How to pass enviornment variables to jar file?

Question

I want to set run configuration option : Environment variable while running JAR and run it using java code. How to set environment option while running jar through java code?

Solution

ENV_VAR=some-value java -jar path/to/theJar.jar

You can then access that in Java via System.getEnv('ENV_VAR')

In java you can also do system properties

java -Dsome.system.prop=some-value -jar path/to/theJar.jar

you can then access the system props in code via System.getProperty('some.system.prop')
