Tiles 인터넷 연결 안될때 dtd 못 불러오는 문제 문의

Question

열심히 구글링 한 결과 답을 찾지 못해서 질문 남깁니다.일반적인 상황에서는 잘 되는데 인터넷을 끊고, 나서 페이지를 접속하려고 하면아래와 같은 에러가 발생합니다..1월 13, 2018 6:14:08 오후 org.apache.catalina.core.StandardWrapperValve invoke 심각: Servlet.service() for servlet

없을까요?

먹자 · Accepted Answer

자문자답입니다. 이 부분을 아래와 같이 버전을 바꿔주면 인터넷이 연결되지 않는 환경이라도 정상적으로 tiles가 동작합니다. 3.0버전은 로컬에 있는 dtd파일을 우선적으로 찾고, 없을 경우 기재된 url을 통해서 가져오는 방식인 건 것같은데 2.1버전은 로컬에 있는 dtd파일을 가져오는 로직이 없는 것이 아닌가 하는 예상입니다.
