没有试过，GOOGLE了一下：
JSP中没有import java.uitl.Date或者很可能import java.sql.Date，所以出现了这个问题。java.util.Date的构造函数支持无参构造，java.sql.Date不支持。

解决了，好像是编码问题！

[ylyqsm]

500错是表示web服务器找不到你请求的页面！！

也就是说你写的jsp产生了错误导致在运行时，web服务器不能将其编译成servlet

[iskyshop]

org.apache.jasper.JasperException: /usershow.jsp(1,1) Page-encoding specified in XML prolog (UTF-8) is different from that specified in page directive (utf-8)
编码没有统一,jsp页面代码
[table=90%][tr][td]CODE:
<%@ page language="java" c
pageEncoding="utf-8"%>”
[/td][/tr][/table]
多了一句pageEncoding="utf-8"，而这句代码是eclipse自动生成的。删除后一切正常

utf-8改成UTF-8
