I have been asked to integrate Facebook Chat to my application using JavaScript only. I cannot use X Facebook platform authentication as it needs a domain URL. So my option is to set up an XMPP chat client using strophe.js via a digest MD5 SASL mechanism.
Regarding BOSH connect manager, http://bosh.metajack.im:5280/xmpp-httpbind. Is this enough or should I configure it in my server? I am using the Tomcat server.
Facebook does not do S2S federation, only C2S, so you will have to use that as your XMPP server (or implement something like XEP-0100 at your server). Facebook does not currently support BOSH, AFAIK.
from http://developers.facebook.com/docs/chat/
The DIGEST-MD5 SASL mechanism is available to support traditional XMPP or multi-protocol IM clients that are not customized for (or even aware of) Facebook. This mechanism requires prompting the user for his or her password; therefore, it should only be used when necessary. In particular, it MUST NOT be used for any client that:
•Proxies the XMPP connection (the connection must be directly from the user's computer to Facebook).
•Reports messages or any other information about user activity to a third party (including the client developer).
•Integrates with Facebook, or has a Facebook Application ID. If your application does any of the above, you must use Facebook Platform authentication instead.
So, you can't use DIGEST-MD5 with a bosh server but you must use X-FACEBOOK-PLATFORM
