The procedure for signing MIDlet suites with real keys works like this:
1. Generate a new key pair. In the J2ME Wireless Toolkit you can do this by
pressing New Key Pair... in the MIDlet signing window, as described above.
2. Generate a Certificate Signing Request (CSR). Press Generate CSR... in the
signing window. To change the location of the CSR file, enter a new path or
press Browse... and choose a new file location. Press Create to write the CSR file.
After the CSR is written, you’ll see a message that indicates success.
3. Send the CSR to a certificate authority (CA). The CA will need more information
from you to verify your identity. You will also need to pay the CA for the
certificate they generate for you.
4. Once the CA has verified your identity and taken your money, you will receive
a certificate from the CA that certifies your public key.
5. Import the certificate into the J2ME Wireless Toolkit by pressing Import
Certificate... in the MIDlet signing window.
You can now use your own private key to sign MIDlet suites. The J2ME Wireless
Toolkit will take care of the details of placing the signature and your certificate into
the MIDlet suite.
6.4.3 Importing an Existing Key Pair
You may have keys in a J2SE keystore that you would like to use for MIDlet
signing. In this case, you need to import your signing keys to the J2ME Wireless
Toolkit so that you can sign your MIDlet suite. To do this from the MIDlet signing
window, click on Import Key Pair... Select a file that contains a J2SE keystore. You
will be prompted for the keystore passphrase. Then select the alias for the key pair
you wish to import. Finally, you will need to select a protection domain for the key
pair’s root certificate.
6.4.4 Removing a Key Pair
To remove a key pair from the MIDlet signing window, select its alias and choose
Action > Delete Selection
.
6.5 Managing Certificates
You’ve already heard about the emulator’s list of root certificates. In this section,
you’ll learn how you can manage this list using the J2ME Wireless Toolkit.
