테스트 프로그램을 구현하다가 웹이 아닌 그냥 자바 클래스를 실행해야 하는 경우가 생겼다.

그런데 -classpath옵션이 windowunix를 틀린것을 발견했다. 웹프로그래밍만 하다 보니 이제껏 이걸 모르고 있었다는게 한심하다.

다른점은 구분자(semi-colon과 그냥 colon)의 차이점이다.

예를 들면 다음과 같다.

window

java -cp .;..\lib\mail.jar;..\lib\activation.jar mail.MailSender


unix

java -cp .:../lib/mail.jar:../lib/activation.jar mail.MailSender


java help를 보니.. 다음과 같이 정확하게 구분자가 나와 있었다.

window
