After you have created all the necessary files for the project, you can build the project and run the application in an emulator.
Note: The MIDlet used in this example was built using the Eclipse IDE. Please see the instructions for building MIDlet projects for Eclipse in section Building the example application.
You can also construct them using command line or other IDEs of your choice.
The example is also provided on Forum Nokia. Instead of creating the example from scratch as shown in this document, you can download the example files and run them immediately with your SDK.
