Cannot Upload code to Robot

com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "C:\Program Files\Java\jre1.8.0_65"

What does all this mean? I'm new to FRC programing and don't understand what the problem here is.
Thanks if anyone can help us out

It looks like you've installed, the JRE, not the JDK. Follow the instructions for installing Java on the ScreenSteps: http://wpilib.screenstepslive.com/s/...eclipse-c-java
