Hello Upul,
Thanks for your reply. Actually this will work and I have already
thought about it; the problem I found with this solution is that the
deletion of the file (in the server side) is after an acknowledgment FROM
the client. this ACK could be easily bypassed: I mean, no one is obliging
people using my service to develop a client that acknowledges receipt of the
file !!! hence making it possible for the file to reside on the server. For
your concern about if the file is lost, this is not a problem because the
file the server sends to a client is an encryption of a file sent from
Client to Server, hence if there is any problem (which is very very very
rare since Axis2 over TCP is almost error free I guess), the client will
just re-request the encryption of his file. So, I am really looking for a
thing that tells me that the last byte has been sent to the client.
Thanks again,
Elmouj,
