[JDEV] Re: Starting a jabber type client for my customers

[Wong, Charles]

Hi Tony,

	Reason why I want to start from scratch is simply because (correct
if I'm wrong) I don't want any legal issues in the future with the
developer(s) of the library(s) and with the GPL. I'd like what I'm
developing to be sold with my jabber client integrated in the application.
I'll actually be more than happy if I don't have to start from the utter
beginning, but I just wanted to be safe than be sorry. Ya know? Thanks!

Cheers,
Charles Wong

Hi Charles,

I wonder why you want to develop a Jabber client without using any 
existing library or client. If you really want to start from scratch, 
Jabber is one the easiest IM protocol available for implementation.

I think you could start first from choosing an XML parser, as Jabber is 
based on XML. Then you could start to learn the protocol by trying some 
existing Jabber clients. Most of them could reveal the actual underlying 
XML data that are sent. Then you could look at the Jabber protocol 
itself, http://www.jabber.org/protocol/, especially the two IETF 
internet drafts, http://www.jabber.org/ietf/.

Best Regards,
Tony Cheung
