how can my java code read OS environment variables?

hi,

this may be a very simple problem, but I couldn't find an answer googleing and I'm in a rush - so I'd appreciate fast code examples.

I have an environment variable on the OS i would like to read using java code. I've tried System.getProperty, but that only seems to work for the -D variables supplied directly for the JVM.

how can my java code read OS variables?

+14  A: 

Try System.getenv(String name)

Although if you are still using 1.4 (which has end of lifed, but there's still paid support available), it will throw an Error.
