Subject headless mode in tomcat
Date Wed, 03 Aug 2016 08:50:47 GMT
Hi all,
    I've add the following line to setenv.sh in tomcat bin directory.

    export CATALINA_OPTS="$CATALINA_OPTS  -Djava.awt.headless=true"

    I have some image processing code in spring bean which runs well at the
first time.
After some time,let me say 1 or 2 days, exception ocurrs.  Any clue would
be appreciated.
