Problems/Exceptions with FileTransfer

Hi,

we are having problems with the Smack File Transfer.

If the sender sends a file, he gets this exception:

No response from server.:

And the recipient gets this exception:

Both are connected by using a host file entry (C:\Windows\System32\drivers\etc\hosts) to resolve the server name to an IP address.

Is this the problem?

Hard to tell. I can only point you to https://github.com/Flowdalic/asmack/wiki/aSmack-XMPP-File-Transfer which is for aSmack but still applies to Smack.

I’ve analyzed this a bit, but haven’t come too far.

Please can anybody help me here?

I’ve tested with 2 clients both using Spark 2.6.3 (should use Smack 3.2.1) and it works (I guess over IBB).

Then I test my client and send a file to the other Spark client and it works, except I don’t get any progress updates.

Then the other Spark client sends a file to my client and it doesn’t work. (I get the receiver error above).

I studied the Spark code and it just uses the Smack API, so I really wonder, where’s the difference.

Is there some connection configuration maybe?

Does anybody know, what have been fixed in between Spark Version 2.5.8 and Spark 2.6.3 concerning this error?

Because I am still struggling with it and according to this http://community.igniterealtime.org/thread/44600

it could been fixed in Spark.

I debugged Spark and it just uses the same Smack file transfer. So I don’t know what should be different with my implementation.

Is there anything in the SmackConfiguration to be done?
