1 Could not resolve XML resource [null] with public ID [null]

启动Tomcat报错： Java.io.FileNotFoundException: Could not resolve XML resource [null] with public ID [null], system ID [.

检查tomcat6.0.35没问题，高于6.0.35会报错。

解决办法：

tomcat 6.0.35或之前版本。2、把xmlBlockExterna设成false。 
下面是原版解释： 
As per discussion with Tomcat developers, xmlBlockExternal=”true” attribute of Tomcat’s Context (context.xml) was set true by default starting from 7.0.52. With xmlBlockExternal=”false”generated/djn-settings.conf can be included】 
- 修改Servers conf/context.xml

<Context  xmlBlockExternal="false">
