TOMCAT状态404尝试了所有错误

标签： java apache http tomcat http-status-code-404

我试图在tomcat上运行web.xml文件并在其中设置server / server-mapping。显然错误日志似乎没有错误（如果我没有错），我尝试使用localhost运行它几次：8080 / Example03 / servlet1，localhost：8080 / Example03和 localhost：8080 / servlet1因为我读了一些文章发布了某些版本的tomcat的新实现..只显示http错误404（状态报告 - 请求的资源不可用）。使用v6.0 ..有没有人知道我可以尝试使其工作

从你的评论中，我建议你从头开始使用tomcat。请查看此link。

简要介绍一下tomcat的工作原理

  1. 从official website下载tomcat（下载的一个eclipse也可以正常工作，但这样你就可以了解tomcat的来龙去脉
  2. 将其解压缩到具有读/写权限的目录中
  3. 对于测试运行，转到$Tomcat_Dir$/bin并执行startup.sh或startup.bat（如果是基于Windows的系统）
  4. 在浏览器中，localhost:8080应该为您提供tomcat的默认页面
  5. 接下来，将您的应用程序打包为战争（例如myApp.war）
  6. 将此myApp.war放在$Tomcat_Dir$/webapps文件夹中，然后重新启动tomcat。您将在webapps文件夹中看到一个与war
    7. 同名的文件夹
  7. 现在http://localhost:8080/myApp将打开应用程序的默认页面（如果已配置）。否则，根据您的web.xml，localhost:8080/myApp/servlet1将触发servlet
