下面是我用struts标签写的表单：
<%@ page language="java" pageEncoding="gbk"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean"
prefix="bean"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html"
prefix="html"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-logic"
prefix="logic"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-tiles"
prefix="tiles"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-template"
prefix="template"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-nested"
prefix="nested"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html:html locale="true">
<head>
<html:base />
<title>insert.jsp</title>
</head>
<body bgcolor="pink">
<html:form action="insert.do" method="post">
id:<html:text property="id"></html:text>
<html:errors property="nid" />
<br>
name:<html:text property="name"></html:text>
<br>
<html:errors property="nname" />
<br>
address:<html:text property="address"></html:text>
<br>
email:<html:text property="email"></html:text>
<br>
<html:submit value="提交" />
<html:reset value="重置" />
</html:form>
</body>
</html:html>
启动服务器之后跳出下列错误：
好像是提示action mapping没有找到或者是没有找到formbean中的集合
我连表单提交都没有提交怎么会有集合元素呢？
到底怎么回事啊？
----------------解决方案--------------------------------------------------------
servlet 异常，说明你的insert.do
获取信息不正确或读取信息不正确，请检查一下。
----------------解决方案--------------------------------------------------------
没有啊，我连表单都没有显示啊，根本连提交都没有提交，actionForm里怎么可能接收到数据呢，读不到任何信息啊，我用的ide是eclipse3.2.0+myeclipse5.1.1ga
----------------解决方案--------------------------------------------------------
虽然你没有提交,它也是会检查的!
----------------解决方案--------------------------------------------------------
这是我的formbean

我没有发现什么错误啊
----------------解决方案--------------------------------------------------------
因为你没有创建 InsertAction ,struts首先运行的是Action,因为它是处理类,根据配置文件来进行处理,你没有这个Action,当然会报错,不信你创一个Action试试看
----------------解决方案--------------------------------------------------------
action类写错了
----------------解决方案--------------------------------------------------------
你把这些东西都去干净就对了。
<html:errors property="XXX" />
----------------解决方案--------------------------------------------------------
