I've made a simple JAVA program to show a HTML page. But I cant seem to get the JAVA SCRIPT on the html page to work in the program. I use it to make calculations. If I open the HTML page in the browser it does work. Can someone help how i also get it to work in my JAVA program?

Standard java ponents support very basic HTML only. They do not support either JavaScript or any advanced elements introduced during that last 10 (or may be even 15) years.

You should use pure java browser. There are several implementations. The following discussion may help you: Pure Java HTML viewer/renderer for use in a Scrollable pane

JEditorPane doesn't support Javascript. The easiest alternative would be to use either JxBrowser (mercial) or SWT's Browser widget.

Try using Rhino to process the javascript... Otherwise it's a dead end.

Please take a look at the swt browser ponent, but I too would remend rhino, if all you want is running putations written in js.
