After you have created your MIDlet application, you need to do a build to generate the JAR/JAD package. The build process compiles the resources of an MTJ project.
Note: A successful build is a prerequisite for successful running of the application in an emulator.
To build an MTJ project
To build an MTJ project, you need to have an MTJ project open in your workspace.
If the build process is successful, a deployed folder appears under the project in the Navigator view. The folder contains the JAD and JAR files that were generated with the build process.
Note: Projects that have been previously signed before building are automatically re-signed during the build process.
