아름다운세상。

JavaEmail API 를 이용하기 위해서는 2개의 환경설정과 설치가 필요합니다.

1. JavaBeans Activation Framworks
http://java.sun.com/javase/technologies/desktop/javabeans/glasgow/jaf.html
2. JavaMail.
http://java.sun.com/products/javamail/index.jsp

다운로드가 완료된후 CLASSPATH를 설정합니다.;

;C:\javamail-1_4_1\javamail-1.4.1\mail.jar;C:\javamail-1_4_1\activation\activation.jar
이와 같이 자신의 경로에 맞게 추가 해줍니다.

/demo/폴더안에 보면 많은 예제들이 있습니다.;

우선 SMTP 서버가 있어야 합니다. naver.com 같은경우 으뜸회원이 되면 이용할수 있습니다.
