Calling .js file from Java

Is there any way we could call Javascript function in a .js file from Java?

Are you asking about Java running on the server (as part of a servlet or JSP), or as an applet on the client.

if the former, no. Please read this article to understand why.

My expectation is to call a javascript function in a .js file from a normal Java class file.

I don't want to call it from jsp/servlet or applet.

Without a servlet, JSP or applet, how do you expect to run this Java class as part of the web application?

It's not a web application.

I've a BPM studio which has the ability to call Java classes.

Now I wish to invoke javascript from this Java class, which now I guess is not possible.

Please comment.

The Rhino library lets you run JavaScript scripts from within regular Java classes. There was an article about that in the JavaRanch Journal last year.

Ah, you should have mentioned that. Most questions here are related to web apps. I've moved this to a general Java forum.
