Programming Wireless Devices with the Java 2 Platform

MIDP target devices operate on a wide variety of wireless and wired networks with incompatible transport protocols. In addition, wireless networks have less bandwidth, more...

Characteristics of Wireless Data Networks The MIDP Specification version addresses two types of wireless data networks: circuit-switched data (CSD) and packet-switched data (PSD). A wireless circuit-switched...

MIDP devices must support the HTTP protocol, a rich, widely used protocol that can be implemented relatively easily over a variety of wireless networks. HTTP...

The interface javax.microedition.io.HttpConnection defines the MIDP HTTP API. This interface is unchanged from MIDP 1.0. The interface extends the interface javax.microedition.io.ContentConnection to provide additional fields...

Sample Code (NetClientMIDlet.java) The following application, NetClientMIDlet, demonstrates how HTTP can be used to log in to a server, send data, and receive a response. The MIDlet...

The interface extends interface javax.microedition.io.StreamConnection to define the API to TCP/IP or similar socket streams. (Refer to the documentation of interface StreamConnection on page...

ServerSocketConnection The ServerSocketConnection interface defines the server socket stream API. A server socket connection is not a socket or stream connection; it only establishes that...

UDPDatagramConnection The UDPDatagramConnection interface extends the interface java.microedition.- io.DatagramConnection to define a UDP datagram connection. (Refer to the documentation of interface DatagramConnection on page 69.)...

CommConnection The CommConnection interface defines an API for a logical serial port connection. The CommConnection extends the StreamConnection interface, through which bytes are transferred using...

New for MIDP 2.0 MIDP Specification version introduced several new network and communication APIs. The SocketConnection API can be used for reliable connections with servers...
