This makes no sense. You are just forwarding port 5920 from localhost
to itself, via the SSH server, with encryption for the first half of the
journey only. "ssh -L 5920:remotehost:5902 remotehost" will do what you
(seem to) want. The "-L <localport>:<remotehost>:<remoteport>" option
means "forward all data arriving at localhost:<localport> to
<remotehost>:<remoteport>, using an encrypted tunnel for the part
of the journey between localhost an sshd-host".

Now that I read more carefully I see that my suggestion
immediately above would not work.
Perhaps I completely misunderstand what you are trying to do here.
If the VNC server is on remotehost at display :2, along with the
SSH daemon, and you want the viewer to run on localhost with an
encrypted tunnel to remotehost, and you want to use the Java viewer,
you need local ports 5802 and 5902 forwarded to the corresponding
remote ports. So you would do:
ssh -L 5902:remotehost:5902 -L 5802:remotehost:5802 remotehost
and connect to "http://localhost:5902/".
I'm sorry if I have confused the issue further :( But the method
above will certainly work for the case described.
