MS(Managed Server) 내의 웹 엔진(서블릿 엔진)에 적어도 1개의 웹 커넥션이 설정되어 있어야 한다. 웹 커넥션 설정은 “제2장 웹 커넥션 관리”를 참고한다.

간단하게 “2.3.3. HTTP 리스너 설정”에서와 같이 포트가 '8088'로 설정된 동일한 HTTP 리스너를 추가하여 간단하게 실행해 볼 수 있다.

설정이 완료되면 콘솔 화면을 실행하고 다음과 같이 명령을 입력하면 JEUS Launcher가 실행된다. 여기서 -u와 -p는 JEUS를 설치할 때 설정한 관리자 이름과 패스워드를 의미한다.

아래 예제에서는 관리자 이름과 패스워드를 'jeus'로 설정했다고 가정한다.

startMasterServer -domain domain1 -server server1 -u jeus -p jeus

다른 콘솔 화면을 열고, 이번에는 'jeusadmin -u jeus -p jeus' 명령을 실행한다(여기서 -u, -p를 입력하지 않았다면 다시 한 번 'login -u jeus -p jeus'을 입력하여 로그인 할 수 있다).

$ jeusadmin
JEUS 21 Administration Tool
To view help, use the 'help' command.

Attempting to connect to 127.0.0.1:9736.
The connection has been established to JEUS Master Server [adminServer] in the domain [domain1].

다음과 같이 명령을 실행하면 웹 엔진을 모니터링하고 제어할 수 있는 명령어들의 목록이 출력된다.

웹 엔진 제어 명령어나 모니터링 명령어를 수행한다. 웹 엔진 명령어는 “JEUS Reference 안내서”의 “4.2.8. 웹 엔진 관련 명령어”를 참고한다.

WebAdmin에서도 위와 동일한 작업을 수행할 수 있다. WebAdmin에서의 수행 방법에 대한 자세한 내용은 JEUS 21을 참고한다.
