MRJ can now accept certificates for signed applets. If you wish to eliminate a certificate after acceptance, you have two choices:
- Get MRJKey from the MRJ SDK. This tool will list the certificates and allow you delete selectively. MRJKey was left in the SDK because the user interface is not yet complete, but the application is usable. To get the MRJ SDK, go to http://developer.apple.com/java/.
- Delete the identitydb.obj file in the Preferences folder. This option is mentioned in About MRJ 2.2, but has the disadvantage of deleting all certificates, and requires that you reaccept the ones you really need.
