Execute Shell Script from Flex for mac os

Question

I am dealing here with NativeProcess and specificly with commands in mac os.So, i have a .sh file in same directory as my application.By this shell script i am trying to execute a .jarfile (same directory as well). Somehow i am doing some mistake thats why it didn't work.

my code is next

There is not much to walk on when working with NativeProcesses.if you see anything wierd or wrong,please let me know.

Thank you
