java.lang.IllegalArgumentException: Document base tomcat\webapps\appdata does not exist or is not a readable directory
提问by IAmYourFaja
I had a WAR previously deployed on my local Tomcat (6.0.35) instance called appdata.war, and so the webapps directory looked like:
我之前在本地 Tomcat (6.0.35) 实例上部署了一个名为 的 WAR appdata.war，因此 webapps 目录如下所示：
webapps/
docs/
examples/
host-manager/
manager/
appdata/ (exploded WAR)
ROOT/
appdata.war
I deleted appdata/and appdata.war(so that Tomcat wouldn't try to redeploy it) and then added a new war (appmon-qa.war) to this directory. I then ran the Tomcat startup script and saw deployment errors referencing the "old" appdataWAR. I poked around and saw a folder with that name located at ${TOMCAT.HOME}/work/Catalina/localhost/appdataand I deleted it (again, just to prevent Tomcat from re-deploying it). I then re-ran the startup scripts and am seeing this in the catalina log:
我删除了appdata/and appdata.war（这样 Tomcat 就不会尝试重新部署它），然后向该appmon-qa.war目录添加了一个新的 war ( )。然后我运行了 Tomcat 启动脚本，看到了引用“旧” appdataWAR 的部署错误。我四处张望，看到一个名为 的文件夹，${TOMCAT.HOME}/work/Catalina/localhost/appdata我将其删除（再次，只是为了防止 Tomcat 重新部署它）。然后我重新运行了启动脚本，并在 catalina 日志中看到了这一点：

I assumethat my oh-so-perfectly-written appmon-qa.warapp is failing to deploy because of some ghost reference to this old appdata.warapp. If so, do I (properly) undeploy or delete it from Tomcat altogether so that it doesn't cause problems for my new app?
我假设我写的如此完美的appmon-qa.war应用程序无法部署，因为对这个旧appdata.war应用程序有一些幽灵引用。如果是这样，我是否（正确）从 Tomcat 中完全取消部署或删除它，以便它不会对我的新应用程序造成问题？
Otherwise, if this log output indicates that there is something wrong with appmon-qa.waritself, then where do I start debugging? Usually these "failed due to previous errors" output also includes a reason or source of what the errors are; this output is pretty undescriptive and vague. Thanks in advance!
否则，如果这个日志输出表明appmon-qa.war本身有问题，那么我从哪里开始调试？通常这些“由于先前的错误而失败”的输出还包括错误的原因或来源；此输出非常不具描述性且含糊不清。提前致谢！

Take a look at ${TOMCAT.HOME}/conf/Catalina/localhost/appdata.xmland delete it if it exists.
查看${TOMCAT.HOME}/conf/Catalina/localhost/appdata.xml并删除它，如果它存在。

I had this same error (Document base ... does not exist or is not a readable directory). The easy solution was to re-install Tomcat over the existing one (ignore the warning "cannot install service" because it is already there).
我有同样的错误（文档库...不存在或不是可读目录）。简单的解决方案是在现有的 Tomcat 上重新安装 Tomcat（忽略警告“无法安装服务”，因为它已经存在）。
