Creating application packages
The creation of application packages consists of editing the JAD file and
building the project.
If you have a mobile Java project and want to run it in an emulator in
MTJ, you must first build the project in order to create the JAR file.
The build process also creates a JAD file, which you need to edit according
to Java ME specifications before deployment.
If you have code for an application and want to test it in MTJ, you must
create an MTJ project for the application. In addition, with the code,
you can create different application packages for different configurations
and devices.
After
testing the application in the emulator, also consider testing the application
in the target device. This way the possible errors in the emulator can
be detected.
