java, xml 수정 할때마다 톰캣을 재기동했던 경험.
누구나 있을 것이다.
Hotswap 기능이 간절 하다.
그래서 많이 쓰던게 jRebel 인데 2018년 7월부터 유료화가되었다.
값이 1년에 2,3만원 이면 결제 하겠는데
가격이 너무 비싸서 방법을 찾던중 오픈소스 기반의 DCEVM 를
알게 되었다.
DCEVM 설치 방법은 인터넷 검색해 보면 많이 나오니
검색해 보시길.
그런데 내가 처음 설정 할땐 에러가 나서 삽질 좀 했다.
해서 내가 해결한 방법을 공유 하려고 한다.
에러내용은 아래와 같다.

해결 방법은 jdk 버젼 문제다.
내가 설치한 버젼은 jdk1.7.0_80 인데 구글을 아주 열심히 찾아 보니
버젼 문제로 보여 jdk1.7.0_67 로 낮추니 해결 되었다.
이노무 jdk 버젼 문제...
다른 사람은 나처럼 삽질 안하길...
