Getting db hostname and port number from a jdbc connection

Hi
I have a connection like this.
<code>
    DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
         conn = DriverManager.getConnection(
            "jdbc:oracle:thin:@devbox:1521:UTF", "test", "test");
</code>

and I want to find out the following information from the connection.   I can get some of the information I need, but not all of it and the javadocs are not much help getting this out.  I've looked at INetAddress, but this seems to give local hostnames, not the hostname and the port number of the database I am connected to.
<code>
   try {
        DatabaseMetadata metaData = conn.getMetaData();
        String URL metaData.getURL();
        String hostname = /* How do we do this? */
        int port = /* how do we do this? */
        String DBType = metaData.getDatabaseProductName();
        String username = metaData.getUserName();
       } catch (SQLException e) {
                e1.printStackTrace();
       }
</code>
