Some network/security guy is telling me he needs to know which port to open up on his network in order for an applet on our website to run in their browsers. Is this true? I don't see anywhere in our simple applet's code where anything like this is specified. It loads up an image that is passed to it as a parameter, so I don't see why it would send a message back up to our site (but he says he can see it going back out, and because it never loads in the browser, he assumes he needs to know what port to open up so it can come back in). I kind of thought that if the webpage loads, then the applet files have been downloaded along with it, and since the image gets passed as a parameter, there is no need for it to "go back out" over the net again, but I suppose I was wrong about this...

No extra ports needed. Just plain old port 80 (the HTTP port). It must be a configuration problem in the browser... like disabling java or something.

It's not a port problem. I've had web servers with ONLY port 80 open, and they spew out java applets like there's no tomorrow.
