JVM in Konqueror

I am trying to get Konqueror to run an application that requires the Java Virtual Machine. The application is at : http://webbook.nist.gov/chemistry/ Do: Structure -> Use applet to draw a structure In Netscape this brings up a Java program that allows you to draw chemical structures. Once the drawing is complete, you can click on an accept button and the relevant information will be retrieved. As I say this works in Netscape but I would like to get it to work in Knoqueror. Any suggestion would be appreciated. -- Cheers, Jonathan
