I have installed JavaFX SDK on my machine, and set the JAVAFX_HOME environmental variable to the root directory of the SDK but when I try to echo it on the commandline, I only get back what I wrote after echo:
I acted the same with JAVA_HOME but it works properly.
At first, set the environment variable as
C:\Program Files\Oracle\JavaFX 2.1 SDK.
and try echo
%JAVAFX_HOME%. It'll work.
