importing js module in JS script

Question

How to import resemblejs module in my JS script ?

My script contains a function like -

    function compareImages(picture1,picture2)
    {
         var diff =resemble(picture1).compareTo(picture2).ignoreColors().onComplete(function(data)
          {
               //console.log(data);  
          });
    return data;
   }

the 'return data' is so I can invoke this function in my java program using scriptengine and display the 'data' ( see console.log(data) in code above) in java console.

    Object res = inv.invokeFunction("compareImages", <path of image1>, <path 
                                  of image2>);
    System.out.println(res);

Nashorn comes with its own load( js ) method. You can use it to import modules

Example:

script1.js

function say(thing){
    print(thing);
}

script2.js

load("./script1.js");
say("Hi");

This should print Hi

script1 and script2 have to be in the same folder ? – source May 18 '17 at 06:45
Yes they must be in the same folder, but you can also use absolute paths or urls – Nikhil R May 18 '17 at 07:47
I have kept my JS file 'MainJS' in the same folder as resemblejs.. But getting this error javax.script.ScriptException: TypeError: Cannot load script from ./resemble.js in ... – source May 22 '17 at 05:37
maybe it's a security error? or the resemble.js is not found? – Nikhil R May 27 '17 at 11:24
