struts-config.xml里定义的/login.do没有对应的form类，查查看form-beans标签定义里有没有form类，action标签有没有引用该form bean

[chaomy]

你用的是struts吧?
在你的程序里引入struts包了吗?
没有struts包时,<html:errors/> <html:form/> 等标签都是不能识别的

配对成功也报错，J2EE的这些框架太垃圾！

<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
上面的这个（struts的标签库）加了吗？
action="/login.do"前面的斜扛不要的．
