My application needs to implement callbacks for web browsers behind firewalls. The only way I know this can be done (without polling) is to use RMI.
I remember reading in
Java Servlet Programming (1st Edition) about doing this on Port 80 with RMI -- there were foot notes referencing some javatips on
www.javaworld.com. Unfortunately, I don't have my first edition any more!
I'm looking thru the second edition of Java Servlet Programming by Jason Hunter and I cannot find find any references to using Port 80. Does Java RMI with Applet/Servlet connections still use port 80?
If I install
http://java.sun.com/products/plugin/ on IE, can I do RMI call backs?
thanks,
Siegfried
