Hi Ally,

Ofcourse I configured the security properly and I when I use the
synchronous and asynchronous mode of data retrievel I did not face any
problems with that. In my previous mail, I attached my code (here its
again). From that you can see that I set the securtiy properly. I am
pretty sure it has nothing to do with that because I could transfer the
results using normal ftp, but for GridFTP its reporting the missed
credential. Like I mentioned in my last mail, I could not figure out
where and how the "mContext" is defined in
DeliverFromGFTActivity.javaregards. Exactly at this place the exception
thrown.

regards,
Samatha
