FCServlet provides an alternative path for the flow of data between the Web server and FCService.
The path contains three stages:
FCServlet gets the request from the Web browser via the Java Servlet engine and passes the request to the JNI interface.
The JNI interface translates the environmental and form variables and passes them to FCService.
FCService passes the request to D3 which processes the information and sends back the result along the same path ending at FCServlet. FCServlet then passes the data back to the Web server.
The following diagram illustrates the three possible paths through which the Web server and FCService can communicate.
