programming interface has been designed to beindependent of the underlaying protocol. You can easilyswitch from one transport facility to another one, withoutneeding to change your your application. The jSMSLibrary requires only 180KB and can therefore also be

used in Embedded Devices.

Message and Sms Message

The base class for all messages (exceptMMS) in thejSMS API is called Message. A Message object canbe sent as an SMS (by using one of the SmsService

implementations) or as an email (using theSmtpService). If you want to have more control aboutthe content and attributes of a SMS Message, theclass SmsMessage should be used. SmsMessageextends the base Message class and adds additional

features like specifying the message's characterencoding (alphabet), setting the validity period of themessage, requesting a status report, etc.
