URGENT - runtime.exec command doesn't execute on unix

[parag chandekar]

The problem i am facing is that if I execute the command ./runpro ( name of my applications executable) from unix command prompt it is working ,also if i write the same command in a shell script it works on executing on the prompt with
sh shellscript.sh
where shellscript contains
./runpro

But if the same shell script is executed through the
Runtime.getRuntime().exec("sh","shellscript.sh") function of java it compiles and when it is run it displays nothing as if nothing has happened .
also directly executing the command through getRuntime().exec(" ./runpro") it is not working.
However if execute getRuntime().exec("ls") it works fine.

Is there any limitation on exec for executing executing users executable or user created .sh.

Pl reply asap

is your executable, "runpro", a graphical application or a text-mode one? are you running java in a graphical environment, like KDE or Gnome, or are you running it at the text-only console?

if it's a text-mode application and you're not running in text-only mode, you will likely have to provide a terminal for it to run in. try something like:

xterm -e ./runpro

and see if that works.

The executable, "runpro", is a text-mode application that counts the number of processes running and saves it in a log file .

and I am running java at the text-only console.

I tried your code but it is still not working. Do you have any other solution .Pls help
