Maximo Open Forum

Hi All,
I m trying to download one text file from remote server to maximo application server using pysftp. So here i installed the pysftp library in my local machine and copied the installed files to the additional libraries section. 
I configured the system properties which has the location of this pysftp library and referred this system properties in the autoscript script and used import pysftp in the code to refer the library and this autoscript is executed via cron task application. But still getting error no module found : Pysftp. 
Has someone come across similar issue please do let me know. Or is there any alternate way to download the file via maximo.

Note: The similar code when i executed via python Idle it works fine.
