HTTP is an ideal client/server communication protocol for mobile Java applications [HTTPMIDP]. Per specification, every MIDP 1.0 compatible device must support HTTP. Other protocols such as TCP or UDP (User Datagram Protocol is a connectionless transport) are basically optional for a MIDP 1.0 device. Since not all MIDP devices support a socket or datagram-based communication, HTTP deployment on the mobile device permits optimal portability between devices from different manufacturers. Although some devices like the Nokia 6800 handset support socket connections, for maximum compatibility HTTP should be used as the transport protocol between client and server.
