我的tomcat启动报错，情况是这样的：环境：系统：windows10java：java8tomcat: tomcat-8.0.28如果不做任何修改，tomcat启动正常，各个项目运行正常。为了编译方便（没有用IDE开发），我把从http://www.java2s.com/Code/Jar/j/Downloadjavaxservlet31jar.htm上下载的servlet-3.1.jar放到了%JAVA_HOME%\jre\lib\ext目录下编译倒是省事了，但启动tomcat就出错了，每个项目的报错都一样06-Dec-2015 17:38:43.004 SEVERE [localhost-startStop-1] org.apache.catalina.core.ContainerBase.addChildInternal ContainerBase.addChild: start: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/docs]] at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:154) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:725) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:701) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:717) ... 10 more06-Dec-2015 17:38:43.018 SEVERE [localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployDirectory Error deploying web application directory D:\tomcat\apache-tomcat-8.0.28\webapps\docs java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/docs]] at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:729) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:701) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:717) at org.apache.catalina.startup.HostConfig.deployDirectory(HostConfig.java:1101) at org.apache.catalina.startup.HostConfig$DeployDirectory.run(HostConfig.java:1816)06-Dec-2015 17:38:43.031 INFO [localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployDirectory Deployment of web application directory D:\tomcat\apache-tomcat-8.0.28\webapps\docs has finished in 488 ms

Caused by: java.lang.NoSuchMethodError: javax.servlet.ServletContext.getVirtualServerName()Ljava/lang/String;
估计jar包冲突了
