tomcat下么有任何工程，也是这样，试过6.0.35、6.0.20两个版本，求解？？？？？？？？？？

------解决方案--------------------
确实有点神奇，看看logs/下有没有别的日志
------解决方案--------------------
ls -a apache-tomcat-6.0.20/logs/

只要今天有更新长度不为0的日志都cat一下看看
------解决方案--------------------
LZ改过配置文件了？找一份最原始的启动看看，再确认一下JDK环境变量有没有设置正确。
------解决方案--------------------
看看你jdk安装好没 环境变量设置好了吗
配置文件有错误没
