OK.

Which source code?
A source code corresponding to a ".class" file archived in the ".jar"
file?
Where to see the "object" tag you are talking about?

OK.

Ok.

Ok, that is quite clear.

Ok, I do not yet understand how the JRE and applets 
work but I will soon and then everything will be clearer.
It's true that if I kill my browser I kill the RFB client too.
When I kill the browser I also kill the JRE...

Yes but it would'nt be the same process at all, would it be?
You are talking about the other solution proposed by "RealVNC" which
uses directly a client program to connect to the VNC server on port
5900, aren't you?

OK.
