java.lang.NoClassDefFoundError: Could not initialize class sun.awt.X11GraphicsEnvironment in linux

리눅스 서버에서 톰캣을 깔고 이클립스에서 작성한 프로젝트를 올려서 사용하던 중에

java.lang.NoClassDefFoundError: Could not initialize class sun.awt.X11GraphicsEnvironment 이런 에러가 났다.

어.. 로컬에서 테스트를 했을 때는 이상이 없는데

서버에 올린 후 테스트를 하면... 작동이 되지 않았다.. 

/usr/local/apache-tomcat-7.0.69/logs/localhost.2016-10-13.log 에서 에러를 발견했는데

이곳에 해결방법이 있었다

Try running this code in a constructor of a servlet System.setProperty("java.awt.headless", "true"); or Use this parameter in the startup script of the server: -Djava.awt.headless=true

I tried configuring JAVA_OPTS with -Djava.awt.headless=true but it doesn't work!

Any has other solution to the issue?

Try running this code in a constructor of a servlet System.setProperty("java.awt.headless", "true"); or Use this parameter in the startup script of the server: -Djava.awt.headless=true

-Djava.awt.headless=true 이걸 

/usr/local/apache-tomcat-7.0.69_openCRX/bin/catalina.sh 이 파일에

JAVA_OPTS="$JAVA_OPTS $JSSE_OPTS -Djava.awt.headless=true" 이렇게 붙여넣는다

나는 231번째 줄에 있었고

if [ -z "$JSSE_OPTS" ] ; then

  JSSE_OPTS="-Djdk.tls.ephemeralDHKeySize=2048"

fi

JAVA_OPTS="$JAVA_OPTS $JSSE_OPTS"

기존에 이렇게 되어 있던 것에서 =====>

if [ -z "$JSSE_OPTS" ] ; then

  JSSE_OPTS="-Djdk.tls.ephemeralDHKeySize=2048"

fi

JAVA_OPTS="$JAVA_OPTS $JSSE_OPTS -Djava.awt.headless=true"

이렇게 변경하였다.
