June 27, 2014 at 11:10 am #228 WebmasterKeymaster You can not verify self-signed deployment rule set jar when you don’t have the certificate installed, that was used to sign the jar file. Install the cert to Trusted Root Certificate Authorities and you will no longer get the error. Author Posts You must be logged in to reply to this topic.
