項目是年代久遠的了，用的是jdk1.4，登錄驗證需要加mac地址驗證，而且是需要兼容主流平臺的操作系統。
得，任務落到了咱的頭上，啃之。
考慮到jdk1.4沒有API取得mac地址，故使用系統命令cmd ipconfig /all 截取mac地址。但考慮到環境變量的改變有可能影響到 ipconfig命令的執行，而ipconfig.exe命令在操作
系統的路徑是c:\windows\system32\ipconfig.我們只要獲取到環境變量中windir的值，即c:\window
貼上該類，jdk1.4下，在winxp(包括虛擬機)、win2003(包括虛擬機)、win7(聯想)均通過，linux和unix沒測試。如有錯誤，歡迎指正。
