Hi!
I am looking for xmpp / jabber protocol implementation for Delphi 7. IP*WORKS! is one of solutions, but it is expensive. I saw Any complete library for Jabber in Delphi? question and JOPL was the answer, but it is not for Delphi 7. What do you use for Jabber and Delphi 7?
I'd suggest taking a look at the Open Source XMPP client written in Delphi: Exodus. More info on the client here, http://www.jabberstudio.org/projects/exodus/project/view.php. I'd imagine their code is either already modularized so you can use (depending on license suitability) or you can rip it out and make it a module. Not as ideal as an off-the-shelf library, but should work.
