Cannot run FX applets in Java 7 and 8 install and Java 8 is disabled via JCP.
Follow steps from https://bugs.openjdk.java.net/browse/JDK-8028644.
1) Install JRE 8u5
2) Install JRE 7u55
3) Disable JRE 8u5 via JCP on Java tab.
4) Run http://download.oracle.com/otndocs/products/javafx/2/samples/Ensemble/index.html
Note: I tried several more FX applets and non of then works.
Browser will give error:
JavaFX application could not launch due to system configuration (show error details). See java.com/javafx for troubleshooting information.
Reproducible on Windows 7 with IE, Firefox and Chrome. Did not tried on other platforms.
Java.com and AWT applets seems to work fine in this configuration.
