Hi,
You have to store the configuration settings in suncertify.properties and that is a must. I don't think there is a must on how the data should be stored, so xml, plain text, binary,... everything is allowed.
But of course why making it hard for yourself, if there is a
Java class which is made perfectly for the job (java.util.Properties): loading, saving, retrieving properties is as simple as possible with this class.
Kind regards,
Roel
