我创建了以下代码。但是在 apache tomcatv6.0 服务器中运行时，第二页即 Welcome.jsp 没有加载，而第一页，即 Login.jsp 已成功加载。有人能说编码有什么问题吗？我在 Java Resources 文件夹内的 src 文件夹中创建了 struts.xml。我正在使用 eclipse IDE。

StrutsDemo.java

package com.vishnu.struts;

import com.opensymphony.xwork2.ActionSupport;

public class StrutsDemo extends ActionSupport{
    String username;
    String password;
    String returnString=null;

    public String execute()
    {
        if(getUsername().equals("abc")&&getPassword().equals("abc123"))
        {

            returnString=SUCCESS;

        }
        else {
            returnString=ERROR;
        }
        return returnString;


    }

    public String getUsername() {
           return username;
}

public void setUsername(String username) {
    this.username = username;
}

public String getPassword() {
    return password;
}

public void setPassword(String password) {
   this.password = password;
}

}

   <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="s" uri="/struts-tags"%>


<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

</head>
<body>
<s:form action="doLogin">
  <s:textfield name="username"/>
  <s:password name="password" value="Password"/>

在您的 Login.jsp 中使用以下代码。

<form action="doLogin" method="POST">
<!--
Put all the content of Web Page here.,.
-->
</from>
