That URL is an attempt to connect to Openfire's internal web server directly, so Apache is not involved at all. I think you'd be better served asking on the Openfire mailing list. It seems to me that the BOSH part is not getting enabled for some reason.
Note that unlike other BOSH endpoints, I believe Openfire does not work with normal GET requests, it will only work with HTTP POSTs from a BOSH client. The normal sanity check of visiting the URL in your browser will fail. Are you visiting the page directly or attempting to use that URL with strophe? If with Strophe, are you seeing a 404 that way?
