# MIDlet Tab

The MIDlet tab helps you to control the method via which Eclipse launches the debug session.

The properties configurable in this tab are:

Option | Description
--- | ---
Project | The project to be launched. Either type a valid project or click Browse to select a a project via a dialog.
MIDlet | When MIDlet launching is specified, the emulator is instructed to execute the MIDlet from the local file system. Using this method of launching, it is not necessary to package the MIDlet prior to debugging. When you select this option, you must provide the name of your MIDlet class.
JAD URL | When JAD URL is specified, the emulator loads the specified Java ME Application Descriptor specified in the text field. The specified JAD and the associated JAR file must be valid for launching. There is no build or packaging done when this option is selected.

Over The Air

When Over the Air is specified, the Eclipse emulator's Java Application Manager (JAM) will be instructed to contact MTJ's built in HTTP server to download the suite. Starting with version 0.5.5, the Over the Air Preferences default to automatically deploying the project prior to launch. If you have disabled this feature, you will need to manually deploy the project prior to using this mode.
