Enumerate H/W Devices on win32

[Ben Cartwright]

Hello,

Is there a way, using Java, to determine and to enumerate the hardware devices
installed on a win32 machine?

Thanks,
Ben

Only through some pretty black JNI magic, I reckon...

Is there a COM mechanism to do this, perhaps?

Well you could ask the registry for the keys under
"HKLM\Software\Javasoft\Java Runtime Environment"

If you don't want to dive into JNI, but are OK with COM, then you should be
able to get the info you need via "Windows Management Instrumentation" (which
is COM based).

For an intro see:

and specially:

But be aware that:

a) it's not installed by default on Window's boxes before WinXP, which may
limit it's use for you.
b) it's pretty general, hence complicated.
