About MIDP Signing and Security

See Also

Signing a MIDlet suite allows MIDP devices to verify the integrity and origins of your MIDlet suite. MIDP devices use signing information to check an application's source and validity before allowing it to access protected APIs. To sign a MIDlet suite, you create a key pair:

Each certificate has a designated security domain. Once your MIDlet suite has been verified, it can access any of the protected APIs permitted by its security domain.

Although the security domains available vary from device to device, the following security domains are supported by the IDE and the default emulator platform, the Sun Java Wireless Toolkit:

You can sign a MIDlet suite by:

You then have to export the certificate and set its security domain in each emulator.
