Wireless Messaging API (WMA):
The Wireless Messaging API (WMA) is an optional package for the Java 2 Platform,
Mobile Edition (J2ME) that provides platform-independent access to wireless
communication resources like Short Message Service (SMS). Currently WMA can be
used on top of CLDC and MIDP, but could also be implemented on CDC-based
devices.
Package javax.wireless.messaging:
To send a SMS, you have to use the Generic Connection Framework from Java ME
using a protocol sms://. WMA API offers the following classes:
