Java - JDBC Oracle Thin Driver problems

I'm trying to connect to an NT server running Personal Oracle 7.3.2. I am using the JDBC Thin Client from Oracle and am trying to connect using this URL - jdbc:oracle:thin:192.168.1.4:1521:PROD. When I do this I get a java.sql.SQLException: Connection refused. I think the problem can eather be that I have the wrong port number, wrong SID or I need to set up DNS insted of using the the IP numbers. Can anyone tell me how I can set the port and SID? I took a look at the SQL*Net easy setup but it came back with an error that a file was already modified and I didn't want to mess anything up.
