How do I use the JAVA_OPTS environment variable?

Question

How do I use the JAVA_OPTS variable to configure a web server (a linux server)?

How can I set -Djava.awt.headless=true using JAVA_OPT

Answer 1

JAVA_OPTS is not restricted to Tomcat’s Java process, but passed to all JVM processes running on the same machine.

Use CATALINA_OPTS if you specifically want to pass JVM arguments to Tomcat's servlet engine.
