1·tcpmon类把任何发往端口8070的SOAP信封都写到跟踪窗口并将其发送到本地主机端口(localhost port) 8080。
The tcpmon class writes any SOAP envelope that comes to port 8070 to the tracing window and sends it to localhost port 8080.
2·这会在8070端口启动一个TCP服务器，它在任意一个客户端与本机的8080端口(在本例中，由Tomcat提供)之间扮演一个中介的角色。
This starts a TCP server on port 8070 that ACTS as an intermediary between any client and port 8080 on the local host, which in this case is serviced by Tomcat.
