ACTION的java代码
package service;
import com.opensymphony.xwork2.ActionSupport;
public class myAction extends ActionSupport{
public String login() throws Exception{
if(name=="111"&&password=="111"){
return "login_success";
}
return "login_failure";
}
private String name;
private String password;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;

public String getPassword() {

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

还有你eclipse中本工程的名字是WebApp_9吗？要确保和web.xml中写的一致。
<web-app id="WebApp_9" version="2.4"
另外，你要是能把错误信息发上来就更好了，先看报错，在看代码。
后来我帮你调试了，问题在这里：
<form action="user!login.Action">
修改成：<form action="user!login">或者<form action="user!login.action">追问
我这么改后是这样的哦
虽然还是404不过变了一高级一些。。会不会是好兆头。。。那个包我把struts2-blank里面的都复制到lib里面了。。
算了，给你发一个吧。我按照你的代码敲的，怎么可能有错呢。你修改完配置文件记得重启服务器。要不然就会报错。
本回答被提问者采纳<result name="login_success">/NewFile.jsp</result>
<result name="login_failure">/index.jsp</result>
</action>
这写错了，没写method，method缺省值是excute，看你的写法，应该是要调用login，所以在action标签里面加个参数method="login"追问
