Hi Naveen,

it has been some time since I used this feature but there is a patch
originally by Adobe to support this which I once adapted to work with
JCIFS 1.3.14.
Maybe you'll have to make some more changes to get it to patch a
current version, but you should give it a try.
You can find it here:

Best regards
