should run on all the Java platforms with the javafx "compiler" package
No, it should compile on computers with teh javafx compiler. To run it, you just need a jre.

It is not just another dynamic scripting language suitable for text processing. Instead of comparing JavaFX to JavaScript or Groovy, it is more similar to Adobe Flash or Microsoft Silverlight.

JavaFX is aimed to be widely used to create animated rich Internet applications, especially for mobile devices. It may well become important technology considering the importance of mobile market, rich internet applications and the need for open alternatives.

Hi,

but in the tutorials I've seen they not only create the gui. They also use JavaFX for some logic behind the GUI.

But nevertheless: It looks strange Don't know the competitors (Flash, Silverlight), maybe they are even more ugly

Well Silverlight uses .Net so I'm guessing that they would use whatever language is supported in .net. I think python is one of those languages. If that is true then that is a huge win right their because the language is fairly powerful and established. I personally like javafx better at the moment if only because it's the only real open alternative at the moment. If Sun releases it to the public then some hackers could fix the issues with the language.

Adobes Flex is open source, or on it's way to being open source and the SDK is free for download now.

It runs on Flash 9 plugins and uses Active script for logic, which at quick glance reminds me of java a lot.

"I think python is one of those languages. If that is true then that is a huge win right their because the language is fairly powerful and established."

What makes you think Python would make a good language for developing multimedia application? Being established and powerful doesn't mean it is the right tool for the job.

I am primarily a Java developer and do quite a bit of Flash (ActionScript) development on the side. I have not looked at JavaFX yet, but I will be honest with you I'm skeptical. Plus you can't rely on a functional JRE on the client workstation. Until they prove they can make the JRE as ambiguous as the flash player JavaFX is going nowhere.

The tragedy for Sun is that JavaScript was never designed to be compatible with the Java framework or virtual machine, which are Sun's greatest development assets. Microsoft and Adobe designed their .NET and Flex frameworks to be compatible with ECMAScript, which is poised to become the dominant Web-2.0 virtual machine.

The upcoming ECMAScript v4 virtual machine specification will support dynamic or static object-oriented languages like IronPython or Boo, whereas the previous spec only supported prototype-oriented languages like JavaScript. Mozilla is definitely going this direction, although WebKit has yet to confirm its intentions.

So while Microsoft and Adobe are embracing JavaScript, the dominant client-side scripting language, and a whole host of higher-level scripting languages, JavaScript has no future in Sun's Web-2.0 stack. They need a scripting language based on Java and the JVM, plus a markup language. Instead of using Groovy or Jython and creating a separate markup language like XAML and MXML, Sun developed a declarative scripting language that integrates the markup component.

This is a horrible idea because it doesn't allow developers to leverage their existing language skills on Sun's JavaFX stack. The whole framework is bound to JavaFX Script, a brand-new and somewhat unusual language. Furthermore, it uses a heavier runtime that isn't going to be the default in the next-generation rendering engines.

JavaScript, not Java, turned out to be the killer app for the web. How could Sun NOT have seen that coming?

Er, what about Rhino - Mozilla's JS engine written in pure Java: http://www.mozilla.org/rhino/

I think Rhino is going to be replaced by Tamarin, the ECMAScript v4 engine contributed by Adobe. This forms the backbone of Mozilla 2, upon which Firefox 4 will be based.

But, yes, Sun could have used something like Rhino if they wanted to support JavaScript and other ECMAScript languages in JavaFX.

Hi, very interesting post!

But in JavaFX it is possible to use everything of Java or not? So it should be possible to write some backend code with the language Java and call it from the JavaFX-based gui. Or isn't this possible?

Unless its quality is 0. And also I'd say it's not the price that matters, but cost. So not that simple, really.

i think that if you look up the best software in the various fields, the majority would be free..

also, you seem to have your prioities mixed up..

imagine a country where you have everything, except for 1 thing, freedom, could that ever really be the best, even though you have a thousand other "benefits" over the other democratic country which pays more in tax for less service?

Hi,

well there are some things that are really cool in JavaFX: The model bindings and triggers.

In swing those things aren't possible at the moment in that easy way.

What I don't understand, here a small example:


class Model {
attribute tabPlacement: TabPlacement;
attribute tabLayout: TabLayout;
attribute tabCount: Integer;
attribute selectedTab: Integer;
}

var model = Model {
tabPlacement: TOP
tabLayout: WRAP
selectedTab: 3
tabCount: 5
};

Frame {
height: 300
width: 400
content: TabbedPane {
tabPlacement: bind model.tabPlacement
tabLayout: bind model.tabLayout
tabs: bind foreach (i in [1..model.tabCount])....
}


Is it possible to write this class "Model" with Java? The GUI gets connected to the Class, the logic of the program. So for me it is important to use already existing classes here. I don't want to write whole programs with JavaFX

Greetings

Mike
