Are you trying to load the driver in the Server Code, or in the
Client?
You can not connect to a database from the Client Code (Browser
javascript), only from the Server code.
I am using MySql in my projects using RPC (Servlet).
In my RPC servlet I have code like this that works fine....
public Connection getConnection() throws Exception {
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection c = DriverManager.getConnection("jdbc:mysql://"+host
+"/"+db,
login, passw);
return c;
}
