tomcat8 resource설정

매니저 화면이 아닌 xml에서 관리 하는 경우

tomcat8 에서 jndi설정을 하는 경우 기존 tomcat과는 설정 위치가 다르기 때문에 

관련 내용을 정리한 url은 아래와 같습니다.

https://tomcat.apache.org/tomcat-8.0-doc/jndi-datasource-examples-howto.html

server.xml에 등록되던 내용이 

context.xml 으로 이동하게 됩니다. resource 설정을 /tomcat/conf/context.xml에 등록하고 

해당  resource에 대한 사용 설정을 설치된 webapp의 /WEB-INF/web.xml에 등록 하는 구조로 변경 되었습니다.
