Re: [ecf-dev] Google Summer of Code Application

Hi Andrew,
Andrew Nelson wrote:
Hey guys,
I purposed an IM for Eclipse for my Summer of Code application. I did
this without knowing about ECF and now that I do, I've revised my
application. I'd like to make a RCP application using ECF. It'd be
aimed at meeting developers needs, but would also be a fully
functional instant messenger.
This is a nice idea I think. We had an RCP version of a (very) basic IM
client...called rcpchat, and this project is still in the ECF OSUOSL
repository here:
:pserver:anonymous@xxxxxxxxxxxxxxx:/ecf
applications/org.eclipse.ecf.example.rcpchat
This is very rudimentary, however, and we have not been maintaining it
(although it still build fine in my workspace I think some of the bundle
dependencies are stale and it does not run). Andrew you are more than
welcome to look at this and use the code as a starting point if you
like. If you don't want to use it that's fine too...your decision.
Just by looking around some, I've found
all sorts of cool support in ECF -- for file transfers and
multi-protocol messaging and voice (is this implemented yet?).
Multi-protocol messaging...yes, we've got IM/presence providers for
XMPPS/Google Talk, Skype, Yahoo, and have possible pending contributions
for sametime, and AIM.
XMPPS/Google Talk supports the file transfer API
(ISendFileTransferContainerAdapter is entry point).
RE: voice...we've got a 'call' API (org.eclipse.ecf.telephony.call),
which is an abstract call signalling/setup API. We have working impls
(albeit still minimal UI) for Skype-based calling, and Moritz Post's
work last year on integrating Jingle. Here are some links for details:
http://wiki.eclipse.org/VoIP_via_the_ECF_Call_API_and_the_Jingle_Protocol
http://wiki.eclipse.org/VOIP
http://wiki.eclipse.org/Skype_Provider
There is also a proposal by Marek Zawirski for 2008 Google SOC project
to work on a SIP provider for the ECF call API. You can see the dialog
about this proposal in the ecf-dev mailing list archives:
http://dev.eclipse.org/mhonarc/lists/ecf-dev/maillist.html
The short of it though is that we have lots of work TBD on VOIP...both
at the level of protocol support (e.g. SIP) and UI work around
initiating calls (i.e. without a buddy list), and presenting call status
and control UI. Moritz had some of this in his 2007 work (Moritz is now
an ECF committer), and Marek's work will hopefully integrate with that work.
I also
saw something very interesting -- Shared Object API. I'll have to
look into that more, but think it could have a lot of potential.
Yes, the shared object API could be useful in a number of ways...we have
a very old and very simple real-time collaboration group support using
the shared object API to implement (the shared object API really is just
an API for dynamically replicating arbitrary java
objects/applications/model state) into a distributed group...and
providing messaging primitives (like failure detection and group
membership info) that allow the objects/applications/models to
synchronize state changes in a way that makes sense for the application
requirements (i.e. from 'optimistic' to 'pessimistic'/n-phase commit
strategies).
Anyway, come check out my application and maybe give me some feedback.
Would you please post a link to the application here?
Thanksinadvance,
Scott
