Error while downloading zip file using commons-net 1.4.1

[s n]

Hi All,

I am trying to use the commons-net (1.4.1) package to download zip files from 
and FTP site.Everything seems to be working fine (Able to login and download 
the file), except when i try to open the downloaded zip file.

I am not sure why this happens. Any help would be highly appreciated.

I have pasted the error and my code below:

Thanks!



I get the following error (winzip spits out this error)
