提问by Eyosiyas Tadele
I have been working on xampp tomcat server and I'm new for it. I configured it and starts the xampp tomcat. It works fine and I see all the ports I configured perfectly but after 3 minutes it shows me this error
我一直在研究 xampp tomcat 服务器，我是新手。我配置了它并启动了xampp tomcat。它工作正常，我看到我完美配置的所有端口，但 3 分钟后它显示了这个错误

See :
看 ：
Caused by: java.net.BindException: Address already in use: JVM_Bind
The port that Tomcat is configured to use, is already in use by another application.
Tomcat 配置使用的端口已被另一个应用程序使用。
Either shutdown the other application, or edit your server.xmlfile to use another port (the default one is 8080).
关闭另一个应用程序，或编辑您的server.xml文件以使用另一个端口（默认端口为 8080）。

This is the cause:
这是原因：
Caused by: java.net.BindException: Address already in use: JVM_Bind :8080
引起：java.net.BindException：地址已在使用：JVM_Bind :8080
It means the server is trying to bind to port 8080but your machine already has something bound there. Make sure one of your other processes isn't taking up that port, or select another one (probably in server.xml) to use.
这意味着服务器正在尝试绑定到端口，8080但您的机器已经绑定了一些东西。确保您的其他进程之一未占用该端口，或选择另一个进程（可能在 中server.xml）使用。
