How do i accept a persence subscription request [message #618913]

I am using XMPP with ECF to create a chat program (and subsequently put
ECF for more complex uses.)

I have managed to build most of my chat program. But what I still am not
able to do is to accept subscription requests from other chat users.

I am able to see subscription requests using a subscription listener. But
when I get the subscription request, how do i accept it?

Thanks,
Rakesh

Very interesting, it does seem like we do not expose any such APIs. It
may be that the intent was that when you got a notification, you would
have your own dialog that would accept (which in that case you'd
subscribe to them) or you'd reject (in this case you'd block them).

We have no APIs for blocking people at the moment, though.

This wasn't something I caught while reviewing the presence APIs,
unfortunately.

Rem

I have got the answer to my question. See this link:
http://dev.eclipse.org/newslists/news.eclipse.technology.ecf /msg00099.html

Extract from this post:
"
The steps to the subscription process seem to be as follows:
1) The requesting client calls addRosterEntry on the IPresenceSender with
indications about who to add.
2) The authorizing client receives a handleSubscribeRequest event on the
ISubscribeListener with the IPresence object flagged as SUBSCRIBE.
3) To authorize a subscription, the authorizing client calls
sendPresenceUpdate on the IPresenceSender with the IPresence object
flagged as SUBSCRIBED.
4) To deny authorization the authorizing client can call
sendPresenceUpdate with the IPresence flagged as UNAVAILABLE.
5) The requesting client receives a handleSubscribed event on its
ISubscribeListener with the IPresence object flagged to indicate the
outcome.

Interesting. Thank you for this link, Rakesh. I didn't go through the
whole discussion since it's rather long but did notice a few API
comments he made that were confusing / seemingly useless to me at the
time when I was reviewing the presence API several months ago.

One thing that's always bothered me about the presence APIs is that it's
modeled too closely to the Smack APIs.

Rem

As people can probably tell by last year's discussion referenced above,
the similarity to the Smack APIs has become less and less true over
time. That trend will continue as the committers move the APIs forward.

So, Rakesh my question to you is, do you want a separate/additional/new
API for responding to subscription requests? If so, could you describe
your use case a little further, and/or file an enhancement request
against the presence API for this?

Thanks,

Scott
