You could try :

    private static ScriptEngineManager mgr = null;
    private static ScriptEngine engine = null;

    mgr = new ScriptEngineManager();
    engine = mgr.getEngineByName("JavaScript");

    Object eval = engine.eval(s); // s is javascript code

Since Javascript needs some kind of Virtual Machine to run in - usually provided by browsers or programms which act like browsers (so called headless browsers), you have to use some kind of "browsing engine" (so to say) to run the page in. Perhaps WebEngine may be worth a look.
