当Tomcat在Eclipse中运行时，无法打开http：// localhost：8080 / [英] Cannot open http://localhost:8080/ when Tomcat is running in Eclipse

问题描述

我在这里提出了同样的问题：我可以打开在浏览器中 http：// localhost：8080 / ，但仍无法访问演示网页..

 <？xml version =1.0encoding =UTF-8？> 
< web-app xmlns：xsi =http://www.w3.org/2001/XMLSchema-instancexmlns =http://java.sun.com/xml/ns/javaeexmlns ：web =http://java.sun.com/xml/ns/javaee/web- app_2_5.xsdxsi：schemaLocation =http://java.sun.com/xml/ns/javaee http：// java.sun.com/xml/ns/javaee/web-app_2_5.xsdid =WebApp_IDversion =2.5>

< welcome-file-list> 
< welcome-file>的index.html< /欢迎-文件> 
< / welcome-file-list> 
< / web-app> 
  

PS：似乎我没有空间发布index.hmtl（这只是一个正常的html）..

解决方案

你想访问根应用程序（http：// server：port /）但我是很确定Eclipse不会安装根应用程序。尝试在 http：// server：port / yourapp 下访问您在（eclipse托管）tomcat中部署的应用程序。

I got the same problem with the questions here : Tomcat started in eclipse but unable to connect to link to http://localhost:8085/, that means I can't open http://localhost:8080/ at the browser :

HTTP Status 404 - /
type Status report
message /

Apache Tomcat/7.0.27

I'm using Tomcat 7.0.27, Eclipse Europa and Java 1.6.0_32. I saw BalusC's answer, but the problem is that I couldn't select Tomcat installation (the picture below).

What could be wrong here?

EDIT1 : When I tried to create demo webpage, it couldn't be opened too (with the same error).

EDIT2: Followed this thread Why tomcat server location property is greyed in Eclipse I can open http://localhost:8080/ in the browser, but still cant access the demo web page..

    <welcome-file-list>
          <welcome-file> index.html</welcome-file>
    </welcome-file-list>
</web-app>

PS : It seems that there's no more space to me to post index.hmtl (it's just a normal html )..

解决方案

You want to access the root application (http://server:port/) but I'm quite sure that Eclipse wont install a root application. Try to access the application you deployed within the (eclipse managed) tomcat under http://server:port/yourapp.
