ejabberd: retrieve chat history from mysql db

Question

I\'m building a chat system based on ejabberd using an iOS client (and XMPPFramework).

My current chat system supports only one-on-one conversations between users saving

Answer 1

This should be possible with mod_archive_odbc. It's an additional ejabberd module that you can find by checking out http://svn.process-one.net/ejabberd-modules/ with SVN. An example on how to build and install a module on Debian can be found here.

Answer 2

The question is a bit old, but if anyone is still interested.

This could be achieved by Message Archive Management (http://xmpp.org/extensions/xep-0313.html).

Most complete implementation of this XEP is in MongooseIM (fork of ejabberd). https://github.com/esl/MongooseIM/blob/master/apps/ejabberd/src/mod_mam.erl

ProcessOne page claims to have support for archiving on this page: http://www.process-one.net/en/ejabberd/#getejabberd, but there is no mention on this page: http://www.process-one.net/en/ejabberd/protocols/. Looks like they are using their custom specification.

Please note, that you won't be able to use mod_mam from MongooseIM directly with processone ejabberd, because of small differences in function arguments that module is calling.
