I am trying to use the new LiveConnect features introduced in Java 6 Update 10.

Code looks like this (copied from the applet tutorial):

 Class<?> c = Class.forName("com.sun.java.browser.plugin2.DOM");
 Method m = c.getMethod("getDocument", java.applet.Applet.class);
 Document document = (Document) m.invoke(null, this);

But all I am getting is a ClassNotFoundException for the entry-point class.

This on the Mac, 10.6, with both Firefox and Safari.

Java Plug-in 1.6.0_22
Using JRE version 1.6.0_22-b04-307-10M3261 Java HotSpot(TM) 64-Bit Server VM

Is this not implemented on the Mac? Or do I need to configure something?

All I need to do is get and set the value of form elements on the page, so I would be fine with an older (pre-6u10) API if that works better.
