Hi, Ken,

You can use JavaFx by 2 means.

A - Include the jars in the Java Build Path.  I've not been successful with this one, so, let me give you the second means.

B - Install the JavaFx plug-in for eclipse.  These are my notes as I worked through it.  Let me know if anything doesn't make sense.

  1. With Eclipse open, click Help > Install New Software…
  2. Click the Add… button.
  3. Enter a name, such as JavaFX.
  4. Enter the location as follows:  http://download.eclipse.org/efxclipse/updates-released/1.2.0/site/
  5. Check both options “e(fx)clipse – install” and “e(fx)clipse – single components” as shown.  Accept other defaults.  Click the Next button.
  6. These are the items that will be installed.  Click Next again.
  7. Accept terms and click Finish.

You’ll be prompted to reboot Eclipse.  The plug-in is now installed and is ready to use.

Now, to use JavaFx...

  1. Navigate to File > New > Project
  2. In the New Project wizard, select JavaFx > JavaFX Project
  3. Enter a name for the project, ie, JavaFxDemo, etc.  Click Finish.
  4. Go to the project name > src > application.  Click once on application to highlight.  Create classes here (right-mouse click, New > Class)

Hope this helps,

Holly
