I have this script file created using phantomjs
var webPage = require('webpage');
var page = webPage.create();
page.open(URL, function (status) {
var content = page.content;
console.log('Content: ' + content);
phantom.exit();
});
now I want to use this script in a Java program but I can't. I do this in my project
ScriptEngineManager s = new ScriptEngineManager();
ScriptEngine se = s.getEngineByName("JavaScript");
se.eval(new FileReader("myScript.js"));
but `this is the result

edit: I put this line in my code:
Process process = Runtime.getRuntime().exec("/usr/bin/phantomjs myScript.js");
but this doesn't work. The progrma returns the same errors as before. what can i do??

Require is not a part of standard javascript, but a feature of NodeJS. Your JAVA program doesn´t know how to deal with it.

The scripting engine doesn't have access to objects (require) added to JavaScript by PhantomJS/nodejs
You can execute phantom using exec. Something like
// You need the correct path for phantomJs
Process process = Runtime.getRuntime().exec("/usr/bin/phantomjs myScript.js");
