미해결자바 스프링 프레임워크(renew ver.) - 신입 프로그래머를 위한 강좌
안녕하세요 질문있습니다.
The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application오류가 이렇게 나는데..jstl jar파일이 없기 때문에 오류가 난다고 생각하는데요.강사님은 다른 작업 없이 잘되는데, 제가 강사님 따라서 실행하면 이런 오류가 떠서 jar 파일을 web-inf아래 lib 폴더 안에 넣어주면 잘 실행 되는데요, 폴더에 안 넣어주고 바로 실행 해도 잘 되는 비법이 뭔가여

처음 해보는 스프링 프로젝트 중 pom.xml
컨테이너생성시에 import가 안되서 pom.xml의 modelVersion, dependency>version을 스프링 버전인 5.0.0으로 바꾸니까 되네요. 맞게한건가요?두개의 버전이 어떤 버전을 뜻하는지 궁금하구요.그리고, build>version은 어떤 버전을 뜻하는지 궁금합니다.
