port number of ORACLE for JDBC

I am trying to use JDBC to connect to our Oracle database. I am using the QueryApp example from the Oreilly book "Database Programming with JDBC and Java." I keep getting "connection refused" when trying to connect with JDBC. I can connect to the database using sqlplus so I know it is up and functioning. I suspect that I am using the wrong port number in my URL for the getConnection() call. I am using port 1521 in my URL but I don't know how to find out if that is the correct port. How do I find out the port number to use in my JDBC code?

My environment is:

Sun Solaris 2.5.1
Oracle 7.2.3.3.0
jdk 1.1.4
oracle jdbc driver (latest driver from oracle - sorry don't know the version)

My URL looks like:

jdbc:oracle:thin:@myhost.mydomain.com:1521:mysid

Thanks in advance.
