跟着传智播客的视频学struts1在MyEclipse中建的目录，导入相关的包，输入http://localhost:8080/strutstest1/这个路径报404错误为什么？我知道他没有在Webroot目录下建index.jsp文件，为什么他的可以出来我的出不来？
strutstest1
----src
-------cn.itcast
------------LoginAction.java
------------LoginForm.java----WebRoot
-------WEB-INF
-----------struts-config.xml
-----------web.xml
-------Login.jsp
-------LoginFailure.jsp
-------LoginSuccess.jspweb.xml文件
<servlet>

我是不是少了什么东西？

<welcome-file>Login.jsp</welcome-file>
</welcome-file-list>
在配置文件末尾加上一下配置信息就可以了
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<welcome-file>Login.jsp</welcome-file>
</welcome-file-list>
可以，但是我有不明白为什么他的web.xml什么没有就可以访问这个路径http://localhost:8080/strutstest，而我的却不可以？
我是跟着视频里走的谁知刚开始就这样http://dl.dbank.com/c0isp3n365这个网址中的03是我看的视频....
代码是这样的：
cn.itcast包中的java文件为：
LoginAction.java
package cn.itcast;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;public class LoginAction extends Action { @Override
public ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response)
throws Exception {
LoginForm loginForm = (LoginForm)form;
if(loginForm.getUsername().equals("itcast")){
return mapping.findForward("loginSuccess");
}else{
return mapping.findForward("loginFailure");
}
}
}
LoginForm.java
package cn.itcast;import org.apache.struts.action.ActionForm;
@SuppressWarnings("serial")
public class LoginForm extends ActionForm {
private String password;
private String username;
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}

你把
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
删除了就找不到Webroot目录下index.jsp了
或者加上
<welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
因为你已经把index.jsp删除了
说的对，你按wen157604891说的仔细查看下
