java - Specifying JVM arguments when calling a jar file?

Question

I want to specify some JVM arguments when calling a jar file like so:

java -jar filename.jar

I assumed I did it like so:

java -Xms256m -Xmx512m -Djava.awt.headless=true jar filename.jar

But this doesn't seem to work. What am I doing wrong?

Answer 1

Do it like:

java -Xms256m -Xmx512m -Djava.awt.headless=true -jar filename.jar
