    分析：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:在tomcat6.0\work\Catalina\localhost下搜索“.ser”，删除这个文件。如果正常关闭服务端，该文件是自动删除的。

        我参照上面方法解决的问题，用的是MyEclipse7.0,tomcat6.0。通常情况下，会认为是tomcat的缓存，会直接把整个localhost文件夹删除。但是上面的方法也是可取的，在localhost文件夹下，找到部署的工程名，在该工程名下有SESSIONS.ser文件，直接删除。重启tomcat，问题解决。

或者：
   (tomcat_home)\work\Catalina\localhost\tldCache.ser，有可能是SESSION.ser，删除这个文件就行
