What is the difference for Internet Deployment between the Forms Listener and the Forms Listener Servlet?
The Forms Listener is a process running on a specific port on the server machine. Because the Forms Listener manages the initial connections from the Forms client, the machine where the Forms Listener process is running and the port on which the Forms Listener is listening must be exposed through the firewall for HTTP and HTTPS traffic. When the connection between the client and the Forms Runtime process is established, the client and the runtime process requires that the connection be persistent. To achieve this persistent connection through firewalls and proxies Oracle requires that firewalls and proxies be HTTP1.1 compliant. The Forms Listener Servlet is a Java servlet running in a servlet engine. The Forms Listener Servlet improves upon the functionality of the Forms Listener. In the Forms Listener architecture the Web server routes the client requests for the Forms Listener Servlet directly to the servlet instance. Because the web server acts like the end point for the client, the
