Having an emulator does not eliminate the need to test your application on actual target devices. An emulator can only approximate a device’s user interface, functionality, and performance. For example, an emulator may not accurately simulate processing speed, so an application may run faster or slower on a target device than it does on an emulator.
Java ME SDK simplifies deployment to and debugging on real devices running the Sun Java runtime. This version supports Windows Mobile platform based devices, and includes a bundled Java runtime for Windows Mobile devices.
The Microsoft Device Emulator is an example of third-party emulator integration. It means you can deploy applications to Microsoft Device Emulator as easily as you can run on our built-in emulators. See the following topics: CLDC Emulator Installation for a Device Running Windows Mobile and CLDC Installation for Windows Mobile.
