调用 jar 文件时指定 JVM arguments？

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

Answer 2

java [Options] -jar  [jarfile] [Command Line Arguments]

Please refer

Answer 3

hype jar was missing, try

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

Answer 4

Don't put a space between the -D and java.awt.headless=true.

It should be -Djava.awt.headless=true.
