To export the certificate as a file the keystore command must be adjusted:

•Replace [keystore path] with the keystore file path (e.g. C:\keystore\UTI_Keystore)

•Replace [certificate path] with the destination path (e.g. C:\temp\UTI.cer)

keytool -exportcert -keystore [Keystore path] -alias tomcat -file [certificate path]
