사진은 복붙한 코드입니다.
마지막 줄 tomcat.start()만 없으면, 에러는 안뜹니다.
LifecycleException 에러로 보이는데,,
https://www.inflearn.com/questions/5283/%EC%8B%AC%EA%B0%81-a-child-container-failed-during-start
유사한 에러가 이거 같은데, 봐도 기존 코드가 달라 해결법을 모르겠네요..

안녕하세요. 톨게이트님
내장 톰캣2 - 서블릿 마지막 부분을 보면 다음 내용이 추가되어 있는데요. 이 부분을 확인해주세요.
주의
실행시 특정 환경에서 다음과 같은 오류가 발생하는 경우가 있다.
Caused by: java.lang.IllegalArgumentException: The main resource set specified [...\tomcat\tomcat.8080\webapps] is not valid
이런 경우에는 다음을 참고해서 코드를 추가해주면 된다.
//서블릿 등록
Context context = tomcat.addContext("", "/");
//== 코드 추가 시작==
File docBaseFile = new File(context.getDocBase());
if (!docBaseFile.isAbsolute()) {
docBaseFile = new File(((org.apache.catalina.Host) context.getParent()).getAppBaseFile(), docBaseFile.getPath());
}
docBaseFile.mkdirs();
//== 코드 추가 종료==
tomcat.addServlet("", "helloServlet", new HelloServlet());
context.addServletMappingDecoded("/hello-servlet", "helloServlet");
tomcat.start();감사합니다.
