These days, we are starting a new project for realizing a Rich Internet Application (RIA). One of the first questions is: Which technologies and frameworks shall we use? The backend will be Java or another modern JVM language, as we are mainly experienced Java developer. In most use cases, we also prefer web frameworks, which allow to code mostly in Java, as many of us just have basic knowledge regarding HTML and JavaScript.
A decision has to be made for the upcoming project: Shall we use HTML5 or JavaFX 2 for realizing the web client? If you ask Google for “javafx or html5”, you do not find much information. In the majority of cases, you end up with a presentation hold at several IT conferences in 2011: “Moving to the Client: JavaFX and HTML5 Presentation”. Here is the Slideshare link (from JavaOne 2011): http://www.slideshare.net/steveonjava/moving-to-the-client-javafx-and-html5. Because this presentation does not help much, we took a look at pros and cons, which are listed below in this blog post.
But let’s start from the beginning…
There is no real definition for RIA. Therefore, here is my definition for this blog post:
“A Rich Internet Application provides a modern looking web application with animations, effects and multimedia features. The web application is hardly recognizable as web application. There is no classic HTML user interface with forms, drop down boxes or tables. Typical features of web browsers such as bookmarking or forwards / backwards navigation are usually missing / not required. It is client-centric, i.e. most of the user interface is loaded at the beginning to offer very good responsiveness. Sometimes (i.e. if you use a web framework instead of just HTML5), a plugin must be installed (e.g. Java Runtime Environment or Adobe Flash Player). Pokerstars (www.pokerstars.com) is a very good example for a RIA.”
Several alternatives are available in the JVM environment for realizing a RIA:
* GWT also has nice (experimental) HTML5 support for some features already: http://www.google.com/events/io/2011/sessions/gwt-html5-a-web-developers-dream.html => If Google continues adding support for HTML5 to GWT, this may be a good alternative in the next years, too – you develop only in Java, and you do NOT need a browser plugin because GWT generates plain HTML and JavaScript. However, there are also rumors that GWT is dying due to Google’s new language Dart. Google did not comment this yet, or release a roadmap for GWT.
So, the question is when to use JavaFX 2 instead of HTML5 for realizing a RIA (from the view of a Java developer)? If you do not know much about HTML5 or JavaFX, you should look at Wikipedia or google for other articles.
What is HTML5?
=> http://en.wikipedia.org/wiki/Html5
Important: HTML5 is HTML + CSS + JavaScript! It offers several next generation features for modern web development, such as Offline Storage or Application Cache.
What is JavaFX?
=> http://en.wikipedia.org/wiki/Javafx
Reminder: We are talking about JavaFX 2.0. The main difference to earlier versions is that JavaFX now offers a Java API instead of a new programming language (JavaFX Script). Thus, it is easy to learn for a Java developer.
Pros
Cons
Probably, there are many other pros and cons for HTML5. Though, the named ones should be sufficient for deciding when to use HTML5 or JavaFX.
Pros
Cons
HTML5 and JavaFX 2 are both awesome for realizing RIAs including media, charts, animation, etc. In the end, both have a different target audience:
Have fun realizing your RIA with HTML5 or JavaFX 2. By the way: We will probably choose JavaFX for our internal project because the required Java plugin is no show-stopper and most colleagues are Java developer.
If I missed any important pros or cons, or if you have any other feedback, please feel free to leave a comment…

Another alternative for RIA is JVx. Take a look. If you use JavaFx maybe JVx is an option too.
For data centric applications, you save development time and have results in minutes.
Check out http://www.vaadin.com. It is a Server-side Java web framework that offers a Java-only, component-oriented programming model which is very similar to Swing --> very intuitive for Java and even JavaFX developers. Other than GWT, it is a Server-side web framework.
Internally, Vaadin uses GWT for rendering the client side UI components. As long as you don't create your own widgets, you don't have to deal with GWT or HTML/CSS/JS directly.
The result from a Client perspective is a HTML5 web app that runs without a client side JRE, but created using a light-weight Java-only programming model, and run by a full server-side Web framework including server-side validations ... etc.
I introduced Vaadin in my current project for a company-internal tool, and everybody likes it a lot.
To be honest, there's not too much load on this application - not sure if it would scale up for applications with a high number of concurrent users. Also, there are no very detailed requirements on the UI for this tool other than it should be "good-looking", "modern" and "user-friendly".
Hey Arne,
nice to hear from you...
I know Vaadin, and I really like it. It's an awesome server-centric web framework. Though, in my opinion it is no competitor for a RIA. I added some detail to the definition of a RIA above, which I forgot, unfortunately: "It is client-centric, i.e. most of the user interface is loaded at the beginning to offer very good responsiveness."
I think Vaadin is an awesome alternative to JSF, Wicket, Tapestry, and other server-centric web frameworks.
Best regards,
Kai
Salutations from the other side,
Thanks for raising this important topic and all the pros and cons. I've been walking this same path and due to the painfully long time it has taken JavaFX to get its act together I finally started looking around at what the HTML5 phenomena is all about. I can hardly begin to share here what is going on out there in the HTML5 universe, it is literally exploding with abilities and tools.
My project and strategy is moving forward faster now using a hybrid app strategy for JavaFX, Android and iOS. All of them support Webkit based web views. HTML5 is better than FXML (the real deal) and CSS3 rocks and Javascript has become very powerful over the years. Also, I love the foundation of having true standards and not having my important software held hostage by any one proprietary technology.
In my new view hybrid apps are the new cross platform vehicle. Alas, JavaFX is stuck on the desktop. I really love this brave new world of HTML5 as I have been taking an honest open look at it. There are many excellent Javascript APIs, just one of them is D3.js which works with a DOM HTML5 and SVG scene graph. Not only does it do graphics that exceed JavaFX it also has the right idea which is expressed in its name which stands for data-driven-documents (or in other words, model driven scenegraphs built with worldwide standards). Once you see what you can do with the new HTML5 stack its unreasonable to just pin all your hopes on JavaFX.
The truth is out there, hope you find what your looking for!
Have a look at CaptainCasa http://captaincasa.com/ it's pure Java and easy to use. We use it for our enterprise application with GlassFish, Java EE6.
It has a huge amount of GUI Components.

hello there and thank you for your information – I have definitely picked up something new from right here.
Looking forward for such type of post. Good Going.

Hi,
I tried javaFX and develped few desktop application, really its awsome feature.
I am trying to develop a web application with the combination of spring, hybernate and jsp. I do no how to use javaFX in jsp OR Is there any other way to use javaFX in web application.
Please guide me.
Hi. Thank you for the great article. I am still learning about all of the different areas of Java including Swing / now JavaFX2.., so this was a great read about RIA's in either of the 2 choices you mentioned.
I just had a comment about this part of your post:
Development with HTML / JavaScript instead of Java => Main disadvantage for a Java developer!
I would wager to bet many Java Developers these days are already being asked to work in these environments where html and JavaScript are being used a lot.
Anyway thanks again!
if you consider that java 7 was recently a big security risc and (mabe the situtation will even get worse) I think the biggest risc/con for javaFX is that your enterprise client company
might decide to completely uninstall java. That's quite a con.
Anyway thank you for sharing your evaluation
(I'm in the currently same situation)

Your definition of "dead" is wrong. A framework is not dead when its development slows or halts. It is dead when clients can't run it. The best example is Win32 / MFC. How much development has it seen in the last decade? Yet it's still what all major Windows programs are built on. Flash (and even Silverlight) won't be dead until browsers stop running them, and that time is not on the horizon.
