store 2.0 Application” that’s available at http://java.sun.com/developer/technicalArticles/J2EE/petstore/.
We re-used the existing back end of the Pet store, but performed a little facelift by replacing the UI developed with AJAX/JSP/JavaServer Faces with JavaFX 1.0.
I was working on this project with our senior Java developer Alex Litskevich who’s done lots of digging and research trying to find the best solutions whenever we would run into limitations of JavaFX.
The goal of this introductory article is to demo the JavaFX Pet Store. You can watch a quick prerecorded demo at this URL .
In the future, I’ll deploy this application in one of our public servers and will review the code.
Last year, while attending a conference in India, I met an excellent Sun’s software engineer Greg Murray, one of the authors of the idea of Pet Store application. Greg, I hope you’ll like this version of your pet store.
Flex, JavaFX, Silverlight…
I’ll be honest with you, during development of this application in the back of my mind I’ve been constantly comparing the way things are done in JavaFX with how I’d do the same with Adobe Flex.
Simply put, today, Flex is a lot more productive than JavaFX. But let’s remember that we are comparing products of versions 3 vs. version 1. If you know how to develop Swing applications, you might want to continue doing this rather than manually creating JavaFX 1.0 wrappers for Java code as we did in our Pet Store.
The biggest issue is that JavaFX 1.0 doesn’t include any UI component library that a Web developer needs. I’m not talking about data grids or tree views. Even such simple things as a hyperlink component aren’t there. I can’t think of any other reason but a trivial lack of time and limited human resources allocated by Sun for development of this new UI set.
Hopefully, Sun will release a JavaFX 2.0 in foreseeable future with a full set of UI components, containers, navigators, and layouts. Just to draw an analogy, Microsoft has released absolutely naked Silverlight 1.0 in 2007, but full featured Silverlight 2.0 became available a year after.
The good news is that Java developers have already started building their own open source components for JavaFX. The name of this project is jfxtras .
On the other hand, I see some features available for JavaFX developers that are missing in Flex.
For example, ActionScript doesn’t support multi-threading. This is not an issue when it comes to communication with remote sites – all remote calls are asynchronous and use callbacks for server-to-client data flows. But if you’d need to write or use an existing Java library that performs some CPU-intensive calculations on the client, I’m sure Java will beat ActionScript. The syntax of both languages is pretty similar though (see http://flexblog.faratasystems.com/?p=115).
JavaFX supports eval() function that allows to compile and execute a piece of code on the fly. Flex doesn’t support this useful feature.
Two-way binding already exists in JavaFX but in Flex will get it only in version 4.
I’ve yet to see some benchmarks comparing Flex and JavaFX network protocol. The latter just offers XML and REST for data exchange between client and server. Of course, you can program Java sockets or wrap up an RMI client into JavaFX – would it be faster than ActionScript Real-Time Messaging Protocol? We don’t know. Or take HTTP tunneling between Java Applet and a server-side Java stream. Would it be faster than using AMF, an HTTP-based binary protocol? We don’t know yet.
JavaFX removes a lot of complications in developing mobile applications. It promises to remove the need of using Java SE for desktop and Java ME for mobile – JavaFX should be the only solution you need. JavaFX Mobile 1.0 offers hardware acceleration. Keep in mind, there are 2.6 billion of Java enabled mobile devices! JavaFX has serious advantage in this domain over Flash Lite.
JavaFX 1.1 has been released on February 12, 2009. It offers performance improvements, bug fixes, new features in the mobile space, but no major additions to the desktop platform.
I understand that this is not a good time to ask for some serious cash injections, but if executives of Sun Microsystems won’t find a way to double the size of the team working on the future version of JavaFX, entire Adobe Flex team can safely go on sabbatical for a year. If the money is tight, the sooner JavaFX will go open source, the better.
Even though I wouldn’t start developing with JavaFX a project that needs to go in production this year, overall, JavaFX looks promising. Try it out and see for yourself.

DevOps Summit 2015 New York, co-located with the 16th International Cloud Expo - to be held June 9-11, 2015, at the Javits Center in New York City, NY - announces that it is now accepting Keynote Proposals. The widespread success of cloud computing is driving the DevOps revolution in enterprise IT. Now as never before, development teams must communicate and collaborate in a dynamic, 24/7/365 environment. There is no time to wait for long development cycles that produce software that is obsolete at launch. DevOps may be disruptive, but it is essential.

The major cloud platforms defy a simple, side-by-side analysis. Each of the major IaaS public-cloud platforms offers their own unique strengths and functionality. Options for on-site private cloud are diverse as well, and must be designed and deployed while taking existing legacy architecture and infrastructure into account. Then the reality is that most enterprises are embarking on a hybrid cloud strategy and programs. In this Power Panel at 15th Cloud Expo (http://www.CloudComputingExpo.com), moderated by Ashar Baig, Research Director, Cloud, at Gigaom Research, Nate Gordon, Director of T...

Nigeria has the largest economy in Africa, at more than US$500 billion, and ranks 23rd in the world. A recent re-evaluation of Nigeria's true economic size doubled the previous estimate, and brought it well ahead of South Africa, which is a member (unlike Nigeria) of the G20 club for political as well as economic reasons. Nigeria's economy can be said to be quite diverse from one point of view, but heavily dependent on oil and gas at the same time. Oil and natural gas account for about 15% of Nigera's overall economy, but traditionally represent more than 90% of the country's exports and as...

The Internet of Things is a misnomer. That implies that everything is on the Internet, and that simply should not be - especially for things that are blurring the line between medical devices that stimulate like a pacemaker and quantified self-sensors like a pedometer or pulse tracker. The mesh of things that we manage must be segmented into zones of trust for sensing data, transmitting data, receiving command and control administrative changes, and peer-to-peer mesh messaging. In his session at @ThingsExpo, Ryan Bagnulo, Solution Architect / Software Engineer at SOA Software, focused on desi...

We certainly live in interesting technological times. And no more interesting than the current competing IoT standards for connectivity. Various standards bodies, approaches, and ecosystems are vying for mindshare and positioning for a competitive edge. It is clear that when the dust settles, we will have new protocols, evolved protocols, that will change the way we interact with devices and infrastructure. We will also have evolved web protocols, like HTTP/2, that will be changing the very core of our infrastructures. At the same time, we have old approaches made new again like micro-services...
