It can, because DocShare uses the datashare API.

Actually, the way docshare works now is that if an IContainer is 
connected, and the IContainer supports/has a IChannelContainerAdapter, 
then docshare is started for that container/connection (since all 
docshare requires is the datashare api.  So in effect, what I'm saying 
is that if a jms container were to be connected, then docshare would be 
started just by that happening.  See the class 
org.eclipse.ecf.internal.docshare.ECFStart in docshare plugin.

The current docshare user interface (the editor context menu), however, 
depends upon having the provider support the presence API...since the 
user presence is used to get the ID of the target for the shared editing 
(i.e. the receiver).  So even though the docshare functionality is there 
(as per previous paragraph), there's no way to initiate a shared editing 
session in the UI (as yet).

One thing I should let you know...as per this bug/enhancement request

https://bugs.eclipse.org/bugs/show_bug.cgi?id=234142

we are in the process of refactoring docshare to move the 
synchronization/cola parts to a separate plugin (a new API plugin called 
org.eclipse.ecf.sync for the sync API).  This API (with cola 
implementation underneath) provides access to a 'synchronization 
strategy' that can be used by other apps for synchronizing document 
changes (i.e. other than docshare).  Right now, Marcelo Mayworm is 
working on changing over the docshare app to use this synchronization 
strategy API.

It's my understanding that IBM Websphere Community Edition is actually 
ActiveMQ...although I don't know what version of ActiveMQ the IBM 
Websphere Community Edition actually uses.  But I believe they should be 
compatible (but again I'm not certain of that).

Sure.  I apologize for all the trouble (e.g. the no user interface for 
providers that support datashare but not presence API).  But with your 
help we will get you going with cola/docshare, etc.  :)

Thanks,

Scott
