Answer 1

1. Write your self same logic in java script
2. Make a server call to your java function using Javascript using DWR

Answer 2

Javascript != Java. You cannot import a java class in javascript. The languages are different (despite the names). You need to port the code.

Unless, you want to expose the java code as a servlet and have the javascript invoke it via an AJAX request.

You can't. :) You should check out applets. Java Applets
