Cause of "Error deploying configuration descriptor" on Tomcat 7.0.12
提问by Dmitrii Pisarenko
When I try to deploy a WAR file by dropping it into webapps directory, I get following message in the console:
当我尝试通过将 WAR 文件放入 webapps 目录来部署它时，我在控制台中收到以下消息：
04.05.2011 19:34:07 org.apache.catalina.startup.HostConfig deployWAR
SEVERE: Error deploying configuration descriptor xyz.war
I didn't find any hints about the detailed cause of this in the logs.
我没有在日志中找到任何有关此问题的详细原因的提示。
Where can I find out the details (e. g. the stack trace) about this failure?
我在哪里可以找到有关此故障的详细信息（例如堆栈跟踪）？

I found the answer. The cause of the problem was a malformed context.xml file.
我找到了答案。问题的原因是格式错误的 context.xml 文件。
