ubuntu로 Spring 프로젝트 배포 시 문제

Question

ubuntu 서버에 java-8-openjdk, tomcat9, oracle 11g XE 설치하구 Spring 프로젝트 war 파일을 FileZila로 업로드 했는데요404 not found 에러가 뜨네요context.xml에서 path&#61;&#34;/&#34; 설정해주라는 얘기가 있어서 해봤는데 해결 안됐고,tomcat 접근권한이 없어서 그렇다고도 하기에 sudo chown -R tomcat:tomcat /var/lib/tomcat9sudo chown -R tomcat:tomcat /etc/tomcat9sudo chown -R tomcat:tomcat /usr/share/tomcat9 이런것도 해봤는데 안되네요에러 로그는
