Setting The Classpath For Nashorn Script in jjs / Java 8

The Java 8 jjs interpreter accepts the -cp / -classpath argument. After setting the classpath, all the classes become available from within the executable script.

A utility class com.airhacks.naslib.Inspector in the naslib.jar (this is an sample jar) becomes available for Nashorn after setting the jjs classpath:

#!/usr/bin/jjs -cp ./naslib/target/naslib.jar -fv
//built-in variable
var args = $ARG;

var Inspector = com.airhacks.naslib.Inspector;
//class from jar, calling a static method

In case this post looks a bit crazy to you, you would enjoy the Java 8 / Java EE 7 "More Power with Less Code" workshop :-).


Hi Adam,
Have you tried it on Linux? It seems that the complite shebang options are interpreted as one option.

The syntax you used does not work for me on Linux. Try this instead:

#!/usr/bin/jjs -Dnashorn.args=-cp ./naslib/target/naslib.jar -fv
