Java监控AS400 Job，并使用CORBA通过Domino发送邮件

 　　写了一个Java swing小程序，用于监控AS400的Job状态，并定时通过CORBA链接Domino发送邮件。这是核心的一个类（中断了几年的Java学习，现在看来部分细节处理的不是很好，分享嘛，无所谓，呵呵）。两个要点是：1，如何使用JTOpen包操作AS400对象；2，利用CORBA操作Domino对象。

　　准备工作：1，引入最新的JT400.jar；2，引入Notes目录下NCSO.jar（可以到其他电脑拷贝，CORBA的好处就是不需要安装Notes客户端）；3，Domino开始DIIOP服务（可以Google）。
