Run exe which is packaged inside jar file

I am executing an exe through my java program. The path is hardcoded in Java.

I have packaged my the exe in the jar.

But am stuck as I have the path name hardcoded in the Java file, so I am not able to execute my jar as a stand alone program.

Any hints for packaging such jar i.e having an exe inside and able to run it as a stand alone program?
