我正在编写我的第一个struts示例.i遵循了确切的步骤但是即便面对这个问题，也不知道什么错误的代码正在我的老师的机器上工作但我的不是，我认为我正在做一个小错误plz帮我找到 1）我有index.jsp
<%@ taglib uri="/struts-tags" prefix="s" %>
<s:form action="login">
<s:textfield name="username" label="username:"></s:textfield>
<s:submit></s:submit>
</s:form>
2）具有Loginaction类（pogo类）的bean包
package bean;
public class Loginaction {
String username;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String execute()
{
return "success";
}
}
3）struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<package name="demo" extends="struts-default">
<action name="login" class="bean.Loginaction">
<result name="success">welcome.jsp</result>
</action>
</package>
</struts>
4）welcome.jsp
<h1>hi user.</h1>
5）web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_9" version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

答案 0 :(得分：0)
这意味着进程已经在使用端口8080.通常，通过启动tomcat实例而不关闭前一个实例来启动新手。你应该检查一下。此外，可能已经有另一个服务侦听端口8080.如果是这样，您需要确定使用端口8080的进程。
我的建议是，您了解系统中可用的工具，这些工具可以帮助您回答以下问题：
1）正在运行哪些进程？
2）哪些网络端口已打开以侦听传入请求，又称哪些是服务器？
一旦你能做到这一点，你就会知道如何识别冲突的过程，然后你只需要关闭它。
答案 1 :(得分：0)
尝试查看您看到错误的计算机上的所有tomcat和Java进程，然后再次尝试启动tomcat。在您的情况下，8080已被另一个进程使用。先杀了，然后再试一次。
答案 2 :(得分：-1)
只需更改 server.xml 文件中的tomcat服务器http端口nb，保持原样。
按照以下步骤执行此操作：
<---Define a non-SSL HTTP/1.1 Connector on port 8080----> <Connector port="8090" ..........> RAAM
