Host command not working properly

Question

Hi,
I am using oracle forms 10.1.2.0.2.
In my form, I need to call a unix shell script.
{ Oracle forms will run on application server.
Unix will run in a development server.
(Both the servers are different)
From forms, if I click a button, it should call the unix shell script in a specified path.
Internally, the unix script will call oracle to generate a file.
In the file, some manipulations are done using unix.
After doing some manipulations, the file is stored in a specified path in the unix box. }
To achieve the above, I did the below things.
To execute a unix shell script from my oracle forms (10g),
1) the below configuration i added in the webutil.cfg file
install.syslib.0.user.1=ffisamp.dll|40960|1.0|true
transfer.database.enabled=TRUE
transfer.appsrv.enabled=TRUE
transfer.appsrv.workAreaRoot=c:\temp
transfer.appsrv.accessControl=TRUE
#List transfer.appsrv.read.<n> directories
transfer.appsrv.read.1=c:\temp
#List transfer.appsrv.write.<n> directories
transfer.appsrv.write.1=c:\temp
2) I have attached webutil.pll library to my form
3) I have subclassed object group from webutil.olb to my form.
4) The host command i used is (these code are present in when-button-pressed trigger of a button)
host('rsh selvas -l administrator sh <foldername>/if_csv.ksh',NO_SCREEN);
if form_failure then
     emessage('hi selva');
emessage(SQLERRM);
else
     emessage('failure selva');
end if;     
when I click the button, I am getting the below messages,
hi selva
normal, successful completion
Also, the script is not executing and it is not giving me the desired result.
Can any one help me, where I am missing.
Thanks,
