运行jdk1.8.0的ARM上的JavaFX

Question

I know that Oracle removed JavaFX in 8u33, but I'm wondering why I can't use JavaFX with jdk1.8.0? I got it from the Oracle archives ( http://download.oracle.com/otn/java/jdk/8-b132/jdk-8-linux-arm-vfp-hflt.tar.gz )

I have this extracted in /usr/bin/java_8_arm/jdk1.8.0 and am running my .jar file with sudo /usr/bin/java_8_arm/jdk1.8.0/bin/java -jar jarfile.jar

Running /usr/bin/java_8_arm/jdk1.8.0/bin/java -version returns

java version "1.8.0"
Java (TM) SE Runtime Environment (build 1.8.0-b132)
Java HotSpot (TM) client VM (build 25.0-b70, mixed mode)

and running System.out.println("Running Java version: " + Runtime.class.getPackage().getImplementationVersion());

returns Running Java Version: 1.8.0

The error I'm getting is:

Exception in thread "main" java.lang.NoClassDefFoundError: javafx/embed/swing/JFXPanel
    at front_end.GUI.initGUI(GUI.java:47)
    at back_end.Run.main(Run.java:28)

If you're wondering, I'm programming and compiling the program to a shared file via Windows 7 and running the JAR from a Raspberry Pi.

inb4 "why do you need javafx on a raspberry pi" - to render html, since other java components only support html 3.2. I have tried other renderers. This is the only one I could even get working right on my desktop, let alone the RPi.

Also, I am programming and compiling on 1.8.0 as well.

UPDATE:

As per José Pereda's answer, I have downloaded the JavaFX files and placed them in my original java install (I am now using /usr/bin/jdk8u6/ as my folder, and obviously jdk1.8.0_06 ).

Here is my install hierarchy, starting from the lib directory:

/usr/bin/jdk8u6/lib/:
arm ext             javafx.properties  jfxswt.jar  tools.jar
ct.sym  ir.idl              jconsole.jar       orb.idl
dt.jar  javafx.platform.properties  jexec          sa-jdi.jar

/usr/bin/jdk8u6/lib/arm:
jli          libgstreamer-lite.so        libjfxmedia.so
libdecora_sse.so     libjavafx_font_freetype.so  libjfxwebkit.so
libfxplugins.so      libjavafx_font_pango.so     libprism_common.so
libglass_monocle.so  libjavafx_font.so       libprism_es2_eglfb.so
libglass_monocle_x11.so  libjavafx_iio.so        libprism_es2_monocle.so
libglass.so      libjawt.so          libprism_sw.so

/usr/bin/jdk8u6/lib/arm/jli:
libjli.so

/usr/bin/jdk8u6/lib/ext:
jfxrt.jar

I still get the same error.

You can download an updated and upgraded version of JavaFX for ARM from here: JavaFX Embedded SDK

Once downloaded on your Raspberry Pi, you'll need to extract and copy the content into your JDK 1.8 (check this link for embedded).

You will be able to run the latest JavaFX version for ARM* on your Pi, including the WebView control.

Also, using the Gluon plugin for your IDE, you'll be able to deploy remotely the project on your Pi as well.

EDIT

*ARM: Note that JavaFX for ARM has never supported Swing. Other features like the WebView and Media weren't supported either, but recently these have been included in Gluon's build.
