RE: Pete's web5250 was->Re: Business Developers was ->Re: IBM Gives RPG Devotees Their Own Café




:)

I suspect JavaFX to be quite popular in some time. For Java programmers it's a no-brainer to use FX to build nice looking desktop apps. As a RIA platform, the fact that it is an extension of the Java platform (JFX is compiled to normal Java classes), in combination with the ease of building a slick UI, and Java being open source, and having the Java platform at your disposal (you can mix your JFX code with - your own - Java classes) makes for a huge potential. Also Sun works hard to make the JVM more agile, breaking it up into different pieces to reduce start-up time and resources.

Imagine how users will react if you put a thin JFX interface onto your "i" apps....

Hi John.

I had never heard about JavaFX - but after browsing around, download it to
my NetBeans .. must say .. I'm in love :)

The language is a crossover between java and javascript. Fx is a dynamic
language where you access java classes and define object just like in
javascript. Very slick way of inherence and the way to expose methods as
properties with a simple "bind" keyword - is just brilliant.

JavaFX is actually another good argument for making the 5250 javascript
proxy - JavaFX will just swallow the JSON stream I am talking about....

Answer 1:
JavaFX is a layer upon the normal JVM. In fact, it *is* simply Java, but
with a new nice declarative language with which it is far easier to build
attractive UI's as with Swing. But it's simply Java. For some that seems to
be a problem, for others its a big advantage.
So JavaFX is delivered through the normal JVM plugin, which is Java 6 update
10 (or 11 now). The start-up time seems to be reduced, and you can even drag
an applet to the desktop so it runs outside the browser (dont need the
browser anymore the start the app).
For public apps, depending on the app and the customer, HTML/Javascript
maybe a better option. Because it's ubiqious.
JavaFX 1.0 has now one week or so old, so don't judge it now, but keep your
eyes on it. The big advantage of JavaFX is that it is based on the stable,
robust and efficient Java platform. IMO, it has big potential. To contrast
it with Flex, the latter is more for apps where design and looks is more
important than functionality. You can't build a complex app in Flex (flash)
without running into all kinds of problems, like memory leaks and
performance problems. It is no basis for business application development,
but more for ads and the like.

Answer 2:
JavaFX is rather new, but if you google then there are enough example apps
you can try.
I googled one up for you: http://javafx.com/samples/

<Ignorance warning>

How is JavaFX originally delivered to the users desktop? Is it similar
to a "browser add-on" like Flash or Silverlight, or is it more like
downloading the .NET framework (guessing the latter). If that's the
case then I can see it working for internal apps, but that still leaves
the need to do public web sites where the viability of your business can
depend on how easy/non-intrusive it is to use your website - hence why
HTML+CSS+JavaScript will seemingly forever be trying to mirror what
other "thicker" technologies can do better.

Question 2: Do you know of any current online sites that use JavaFX?
Everytime I see an update about the technology I always try to take the
time to read it, but I don't believe I have ever actually seen a JavaFX
app. Do you know of any by chance?

Thanks,

JavaFX to be precise which is quite efficient and can provide a very
aesthetic look. Its better suited for business apps (e.g. it can be made
keyboard centric much easily as html/javascript) *and* you have the
availability of the vast java platform libraries on the client, *and* you
have far less security problems. For example it would be possible to access
the local disk in a controlled way.

As others (well, at least one other person) already stated, the browser
is a dead end for serious (business) apps, IMHO.
