XMPPFramework - Retrieving Openfire Message Archives

Question

Spent hours trying to solve this problem and I'm stumped!

Trying to grab the Chat History between 2 users on my OpenFire server and I read that I plugin was needed to do this.

So, I installed the 'Open Archive' plugin on my OpenFire server and send the following XML (as per the XMPP-0136 protocol documentation):

<iq type="get" id="page1">
   <retrieve xmlns="urn:xmpp:archive" with="[email protected]" start="1469-07-21T02:56:15Z">
      <set xmlns="http://jabber.org/protocol/rsm">
         <max>100</max>
      </set>
   </retrieve>
</iq>

In code, this is achieved via the following:

NSXMLElement *iQ = [NSXMLElement elementWithName:@"iq"];
[iQ addAttributeWithName:@"type" stringValue:@"get"];
[iQ addAttributeWithName:@"id" stringValue:@"page1"];

NSXMLElement *retrieve = [NSXMLElement elementWithName:@"retrieve"];
[retrieve addAttributeWithName:@"xmlns" stringValue:@"urn:xmpp:archive"];
[retrieve addAttributeWithName:@"with" stringValue:@"[email protected]"];
[retrieve addAttributeWithName:@"start" stringValue:@"1469-07-21T02:56:15Z"];

NSXMLElement *set = [NSXMLElement elementWithName:@"set"];
[set addAttributeWithName:@"xmlns" stringValue:@"http://jabber.org/protocol/rsm"];
NSXMLElement *max = [NSXMLElement elementWithName:@"max"];
max.stringValue = @"100";
[set addChild:max];

[retrieve addChild:set];
[iQ addChild:retrieve];

[[[self appDelegate] xmppStream] sendElement:iQ];

Which returns the following error:

<iq xmlns="jabber:client" type="error" id="page1" to="[email protected]">
   <error code="404" type="cancel">
      <item-not-found xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/>
   </error>
</iq>

My Xcode project can successfully send/receive messages to the user I'm trying to receive chat history from so I really don't know what I'm doing wrong. Also the Plugin enables me to search through Chat Messages (via OpenFire admin) with successful results so it seems to be working and storing the messages.

Any help would be appreciated. Thanks!

If you are looking for a chat history, I think you have to save the messages to core data and retrieve them from there. For saving data using the XMPPFramework inbuilt functionality, you have to use this code:

XMPPMessageArchivingCoreDataStorage *storage = [XMPPMessageArchivingCoreDataStorage   sharedInstance];
NSManagedObjectContext *moc = [storage mainThreadManagedObjectContext];

xmppMessageArchivingStorage = [XMPPMessageArchivingCoreDataStorage sharedInstance];
xmppMessageArchivingModule = [[XMPPMessageArchiving alloc] initWithMessageArchivingStorage:xmppMessageArchivingStorage];
[xmppMessageArchivingModule activate:xmppStream];
[xmppMessageArchivingModule  addDelegate:self delegateQueue:dispatch_get_main_queue()];

Now you have to retrieve that messages from core data by this:

-(void)loadarchivemsg
{  
    XMPPMessageArchivingCoreDataStorage *storage = [XMPPMessageArchivingCoreDataStorage sharedInstance];
    NSManagedObjectContext *moc = [storage mainThreadManagedObjectContext];
    NSEntityDescription *entityDescription = [NSEntityDescription entityForName:@"XMPPMessageArchiving_Message_CoreDataObject"
                                                      inManagedObjectContext:moc];
    NSFetchRequest *request = [[NSFetchRequest alloc]init];

    NSString *predicateFrmt = @"bareJidStr like %@ ";
    NSPredicate *predicate = [NSPredicate predicateWithFormat:predicateFrmt, chatWithUser];
    request.predicate = predicate;
    NSLog(@"%@",[[NSUserDefaults standardUserDefaults] stringForKey:@"kXMPPmyJID"]);
    [request setEntity:entityDescription];
    NSError *error;
    NSArray *messages_arc = [moc executeFetchRequest:request error:&error];

    [self print:[[NSMutableArray alloc]initWithArray:messages_arc]];
}

-(void)print:(NSMutableArray*)messages_arc{
    @autoreleasepool {
        for (XMPPMessageArchiving_Message_CoreDataObject *message in messages_arc) {
            NSXMLElement *element = [[NSXMLElement alloc] initWithXMLString:message.messageStr error:nil];
            NSLog(@"to param is %@",[element attributeStringValueForName:@"to"]);

            NSMutableDictionary *m = [[NSMutableDictionary alloc] init];
            [m setObject:message.body forKey:@"msg"];

            if ([[element attributeStringValueForName:@"to"] isEqualToString:chatWithUser]) {               
                [m setObject:@"you" forKey:@"sender"];
            }
            else {
                [m setObject:chatWithUser forKey:@"sender"];
            }

            [messages addObject:m];

            NSLog(@"bareJid param is %@",message.bareJid);
            NSLog(@"bareJidStr param is %@",message.bareJidStr);
            NSLog(@"body param is %@",message.body);
            NSLog(@"timestamp param is %@",message.timestamp);
            NSLog(@"outgoing param is %d",[message.outgoing intValue]);
            NSLog(@"***************************************************");
        }
    }
}
