日期格式的问题？java.util.Date?http://yoyang.iteye.com/blog/651895

Caused by: java.lang.IllegalArgumentException

java.lang.IllegalArgumentException 非法参数异常，非法参数就是用在此处的参数不正确，格式不正确什么的。

java.sql.Date.getHours(Date.java:177) 出错位置在 Date.java文件下的　１７７　行

InvocationTargetException 是一种包装由调用方法或构造方法所抛出异常的受查异常。这个异常并不是Eclipse插件开发特有的，而是标准JDK中的，它定义在 java.lang.reflect包下。在进行Java开发的时候很少会接触到这个异常，不过在进行Eclipse插件开发中则不同，很多API都声明抛出此类异常，因此必须对此异常进行处理。
