Tomcat部署程序启动时问题：org.apache.catalina.session.StandardManager.doLoad

　　今天程序在Tomcat5.5.27下运行时，莫名其妙的在控制台出现以下错误：

　　从网络上查找的解决方案：
　　(1) Tomcat\work\Catalina\localhost\project\SESSIONS.sersession未超时的情况下服务器关闭大的时候被序列化为工程名\SESSIONS.ser启动的时候再加载进来，加载的时候报错了，把该文件删除，重新启动    补充：有时候不一定是SESSIONS.ser,我的那个下面就多了一个tldCache.ser,反正将里面以.ser结尾的都删除就是的。
　　(2)tomcat 启动的问题(org.apache.catalina.session.StandardManager.doLoad: IOException while loading persisted sessions) 大概是说tomcat上次关闭时还有一些活动连接，所以在重启时tomcat尝试去恢复这些session造成的。tomcat的work目录下面的东西删一遍。
