If you were able to load and run JavaScript you probably did everything 
right.

However, if you just want to play with Nashorn the simpler option may be 
to use an official JDK preview release from 
http://jdk8.java.net/download.html. You can use the following command to 
just get the Nashhorn sources:

hg clone http://hg.openjdk.java.net/nashorn/jdk8/nashorn nashorn
