Runtime.exec() in jar

Hi i wanted to exec an aplication in my aplication. My aplication is in jar file. When i run my aplication by duble-click (no command box is showed) Runtime.exec() doesn't work (gives IOException Creating Process anotheraplicationpath error=5), but when i run it from cmd and command box isn't hided it works. When I run it in eclipse(command box is shown) it works too, but I must do that so that command box won't be shown

My OS is Win XP professional, i use JRE 1.5 Update 6

PS. Sorry for my bad English
