尝试在我的 Eclipse 中配置 tomcat，但“本地主机上的 Tomcat v7.0 服务器所需的端口 8080 已在使用中。服务器可能已经在另一个进程中运行，或者系统进程可能正在使用该端口。要启动此服务器，您将需要停止其他进程或更改端口号”。我试图多次设置 tomcat 环境，但它给我带来了这个错误，我需要在 eclipse 中做任何事情吗？

In Serversview double-click on Tomcat and change HTTP port in Portssection to something else. Or in Package Explorernavigate to ServersTomcat and change Connectorport part inside server.xmlfile.

在Servers视图中双击 Tomcat 并将Ports部分中的HTTP 端口更改为其他内容。或者Package Explorer导航到ServersTomcat并更改文件中的Connector端口部分server.xml。

In eclipse->in server tap-> double click on Tomcat server at localhost-> Ports -> HTTP/1.1

在 eclipse->in server tap-> 双击 Tomcat 服务器 at localhost-> Ports -> HTTP/1.1

Default port number will be 8080. Change this to 8081. Tomcat version7.0

默认端口号为 8080。将其更改为 8081。Tomcat version7.0

I have configured tomcat server also in NetBeans IDE 7.4 for JSP. So am facing this issue.

Method 1:

• uninstall that program

• 键入localhost:8080您的浏览器知道哪个进程占用8080端口
• 卸载那个程序

Method 2:

方法二：

re-install the apache tomcat BUT during installation change the port number. Watch carefully the installation process

I was having the same problem when my workspace was in E:\ drive. Then I changed my workspace location to C:\User\\ location. The problem seems to be solved now.

当我的工作区位于 E:\ 驱动器时，我遇到了同样的问题。然后我将我的工作区位置更改为 C:\User\\ 位置。现在问题似乎已经解决了。

Hey i got the solution recently... Just copy the "ROOT" folder FROM C:\Program Files\ Apache Software Foundation\ Tomcat 7.0\ webapps \ TO your_Workspace\ .metadata\ .plugins\ org.eclipse.wst.server.core\ tmp0 \wtpwebapps\ and over write it when asked..

嘿，我最近得到了解决方案......只需从 C:\Program Files\ Apache Software Foundation\ Tomcat 7.0\ webapps \ TO your_Workspace\ .metadata\ .plugins\ org.eclipse.wst.server.core 复制“ROOT”文件夹\ tmp0 \wtpwebapps\ 并在询问时覆盖它..

This is needed because eclipse forgets to copy that root folder to its workspace.. Just right click on Apache tomcat 7.0 in servers tab and observe that in location will be workspace metadata by default example:"location:[workspace metadata]". Therefore it will find the root folder which has the welcome page in it and the 404 page not found error will be displayed. Thankyou ..

这是必需的，因为 eclipse 忘记将该根文件夹复制到其工作区。只需右键单击服务器选项卡中的 Apache tomcat 7.0 并观察默认情况下，位置将是工作区元数据，例如：“位置：[工作区元数据]”。因此，它将找到其中包含欢迎页面的根文件夹，并会显示 404 页面未找到错误。谢谢 ..
