Out tomcat7无法启动。为了确定问题是tomcat本身还是我的代码，我从webapps文件夹中删除了除ROOT文件夹外的所有war文件。当我开始时，它未能抛出上述错误。Monocle是我删除的一场战争。我不明白为什么它还在试图找到Monocle。我已经从work文件夹中删除了Catalina文件夹。有人能帮我吗？我需要从任何其他位置清除缓存吗？
您可以验证TOMCAT_HOME/conf/server.xml文件
在标记中，appBase属性的默认值为wepapps，可能是您更改了appBase="/var/lib/tomcat7/webapps/Monocle"。
希望这能有所帮助！！！
ps：如果没有，请添加更多信息。例如：TOMCAT_HOME/conf/server.xml、TOMCAT_HHOME/conf/context.xml
