A guide on incorporating java.type into your JavaScript code

I've been attempting to utilize the following command in my JavaScript:

var file = new Java.type("java.io.File");

Unfortunately, I'm encountering an error:

Uncaught ReferenceError: Java is not defined

Can anyone provide guidance on how to successfully integrate this Java library into my code? I need it for executing functions like file.listFiles().

Thank you in advance.

Answer №1

It seems like you are referring to this particular Java functionality.

To access the Java Scripting API, you will need to utilize a JavaScript engine that makes the API available through the global Java object.

Currently, there is no modern JavaScript browser runtime that supports this feature. However, older platforms like Netscape Navigator 4 may have had some level of support. If you require this capability, consider using Rhino to run your JavaScript code outside of a web browser.
