SEVERE: The required Server component failed to start so Tomcat is unable to start. org.apache.catalina.LifecycleException: Failed to start component [StandardServer[8005]]
之前在Eclipse上部署了Tomcat服务器,今天在MyEclipse上部署,结果Tomcat启动失败,报错。在网上搜了半天,有的说是因为端口被占用,有的说因为Tomcat的JDK版本不对。其实都不是。原因是Tomcat的server.xml配置文件最后多出来的这几行,估计是以前在Eclipse上跑的项目自动生成的。把它们删了之后Tomcat就正常运行了。
