Tomcat启动时如下错误：
严重: IOException while loading persisted sessions: java.io.EOFException java.io.EOFException at java.io.ObjectInputStream$PeekInputStream.readFully(ObjectInputStream.java:2280) at java.io.ObjectInputStream$BlockDataInputStream.readShort(ObjectInputStream.java:2749) at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:779) at java.io.ObjectInputStream.<init>(ObjectInputStream.java:279) at org.apache.catalina.util.CustomObjectInputStream.<init>(CustomObjectInputStream.java:58) at org.apache.catalina.session.StandardManager.doLoad(StandardManager.java:362) at org.apache.catalina.session.StandardManager.load(StandardManager.java:321) at org.apache.catalina.session.StandardManager.start(StandardManager.java:637) at org.apache.catalina.core.ContainerBase.setManager(ContainerBase.java:433) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4257) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:761) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:741) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:525) at org.apache.catalina.startup.HostConfig.deployDirectory(HostConfig.java:920) at org.apache.catalina.startup.HostConfig.deployDirectories(HostConfig.java:883) at org.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:492) at org.apache.catalina.startup.HostConfig.start(HostConfig.java:1138) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:311) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:120) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1023) at org.apache.catalina.core.StandardHost.start(StandardHost.java:719) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1015) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:443) at org.apache.catalina.core.StandardService.start(StandardService.java:448) at org.apache.catalina.core.StandardServer.start(StandardServer.java:710) at org.apache.catalina.startup.Catalina.start(Catalina.java:552) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:288) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413)
原因： EOFException表示输入过程中意外地到达文件尾或流尾的信号,导致从 session中获取数据失败。异常是tomcat本身的问题，由于tomcat上次非正常关闭时有一些活动session被持久化（表现为一些临时文 件），在重启时，tomcat尝试去恢复这些session的持久化数据但又读取失败造成的。此异常不影响系统的使用。 解决办法： 将Tomcat 6.0\work下的文件清空，主要是*.ser文件，或者只是删除掉session.ser，重启tomcat，即可以解决。
