你将struts.xml中的<action name="LoginAction.action" class="com.chinasoft.demo.login.LoginAction" >
改为LoginAction
<action name="LoginAction" class="com.chinasoft.demo.login.LoginAction" method="CheckLogin" >,一个是去掉.action,二是指明你调用的方法
这个好像是你的web.xml中要改一下，里面的action对应不上。
没看出来有什么不对，这个找不到一般都是struts.xml里面定义相应的action或者定义了但是使用的path不对。吧这个namespace="/" 去掉试试。
<form action="LoginAction.action" >你表单里提交的是LoginAction.action，通过web.xml的struts过滤器会在你的struts.xml中找到name值为LoginAction的action，可是你的action的name是LoginAction.action，对应不上，另外你修改name值为LoginAction后还要指明你要调用哪个方法啊
配置文件的action没有映射到
<action name="TeString" class="com.demo.Ta" method="TeString">
       <result name="success">/test.jsp</result>
</action>还有你的action都有问题，建议LZ先去学习下基本的东西!!
Struts配置文件中的action   name配置去掉.action。   指定具体要执行的method默认执行execute方法
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>
貌似楼主没有加上这个  页面必须指定项目路径
偶刚学，弱地问一下~~ LoginAction 不是要继续ActionSupport 的吗
我现在也在学习这个呢，推荐一个博客

public class LoginAction {private String username;
private String userpass;public void setUsername(String username) {
this.username = username;
}  public void setUserpass(String userpass) {
this.userpass = userpass;
}

public String execute() {
// TODO Auto-generated method stub
System.out.println("您好："+ this.username);
// return null; 返回要有值。
return SUCCESS;
}
//step2:处理请求数据
public boolean CheckLogin()
{
if("abc".equals(username)&&"123".equals(userpass))
return true;
else
return false;
}
}

<form action="LoginAction.action" method="post">

<input type="password" name=“userpass”><br>
大概有这些错。具体我没有调试
我知道我的action中有问题，（那个继承是我忘记复制了）数据没有得到，在后台打印的是null，但是我是真的不知道哪有问题啊！！！！求帮忙！！老师的要求还必须是另写一个类判断验证，（不用连接数据库）而不是在execute中判断【我刚接触strut，老师就留了这个作业实在是不会，原来还在MVC中，现在转到框架真的不明白】
我改了，但是还是有问题，在success.jsp这个页面应该显示“欢迎  success.jsp ，登陆~”
