Your database vendor has made available an implementation of the JDBC framework. Put that .jar file in your classpath and you're in business; read the API documentation how to create a Connection object given the implementation.

You appear to be asking Jos to re-write tutorials that have already been written. As for a link -- check out the main Java tutorial site for the data base tutorials, and check out the help files that come with your database.
