tomcat正常启动没有问题，重新部署项目就报这异常,困了我好久了，到底是哪里引起的？
向大神们取取经！
tomcat 异常 重新部署 java
------解决方案--------------------
打开tomcat的目录里的bin文件夹,运行里面的shutdown.bat。
启动用startup.bar
不要直接关闭窗口
------解决方案--------------------
楼主用的 eclipse 自带的插件吧？
用这个吧：
集成 Tomcat 插件到 Eclipse 的过程
免部署、启动/重启/关闭很便捷
支持断点跟踪调试
------解决方案--------------------
还有一种可能就是你这个项目没错 但是以前部署的项目有问题就一起爆出来了
比如你启动tomcat 里面的 program1 时候 program2的错误也会显示
------解决方案--------------------
试下1楼的清空下。
