Answer 1

建议你使用日期控件，一般日期的格式需要定死，这样不容易出错
你这里报错的原因是：你这个字段是date类型，但你传到后台的是字符串，这样不匹配造成了报错！
你把date类型写成string，然后到后台转换就可以了！！！

Answer 2

Caused by: java.text.ParseException: Unparseable date: "1983-07-01"
日期无法解析，也就是说不识别了，看看数据库里要求日期是什么格式

Answer 3

是类型转换错误，画面输入的格式是根据操作系统的Locale来定的。可以尝试一下：2009/09/08。

Answer 4

页面得到java.text.DateFormat，和action预期要得到date的日期格式不符合

Answer 5

页面是否可以通过function void changeDateText(){}   js把string 保存，到后台使用转化为date类型

Answer 6

多谢各位！
日期输入用的是my97的日期控件。在windows下正常，后台打印出来的的内容是：
The date is :Tue Sep 08 00:00:00 CST 2009
而在linux下则报上述错误。

Answer 7

在Action中定义为String，同时在页面上设置日期字符串格式，然后再转换。通过这种方法来解决的。
