Hi folk!
I have written a Instant Messing application base on xmpp protocol use ECF, and I have implemented registeer,login,roster managent(add,delete),and one-to-one chat,when I want to use the filetransfer in the ECF to implements file transfer function, no matter how did I try,one send request,but the other have no response, the server I use is Openfire 3.3.0,it support xmpp file transfer specification XEP-0096,are they compatible?
There are two Adapter in the filetransfer partition: IOutgoingFileTransferContainerAdapter and IRetrieveFileTransferContainerAdapter, I just want to send and receive, do I have to use the second one? and the process? thanks!

They should be.
See below...I think the problem might be a simple matter of registering
a listener. If the below doesn't fix things then see **.

No, if you are using the peer-initiated file transfer then its only
necessary to use the IOutgoingFileTransferContainerAdapter. But in
order to *receive* requests (on all potential receivers) you have to
On (potential) receiver(s):
1) Get an IOutgoingFileTransferContainerAdapter.
2) Call
IOutgoingFileTransferContainerAdapter.addListener(IIncomingF ileTransferRequestListener
yourListener)
On sender:
1) Get an IOutgoingFileTransferContainerAdapter.
2) Call IOutgoingFileTransferContainerAdapter.sendOutgoingRequest(.. .)
On the receiver, the
IIncomingFileTransferRequestListener.handleFileTransferReque st(...) will
be called, and you can do what you need/want to do with the request
(refuse it, accept, etc).
So I think the problem might be that you are *not* be calling the
addListener method on the receivers...and therefore when you send a
request no one is listening :). Is this the problem? If not, then see
below.
Just to summarize
Sender Receiver(s)
Calls addListener(rl)
Calls sendOutgoingRequest -> rl.handleFileTransferRequest
handleTransferEvent <- r1.accept/reject
If you want example code that does this, see (in the
/cvsroot/technology/org.eclipse.ecf/tests CVS module), in the
org.eclipse.ecf.tests.filetransfer plugin) the OutgoingFileTransferTest
class.
I've also included the important code from OutgoingFileTransferTest below.
and the process? thanks!
Sure, hope this helps.

We are using Smack 2.2.1 library to implement the ECF xmpp filetransfer.
I have not specifically tested against the Openfire 3.3.0 server,
however (we are using 2.4.0 still with ecf.eclipse.org and this is all
that I've been able to test against to this point).
So this seems likely to be a problem with Openfire 3.3.0<->Smack 2.2.1
file transfer interop. Would you please file a bug here?
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=ECF
As well, would you be able to turn on logging on the Openfire 3.3.0
server and report any notifications caused by the send file request?

Hi Scott!
I am very sorry for saying up that have wasted you time
the problem has been solved!thanks!
there was no something seriouly,
what I have done was that I tested the source code just on one machine
when I use two,there was no problem,no question about the compatible between ECF and Openfire 3.3.0 file transfer specification
Now I can use the file transfer API to implments file transfer functions.
