Re: 2-way RMI-Connection

If you are using applets is it your intention to deploy this on a
website for public use?  You are going to encounter many problems with
firewalls and the like with this two way connection scheme.  Have you
already decided not to go with a polling routine from client to server
to check the status?

I have done this with standard java/swing applications but never from an
applet, I would imagine that you need to bind the listening port as part
of the constructor, or during the initialization, for the client and
then you just pass the ip address of the connection back to the server.
This also requires that the stubs are at both ends so you need to have
all the interfaces and what not set up that way as well.

I don't know if that helps but if you need I could dig up some sample
code that I have here somewhere from the application that I wrote doing
that.
