Is some version of RFC 189 available for reading somewhere?

Thanks BJ. In that case I will try to get involved with the RFC.

I think this is being addressed by RFC 189 which is under discussion.

Subject: [osgi-dev] Obtaining HTTP host and port from HttpService
Sent by: [email protected]
<mailto:[email protected]>
------------------------------------------------------------------------
Hi all,
I'd like to discuss a requirement relating to the HttpService,
which I haven't been able to satisfactorily solve with the present
specification. Perhaps I am missing something that is already
possible, otherwise I hope the following considered for the
updated RFC.
Essentially I want to know the host and port on which the HTTP
service is listening. The challenge is that I need this
information *prior* to any HTTP request being received; ideally at
the time that I register my servlet. My motivation is to work out
the full URL of my servlet and advertise its existence, e.g. using
the discovery aspect of OSGi Remote Services.
The Felix implementation publishes HttpService with a service
property of "org.osgi.service.http.port", which is helpful but
non-standard, and other implementations don't follow the same
practice. Also it doesn't provide a full answer because the host
address is not published... although I can guess at the localhost
address using standard Java calls, that may be wrong on a server
with multiple IP interfaces.
The HttpService according to the spec invokes each servlet's
init() method with a ServletConfig object, which contains a
ServletContext... but as far as I can tell the host and port are
not available from these APIs, even in the latest Servlet spec. Or
have I missed something here?
Any suggestions or comments appreciated.
Regards,
Neil_______________________________________________
