It sounds to me that your problem could also map rather nicely to a
Managed Service Factory?
I always disliked DS factories, so I a biased :-)
Kind regards,

Hi Neill,
Thank you for your support.
Do i need to take care myself about component instance objects or
it's possible to retrieve them in some
way from OSGi framework???
Another point tham i'm still a little confused is the
interoperability of DS and CM.
As you know i want to create my components with component factories
this will happen with deployment file
on some folder, now
1) Creating components/services ( ok is done by component factories
invoked by my deployer-service )
2) Unregistering is done by ComponentInstance.dispose()
Now the last part i miss i the "update" of the component when the
deployment file is update. My idea is that
my component will provide the ManagedServiceInterface.
Is this the right way to proceed???
Bye
Andrea

Andrea,
To create the component instances you must have called newInstance()
on ComponentFactory. This returns an object of type
ComponentInstance... to destroy the instance and unregister its
services, just call the dispose() method on ComponentInstance.

Hi all,
I've developed a ds component factory that create instances of my
component
on demand, my component
provide a service according to a particulare java interface
But in my requirements i need both "create" and "remove component
instances"
depending for example by
adding ( creating components/services ) or removing ( removing the
related
components/services ) files
from a specified folder.
I've just achieved the creating use case writing a component that
mantains
the reference to the component factories and
provide to create my components on demand....
What i need now is to have a way to undeploy some of this when
"the related
deployment" file is removed
by the deployment folder.
Which is the best way to do that???? I know services are
automatically
unregistered when the bundle that create that service stop,
but in my case i'm using ds and a component factory so it's not
clear wich
is the right way to proceed.
Thank you for your help...
Andrea
