I got the same problem too. Even more,I got the information :
No rtp package. 1. I am wonder about the :import rtp.*; Did you got a rtp package? 2. ParticipantListWindow is not found. Do you have solved it?

Solution:
delete all references of ParticipantListWindow and delete import *.rtp.

Does anyone have the code for rtpclient.html or the directions on how to run this applet? Will it listen to a stream from JMStudio so I can see myself in a web cam on a different computer?
Thanks,
Siegfried

OK, here is what I got so far (see below). It is giving me this error. Can someone guide me on signing this applet and setting up the appropriate policy file?
Thanks!
