# As Nashorn does not have http capabilities through XMLHttpRequest (DOM API), we have to use regular Java classes instead.
# This sample shows how this can be acheived without depending on any third party libraries. Just a standard Java 8 JDK.
# Make sure to have JAVA_HOME/bin on your PATH for the shebang to work. Then just chmod +x away and run...
# Alternatively if you're on a non *nix OS, start with jjs -scritping httpsample.js
