I have a signed MIDlet I cannot install on my device. Is there any way to install this MIDlet?
Check that all the required permissions are requested in the JAD file. You can also try removing the MIDlet-Jar-RSA-SHA1: and MIDlet-Certificate-1-1: entries from the JAD file (your signed MIDlet will now be treated as unsigned midlet). If the installation still fails, check that the JAR file size attribute is correct in the JAD file. Make also sure that all the JAD properties are set a non-empty value.
