how to set tomcat JAVA_OPTS="-Djava.awt.headless=true" ????
which tomcat file to edit?... any sug???

You can create a file setenv.sh under tomcat/bin directory

The content of my setenv.sh is as follows:

JAVA_HOME="/usr/java/latest"

JAVA_OPTS="-server -XX:NewSize=123m -XX:MaxNewSize=123m -XX:SurvivorRatio=8 -Xss256k -Xms495m -Xmx495m -Djava.net.preferIPv4Stack=true -Djava.awt.headless=true"

You can modify the other memory size options according to your server's capacity.
