[Guenther Koegel <guenther.koegel@xxxxxxxxx>]

Dear Joneo,

environment variables are local to your process. Starting a new process 
will create a *copy* of your environment variables and whatever the new 
process does, e.g. your batch file, does not affect your own environment.

The solution is quite simple. Your call to "java.lang.Runtime.exe" 
method comes in different flavours: Some have a String array where *you* 
provide all the environment variables for the new process. Here is the 
point to add your new environment variable "abc=whatever".

Bye,

Guünther
