Error: Unable To Access Jar File
this guy had the same problem, unfortunately i did not completely understood where did he move his .jar file. Mine is on desktop and i get unable to access on "cmd" aswell.
I created my .jar same way - exported from Eclipse, to desktop.
I'm answering my own question, since i found a problem to my solution, got it by lucky and it may be help for others aswell, since the internet did not quite exactly knew what i was doing wrong.
So the idea where to move it is in your project's folder. Simple as that. After moving there, it worked like a charm :).
