Hi there,

int packetReplyTimeout = 15000;     // 15 seconds.

I've been trying to use this SmackConfiguration.setPacketReplyTimeout(packetReplyTimeout); I've been trying to use this in a chat app, but I cannot get it to work.

I have this use case:


User A is sending messages to User B, at this point, both users are online, and everything is working as expected, the problem comes when for some reason, User B gets disconnected, let's say he lost connection, so there's no time to tell the server that I went offline. So then when User A sends a new message to User B, there's no response back within the packetReplyTimeout value (15 seconds).

After some time, I get the next stanza:


<message from='' to='' type='error' xml:lang='en' id='123-abc'>

    <archived by='' xmlns='urn:xmpp:mam:tmp' id='id-123' />

    <stanza-id by='' xmlns='urn:xmpp:sid:0' id='id-123' />


    <markable xmlns='urn:xmpp:chat-markers:0' />

    <request xmlns='urn:xmpp:receipts' />

    <error type='cancel'>

        <service-unavailable xmlns='urn:ietf:params:xml:ns:xmpp-stanzas' />

        <text xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'>User session terminated</text>




So I look for the <archived extension, and if it is there, then I mark the message as sent, the problem is that sometimes that stanza is coming after 20 seconds, or sometimes after 5 minutes, so I would like to get the SmackConfiguration.setPacketReplyTimeout(packetReplyTimeout); working, so I can notify this before that long period of time.

And finally my question would be: is there anything that I need to do to get the SmackConfiguration.setPacketReplyTimeout(packetReplyTimeout); to work?


I am using 4.2.0 library version.
