Getting the value of an environment variable in java?

I set the environment variable in windows named "sample". Can I get this environment variable value using the code below?

System.getProperty("sample");

in a UAT environment I have a LINUX OS. Can I set the same environment variable in LINUX and get it with System.getProperty("sample")?

I mean, what System.getProperty("sample");is retrieved regardless of the operating system?

Also, I would like to get the value of the environment variable in JSP. I know that it is not recommended to save the logic in jsp, but still I need to use it. Can i use System.getProperty("sample");in jsp? Please help me.
