APPENDIXC

Connecting to the Wireless Toolkit’sWMA Emulation Environment

The J2ME WirelessToolkit supports the Wireless Messaging API (WMA), which

enables you to send and receive SMS or CBS messages. The WirelessToolkit’s

support for messaging includes automatically assigning phone numbers to

emulators and routing messages between them. Youcan develop and test WMA

applications entirely within the WTK environment. For information on the WMA,

see http://java.sun.com/products/wma.

However,if you want to send or receive WMA messages to programs outside of

the WirelessToolkit environment, you can use the extension API that is provided

by the WirelessToolkit. By using the extension API, you can:

■Send or receive SMS or CBS messages from the emulation environment in the

WirelessToolkit to or from J2SE programs outside the Wireless Toolkit

environment. This enables you to communicate through WMA messages

between MIDlets within the WirelessToolkit emulators and an external J2SE

program. This external program can provide whatever functionality you

program it to have, for example, imitating a service that responds to WMA

messages.

■Create a component that acts as a messaging gateway.You can write your own

J2SE program that registers itself with the WirelessToolkit as a default gateway.

The WirelessToolkit will forward all messages from within the Wireless Toolkit

environment that do not have a recognized destination phone number to the

default gateway.This enables you to extend the Wireless Toolkit WMA

environment to other message routing environments, for example, an actual

Short Message Service Center (SMSC).

Forinformation on the extension API, see the {j2mewtk.dir }\docs\wtk\wmaBridge

directory.
