当在linux服务器上没有装xwindows时, 处理图像时会报 java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable. 这个错. 解决方法: 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 " 就能解决问题.
