Java issue

When trying to open a web page with Java (1.6.0_20) I received an error message with a link for details which showed the following:

Java Plug-in 1.6.0_20
Using JRE version 1.6.0_20-b02-279-10M3065 Java HotSpot(TM) Client VM
User home directory = /Users/johncampbell

c: clear console window
f: finalize objects on finalization queue

p: reload proxy configuration
q: hide console
r: reload policy configuration
s: dump system and deployment properties
t: dump thread list
v: dump thread stack
x: clear classloader cache
0-5: set trace level to <n>
----------------------------------------------------
I can't find a download for version 21, and I have no idea what to do with this message. I have been told that this page runs perfectly on Windows - is there a Mac solution?

Thanks fo any help

Which browser is showing that message, it it just Safari or have you tried Firefox or Chrome as well

I've tried on safari and firefox, but no joy.
