해결 : 아래와 같이 해결
java 1.4 버전 이상에서는 자바 자체에서 처리 가능하게 할수 있습니다.
리눅스에서 굳이 x-window나 xvf 깔기 귀찮다고 아니면 할줄 모르시는 분들은 간단하게 이문제를 해결하는 방법이 있습니다.
<!--
Note: If true, the system property, java.awt.headless, will be set to true.
This should be used with JDK 1.4+ on servers without graphics cards and
monitors. Otherwise, the property is not set.
-->
<!-- <headless-server>true</headless-server> -->
/WEB-INF/flex/flex-config.xml에서 이부분의 주석을 제거 해주시면 됩니다.
<headless-server>true</headless-server>
그리고 자바 구동시에(톰켓이나 레진) JVM 파라메터를 적는 부분이 있을 것입니다.
레진 같은 경우 걍 뒤에 자바 파라메터 적으면 작동됩니다.
resin start -Djava.awt.headless=true
즉 flex-config에서 headless-server 수정하고 jsp 엔진 구동시에 파라 메터 Djava.awt.headless=true 를 넣어주면 에러없이 잘 해결된다.
톰캣에서 이용할때는 catalina.sh 파일에
CATALINA_OPTS=-Djava.awt.headless=true를 추가하고 재구동하면 된다.
