To get the port number you can implement a PipelineFactory like so.


public class MyPipelineFactory implements PipelineFactory {

   public Pipeline getInstance(Socket sock) {
      Pipeline pipe = new Pipeline(sock);

      pipe.setAttribute("port", new Integer(sock.getPort()));
      pipe.setAttribute("localPort", new Integer(sock.getLocalPort()));
      pipe.setAttribute("socket", sock);

      return pipe;
   }
}

Now to create the connection.....

PipelineFactory fac = new MyPipelineFactory();
Connection con = ConnectionFactory.getConnection(handler, fac);

Now to retrieve the port from the Request.....

public class MyService extends BasicService {

    public void process(Request req, Response resp) throws Exception {
        Attributes attrs = req.getAttributes();
        Integer port = (Integer)attrs.getAttribute("port");
        Integer localPort = (Integer)attrs.getAttribute("localPort");
 
        // etc ...
    }
}
