I'm trying to sign a MIDlet for use on a Nokia 6600. The certificate used for signing the MIDlet is issued by Thawte, it is signed with their code signing CA cert (which is signed by the Thawte Premium Server CA certs that is on the device, so according to the MIDlet spec this should work).
The signed MIDlet can be used with WTK 2.0 OTA (after manually adding the code signing CA cert to the JAD file (Nokia MIDP 2.0 SDK and WTK 2.0 'forget' to add this intermediate cert)), the 6600 refuses to install the MIDlet. The error popup lists "Installation security error. Unable to install".
Why does the device refuse to install the MIDlet (where do I look for additional information on the error??) and/or what do I need to change to get the device to accept the MIDlet? (Changing the Trust Settings on the Thawte Premium Server CA cert doesn't change a thing)
