【IT168 技术文档】这是两个Java bean应用的例子，实现航空预定机票的功能。
预定构件功能说明：
1，预定构件应包含二个面板，预定座位面板与乘客面板
2，在装入预定构件时不应有可用的乘客面板
3，当用户打入要预定的旅行地点.旅行日期及座位号时：
(1)首先，应按以下格式生成乘客号：
(2)其次，在显示乘客号时应使乘客面板是可见的(注意：你可能重定BeanBox窗口中bean大小，以观看此乘客面板。而且，如果打入座位号为0，则不应显示乘客面板。)
(3)当用户点击乘客面板的submit按钮时，此面板的所有域控件中文本应置为空
(4)上面步骤被重复，直到所接收的乘客材料个数等于预定的座位数为止
4，在已预定了所需座位号之后，给出所预定座位号的消息框应被显示d
5,乘客面板应作为bean创建，可以把嵌入在铁路预定应用或航空应用中
6，你需接受以下格式之一的旅行日期"dd/mm/yy","mm/dd/yy","dd-Month-yy"
