I stand corrected. Since version 2.3 these are methods of the
ServletResponseWrapper. Thank you for bringing this to my attention. Tomcat
3.2 uses a servlet.jar which was updated 11/29/2000 so the capabilities of
this wrapper should be included. I tried your code and got the same result.
This seems like something that could be very interesting. Perhaps it would
be useful combined with innerHTML.?
I see you have replied. I was using the old spec. We can wait for the bug
fix then.
Best Regards,
Craig

I think they may be tomcat specific?
