當(dāng)在linux服務(wù)器上沒有裝xwindows時(shí), 處理圖像時(shí)會(huì)報(bào)
java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.
這個(gè)錯(cuò).
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.
