这个是update_user.jsp布面首先它会显示选择的user信息。然后可以进行修改。
但是点保存出现在以下错误 。
javax.servlet.ServletException: BeanUtils.populate

[解决办法]
servlet和这个javabean绑定了吗？报的错是没有指定的bean!
[解决办法]
org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:432)
dopost方法这里有问题,看一看servlet里面是不对应,或把jsp改成get方法,试一下
[解决办法]
form的配置有有没有问题，报错是form的问题，在action里面设一个断点肯定到不了，form-bean的配置文件呢？
[解决办法]
html:text name= "userForm " property= "updateUser.password " >
中的name是text的名字,自己取个
property改为property= "password "
其它的都照着这个改下
[解决办法]
先说一下你的代码有个问题了.
一你用了ActionForm还用什么javaBean?
二标签里的name是对应的表单所连接的action所对应的form所以可以不用写
三标签里只写property属性就行了是form里的元素
4你想这样的获取整个类.有必要吗?
