我的测试开始于 http://www.ejbtutorial.com/corba/tutorial-for-corba-hello-world-using-java 并且工作得很好。
因为这是使用端口1050的客户端和服务器，（在使用TCPDUMP的Linux中，我开始跟踪数据捕获并且稍后将使用WIRESHARK保存到PCAP中）
“命令行：”
root @ ubuntu：〜/ add / AdditionServer＃java StartClient -ORBInitialPort 1050 -ORBInitialHost localhost
屏幕输出：
欢迎使用加法系统：
输入：
1
输入b：
5
添加的结果是：6
在从客户端到服务器的数据捕获的某些部分：

我的问题是如何使ContextList序列长度：3到序列 长度：0使用Java代码？
非常感谢
