今天遇到了这个错误，导致TOMCAT不能正常启动
四月 12, 2012 1:11:18 上午 org.apache.catalina.core.ContainerBase startInternal
严重: A child container failed during start
java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/myWebSite]]
at java.util.concurrent.FutureTask$Sync.innerGet(FutureTask.java:252)
..........
仔细检查后发现原来是web.xml里面Servlet路径设置出错（一个Servlet的路径没加上"/"）
