How should I `java -jar a.jar`, then exit java but keep jar

Question

I want to run jar runnable file on windows. In cmd, I type java -jar a.jar, but it will start a java exe first for a.jar's parent, but I don't want it.(or start java and start a.jar, then exit java but keep jar) If I only type a.jar in cmd, it work well, but for some reason, I must start it from java, How should I do?
