java.lang.IllegalArgumentException: Document base dir does not exist or is not a readable directory
提问by majji
I have seen the same kind of questions in stackoverflow but those questions were not helping me. I wanted to run my app from outside of Tomcat, so I have used "Context" of Tomcat.
In the context I have given the docBaselike below.
我在 stackoverflow 中看到过类似的问题，但这些问题对我没有帮助。我想从 Tomcat 外部运行我的应用程序，所以我使用了 Tomcat 的“上下文”。在上下文中，我给出了docBase以下内容。
<Context docBase="../IdP/IdPserver/idp" // which is relative path
privileged="true"
antiResourceLocking="false"
antiJARLocking="false"
unpackWAR="false" />
The actual location(absolute path) is D://SRDM2.3/srdm/svr//IdP/IdPserver/idp. But it was not working with relative path but is working with absolute path.
I got the following error while using relative path.
实际位置（绝对路径）是D://SRDM2.3/srdm/svr//IdP/IdPserver/idp。但它不适用于相对路径，而是使用绝对路径。使用相对路径时出现以下错误。

Do you think the actual:
你认为实际：
D://SRDM2.3/srdm/svr//IdP/IdPserver/idp
is the same as the missing?
和失踪一样吗？
D:\SDC-Builds\SRDM2.3.0.6904.10\SRDM\Svr\tomcat\webapps\..\IdP\IdPserver\idp
Resolving the ..in the second one results in
解决..第二个结果中的
D:\SDC-Builds\SRDM2.3.0.6904.10\SRDM\Svr\tomcat\IdP\IdPserver\idp
You sill need another .., so try this one:
你还需要另一个..，所以试试这个：
<Context docBase="../../IdP/IdPserver/idp"
