Pass env var from java to c++

Question

Is there a way to set an environment variable or some kind of global variable in java so it can be visible from within the c++ code that I call from java (using swig). Off course as a workaround I can expose another function which will track the value of env var in some static variable in c++, so I can use it when it is needed. However it is interesting if there is a way to set env or global variable in java and make it visible in c++ code called from java.

There are ways to set environment variables in Java but they are not particularly nice, see this previously asked question .

I think your best bet would be to use JNI.
