FCServlet
The Java Servlet interface between the Web server and FCService provides
important benefits for FlashCONNECT users:
• Servlets increase the speed of the data transfer between the Web browser and
D3 because the servlet is loaded only one time by the Web server and is shared
among users.
• Servlets are platform independent and easy to use.
The FCServlet interface supplements the existing FCcgi and FCisapi conduits by
combining the strengths of CGI's cross-platform support and ISAPI's speed. When
invoked by the Web server, FCServlet transfers data from the Web server to
FCService. It also receives data from FCService and translates the reply back to the
Web server.
FCServlet cannot be used without a third-party Java Servlet engine. The Java
Servlet engine is not provided on the FlashCONNECT CD-ROM but is available at no
cost from the following URL:
http://java.sun.com/products/
For more information on configuring and using the FCServlet, see Testing FCServlet.
JNI Interface
The JNI interface plays a major role in the transaction between the FCServlet and
FCService. The JNI interface enables FCServlet, written in Java, and FCService,
written in C++, to communicate. There is no direct access to the FlashCONNECT JNI
interface. All access is through FCServlet.
