當在linux服務器上沒有裝xwindows時, 處理圖像時會報
java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.
這個錯.
解決方法:
在tomcat的catalina.sh文件中
找到
# ----- Execute The Requested Command -----------------------------------------
echo "Using CATALINA_BASE: $CATALINA_BASE"
echo "Using CATALINA_HOME: $CATALINA_HOME"
echo "Using CATALINA_TMPDIR: $CATALINA_TMPDIR"
echo "Using JAVA_HOME: $JAVA_HOME"
加入
JAVA_OPTS="-Djava.awt.headless=true "
就能解決問題.
