Re: Postgres-jdbc example!

Try looking at the documentation

http://www.postgresql.org/idocs/index.php?jdbc.html

If you look at the error below though, you'll see that its complaining
that you are not catching the ClassNotFoundException which Class.forName()
can throw. Easiest way to get going is to say that main can throw an
exception. More normally, you would want to use try/catch to handle
the exceptions.

import java.sql.*;

public class init
{
    public static void main (String args[]) throws Exception
    {
        Class.forName("org.postgresql.Driver");
    }
}

Cheers,

Tom.
