<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>首页</title>
</head> <body>
<html:form action="/login.do">
用户名：<html:text property="username"></html:text><br/>
密码: <html:password property="password"></html:password><br/>
<html:submit>submit</html:submit>
</html:form>
</body>
</html>不清楚是哪里出了问题。请指教。

解决方案 »

  1.   

    看一下 struts-config.xml中是否配置了login.do
      

  2.   

    <?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts-config PUBLIC
              "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"
              "http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd"><struts-config>    <form-beans>
            <form-bean name="loginForm" type="com.login.LoginForm">
            </form-bean>
        </form-beans>
        <global-forwards>
            <forward name="result" path="/result.jsp" />
        </global-forwards>    <action-mappings>
            <action path="/login" type="com.login.LoginAction"
                name="loginForm" scope="request">
                <!-- 局部URL，只有这个action可以使用 -->
                <forward name="success" path="/success.jsp"></forward>
                <forward name="error" path="/error.jsp"></forward>
            </action>
        </action-mappings>
    </struts-config>如图所示。
      

  3.   

       <form-beans>
            <form-bean name="loginForm" type="com.login.LoginForm">
            </form-bean>
        </form-beans>
    这个form-bean  里面怎么没有实体对象的？
      

  4.   


    loginForm在前面的<form-beans>里有定义啊。另外，一点击提交，浏览器的路径是：127.0.0.1:8080/login.do
