Could not resolve XML resource [null] with public ID [null], system ID …………
tomcat 7.0.52开始的版本才会出这个问题,是因为安全的考虑tomcat 7.0.52开始的版本把 context.xml 中的xmlBlockExterna属性默认为false,要解决这个问题,两种方法:1、把tomcat版本换成7.0.52之前的版本。2、把xmlBlockExterna设成true。
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
apache-tomcat-7.0.64\conf\context.xml修改后的配置:

There is not only one validationQuery for all databases. On each database you have to use different validationQuery.
After few hours of googling and testing I have collected this table:
Database validationQuery notes
hsqldb - select 1 from INFORMATION_SCHEMA.SYSTEM_USERS
Oracle - select 1 from dual
DB2 - select 1 from sysibm.sysdummy1
mysql - select 1
microsoft SQL Server - select 1 (tested on SQL-Server 9.0, 10.5 [2008])
postgresql - select 1
ingres - select 1
derby - values 1
H2 - select 1
Firebird - select 1 from rdb$database
-->
