Hi James,
In the database URL, you have to change the word dbname with the name of your database schema.
EG: You can use a tool like MySQL Administrator to create a new schema for KonaKart, called konakart. Then the URL would be:
jdbc:mysql://localhost:3306/konakart?zeroDateTimeBehavior=convertToNull
Leave the zeroDateTime*** on the end. It's important for configuring MySQL functionality for KonaKart.
Regards,
Ming
