Problem Installing 4.05 (MySQL setup, error)

When setting up Jahia using the included wizard, when configuring the MySQL
DB connection, I get this error (I used the default URL w/o luck, specified
the port w/o luck):

Error while connecting to the database with
url=[jdbc:mysql://localhost:3306/jahia] user=[jahia] password=[XXXXXXX]:
Communication link failure: java.io.IOException, underlying cause:
