Re: [Jython-users] os.environ not implemented?

[brian z. <bz...@zi...>]

It's not implemented in Jython because the JVM does not provide access to the environment.  You'd have to write JNI code to get such a facility (I think Finn wrote such a module once).  The closest you get is System.getProperties(), which is not really the same thing.
