Using System.getenv()

Hi all,

I have set some environment variables in my unix OS and would like to retrieve them in windows OS. Can I use System.getenv("env var") in my java code running in Windows to do this?

Or, is there any other way of obtaining the same?

Thanks!!

The question doesn't seem to make sense: of course you can't read Unix environment variables on Windows.

If you mean "does getenv() work on Windows?", the answer is yes. Though it went through a period of being deprecated, it is now a proper interface again in the latest Java.

Hi,

Welcome to JavaRanch!

First, a bit of business: you may not have read our naming policy on the way in. It requires that you use a full, real (sounding) first and last name for your display name, with a space in between. You can change your display name here. Thanks!

I have had trouble with the environmental variables in UNIX when accessing them through Java (i.e. using exec, or getenv). I found that java doesnt correctly read my environmental variables ! For example, a quick "echo $PATH" yields a string with 5 path values in it (/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/:/usr/local/bin/MyPrograms) but in java, my "Path" as displayed using process.exec has only 3 entries (/bin:/sbin:/usr/bin:/usr/sbin).

Is there a way to force java to obtain the "Path" using the same method that my "shells" use ? I've never really thought about the shells and where they get their environmental variables from, but it seems like they always seem to work !

hi jay,
i don't think java is not able to read env variables properly. i just tried the same thing and got the following result

C:\ClarifyCRM12iSR1.04\Configurator\Common Files\CCAutomation;C:\ClarifyCRM12iSR
1.04\ClarifyClient;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\Pr
ogram Files\Java\jdk1.5.0_07\bin

using System.getenv("PATH")

which is exactly same as what i get with echo command.

there may be some other scenario in which you are getting this problem.

Hmmm... do you think it is UNIX related ? Are there different PATH's for different processes in UNIX ?
