Oracle Lite & Coldfusion

Hi, I'm having yet another crisis, about the 10th today.  To make a long story short, I installed Oracle 10 lite on my machine. I ran some sql stuff to set up the default db that gets installed with that.  Now I need to run this with Coldfusion MX 7.  However, I can't set up the datasource in the coldfusion administrator.

This is the error I get when I try to use ODBC sockets:

# Connection verification failed for data source: Polite
java.sql.SQLException: [Macromedia][SequeLink JDBC Driver]TCP/IP error, connection reset by peer.
The root cause was that: java.sql.SQLException: [Macromedia][SequeLink JDBC Driver]TCP/IP error, connection reset by peer.

I set it up using ODBC this way:

DSN  - Polite, SID name - Polite, Server (servername), username system, password master

I'm not really sure what the SID name is supposed to be.  I've tried a few things already.

This is the error I get when I try to use ODBC:

Connection verification failed for data source: Polite
java.sql.SQLException: [Macromedia][Oracle JDBC Driver]Error establishing socket. Connection refused: connect
The root cause was that: java.sql.SQLException: [Macromedia][Oracle JDBC Driver]Error establishing socket. Connection refused: connect

Now, I don't know oracle at all.  I know enough to run someone else's scripts.  I would really appreciate any help at all.

Thanks!
