Platform Detection in J2ME

J2ME provides system properties which can be used to detect the platform you're running on. This is useful for writing platform-specific code such as serial communication.

System.getProperty("microedition.platform");

On a Windows Mobile 5 smartphone, the IBM J9 VM returns "Windows CE 5.1,Smartphone" followed by the phone model. However, the built-in JVM returns "intent JTE" instead. On a Nokia N90, it returns "NokiaN90-1/5.0607.7.3".

J2ME server socket and camera API

MIDP 2.0 introduces support for running a local server using ServerSocketConnection, as well as support for camera capture (photo and video).
