本文介绍了在Eclipse中启动Tomcat遇到的两种常见错误：文档基不存在或不可读的目录，详细解释了错误原因并提供了实用的解决方案。

概述：

突然异常拦住我了。

用eclipse启动tomcat应用发现报错了，这时候简单粗暴的方法，在标签Servers页面，删除tomcat，然后再添加Tomcat就好了。一般罪魁祸首就是server.xml的Context标签，你可以先移除Context标签的内容，再次启动tomcat，实在不能解决办法就是删（慎重操作，记得备份、备份、备份、eclipse对于tomcat配置文件）

异常二：

看异常发现它去找context文件，纳闷，其实tomcat说了配置文件隔离，只是说context.xml(就是上下文)文件配置内容隔离，并不是所有配置，而且这个配置文件为你应用名，

例如tomcat 有manager应用，那么这个配置文件可以写成复制context.xml到CATALINA_HOME/conf/[EngineName]/
[Hostname]/ 目录下改名为manager.xml 即可

EngineName（引擎名）：Catalina Hostname(主机名)：localhost
