None of the nasty things that you have said or implied about me are at 
all true.

P.S. What's with this thread necromancy tactic of yours? You did that 
during the Great SWT Flamewar too, as I recall -- sometimes you'd just 
dredge up a thread that had been inactive for weeks and post random new 
flame-responses into it. If it's supposed to be some sort of diversionary 
tactic to induce me to miss noticing something else in some other thread, 
though, it's doomed to failure, just like any other attack upon me.

RIA without context can mean many things.

But a reference in a comp.lang.java.programmer thread about
JavaFX do provide context.

RIA JavaFX
RIA java
RIA programmer

all find the right RIA.

There are several such articles.

And mostly I agree with them.

But you should realize what they are really saying.

They are not saying that "Swing were doing great for
Java applets and Java desktop apps, but now the change
from Swing to JavaFX will make it go bad".

They are saying that "Swing was doing poorly because
neither Java applets nor Java desktop apps were popular
and the change from Swing to JavaFX will not change that".

>    Could it be that JavaFX will be damaging Java?

Java applets and Java desktop apps has been a very very
small part of Java world (maybe 1-2%) and the fact that
JavaFX will do as poorly as Swing when it comes to market
share will not have any impact on the success of Java.

The "New thing"? Really???

JavaFX was still-born at least 5 years ago. HTML5, CSS3, and Javascript 
is the GUI. Applets OTOH provided real infrastructure on the client, 
without touching the GUI, that still enhanced the user experience with 
functionality that is not available (easily) elsewhere. (Eg: single 
sign-on, connection-oriented server communication)

Java IS the new COBOL! Serving up RESTful JSON is the best you can hope 
for from now on.

I am confused by this.  Perhaps it's the terminology.  You say it won't "compile" and applet, but it will "translate" an applet.

When I said compile, I meant compile where the target "machine code" was javascript.   That's the same a translate, right?

What I want to know is that if I go to the trouble of climbing the GWT learning curve, will I just have to issue a command and end up with some javascript that will do what the applet does without needing the java plugin.

Or, will I have to re-code a lot of the java code even if I am using the GWT?

Yes.

GWT does compile/translate to JavaScript.

But it does not compile/translate applets.

It compiles/translates Java code written in its own GUI framework.

Users will not need Java installed.

The code will need to be rewritten. But I think you will find all the 
concepts very familiar!

Let me post a small example:

package test.client;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.event.dom.client.ClickEvent;
import com.google.gwt.event.dom.client.ClickHandler;
import com.google.gwt.user.client.ui.Button;
import com.google.gwt.user.client.ui.FlowPanel;
import com.google.gwt.user.client.ui.Grid;
import com.google.gwt.user.client.ui.InlineLabel;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.user.client.ui.ScrollPanel;
import com.google.gwt.user.client.ui.TabPanel;
import com.google.gwt.user.client.ui.RichTextArea;
import com.google.gwt.user.client.ui.TextBox;

public class Page implements EntryPoint {
	public void onModuleLoad() {
		final TextBox tb1 = new TextBox();
		final TextBox tb2 = new TextBox();
		final TextBox tb3 = new TextBox();
		final Button addbtn = new Button("Add");
         addbtn.addClickHandler(new ClickHandler() {
         	public void onClick(ClickEvent event) {
         		int v1 = Integer.parseInt(tb1.getText());
         		int v2 = Integer.parseInt(tb2.getText());
         		int v3 = v1 + v2;
         		tb3.setText(Integer.toString(v3));
         	}
         });
         final Grid addgrd = new Grid(4, 2);
         addgrd.setWidget(0, 0, new InlineLabel("First number: "));
		addgrd.setWidget(0, 1, tb1);
         addgrd.setWidget(1, 0, new InlineLabel("Second number: "));
		addgrd.setWidget(1, 1, tb2);
         addgrd.setWidget(2, 0, new InlineLabel("Result number: "));
		addgrd.setWidget(2, 1, tb3);
		addgrd.setWidget(3, 0, addbtn);
		final RichTextArea rta = new RichTextArea();
		final Button bldbtn = new Button("B");
		bldbtn.addClickHandler(new ClickHandler() {
         	public void onClick(ClickEvent event) {
         	    rta.getFormatter().toggleBold();
         	}
         });
		final Button itbtn = new Button("I");
		itbtn.addClickHandler(new ClickHandler() {
         	public void onClick(ClickEvent event) {
         	    rta.getFormatter().toggleItalic();
         	}
         });
		final FlowPanel flowp = new FlowPanel();
		flowp.add(new ScrollPanel(rta));
         flowp.add(bldbtn);
         flowp.add(itbtn);
		final TabPanel tabp = new TabPanel();
		tabp.add(addgrd, "Add");
		tabp.add(flowp, "Edit");
		tabp.selectTab(0);
		RootPanel.get("content").add(tabp);
	}
}

Conceptually that is very close to a Swing app.

Thanks! I think I finally get the idea.

I'd have import gwt packages.

I guess I might have to change some methods for the GUI.

(Some of the GUI uses an early deprecated Java event model.)

I also use string and math packages in the applet.  Not much else.
I don't use cookies, files, communications

Looks similar to porting code from one operating system to another.

I have not written Java in a while.  I learned Java before 2000 and passed the Java certification test and taught an intro course a while as a community college and created poologic.com. But I have not had to done much maintenance on my website since around 2000.

I learned Java and C++ as backup to my legacy skills in case I had to find a new  job, but I never had to change jobs,  my day job is still maintaining legacy systems.

Arne,

I just got my core logic class working.  It require few modification, the java code required none.  I did not put many hours in, I am just working on for short periods.

The UI is going to take more work since the classes are not exactly the same.

Thanks again!

Do I have to do a partial rewrite?

If GWT translates an applet, why do I have to hand-translate the applet?

I could set down and hand-translate it myself to javascript with pretty much the same look and feel and the same functionality.  Does GWT not do that?  Does it do a partial job?

Somewhere around 2001-2002 I used to employ an Applet as a JS/Servlet 
communication broker for an in-house Ajax-avant-la-lettre framework. 
Even then it was clear that Applets had no future and I switched to a 
pure JS solution as soon as XMLHttpRequest became a viable alternative.

It is hard for me to understand why anyone would have invested in them 
over the last ten years or even just neglected to replace them.

If you are just maintaining/updating some stuff 3 could be a good 
approach but I have little experience there. If you have any future 
ambitions with this then 2 is the only sensible option.

I am not saying you have to manually do things in JS though. In many 
situations a server-centric Ajax approach will work fine allowing you to 
do (almost) everything server side (Java). But sometimes you need to go 
all client-centric which basically condemns you to death-by-JS :)

Bullocks indeed! We all know you intend to perpetually keep kicking the 
dead horse and are at the same time unable to take part in any 
intelligible and open minded discussion about this subject.

Nobody is saying that it is not very (technically) convenient for the 
software developer to have a complete Java stack available inside the 
users browser. It's just not going to happen anymore with the world 
moving to tablets, smart-phones and ultimately the IoT.

Everybody saw this coming long ago apart from some pigheaded idiots who 
decided to go down kicking and screaming like spoiled brats who's 
precious toys are taken away.
