Answer 2

上面的代码有点错误
<html:form action="updateClient.do" method="post" enctype="multipart/form-data">
应该是
<html:form action="updateClient.do" method="post">下面的用来更新的Action上面的页面就是用它来处理的
但是根本就没进到这个类的方法里来package com.fund.struts.action;import java.util.Date;import javax.servlet.http.HttpServletRequest;

client.setClientName(clientName);
client.setIdCardNo(idCardNo);

}
}

Answer 3

把这个searchResult.jsp 贴哈`

Answer 4

java.lang.IllegalArgumentException: argument type mismatch
类型不匹配在你点update时，要先把页面表单装到form里吧，这时候出的错javax.servlet.ServletException: BeanUtils.populate
发布bean的错误

Answer 5

的确是form里的类型不匹配的问题,日期类型错误了
