Re: [ecf-dev] How could I setup DistributedEventAdmin using DS ?
|
Well, perhaps you said that could be better to create the container
manually, in case of Hello.DS, the container is being created
automatically, no ?
My goal was to get this created container and use it to setup the
distributed events.... is there a way to get a reference to this created
container ?
Could you tell which class is responsible for this creation task so I
can study it?
cheers

Hi guys,
Could someone point me how could I setup DistributedEventAdmin

No example currently exists. Since some of the
DistributedEventAdmin setup currently requires java code it would
involve some combination of DS markup and java code.
So let me dig into this :)
I'm creating a example based on hello... If you wanted I could sent
you after I've done the challenge... but I need some directions here...
I know now that I can't use DistributedEventAdmin as DS component
because it doesn't have a default constructor...
Reading event example, I conclude that I need to get a reference to
IContainerManager, get the ID of the container, then get the
IContainer, adapt it to ISharedObjectContainer and then add the
DistributedEventAdmin object on it. Am I right?
Yes...that's essentially right. It might be better to create the
container rather than 'get the ID of the container', but still what
you have outlined is fine.
I could get the reference of IContainerManager using DS, but
containerManager.getAllContainers() shows me any container... and I
don't know how to create the ID of container either...
Well, like I said it might be better to create the container (and it's
ID). OTOH, it's also possible to create (and optionally connect) the
container outside the scope of the service component, and then just
retrieve the container from the container factory.
So I couldn't figure out a way to get a reference to IContainer in
the activate method of HelloComponent... could you give a tip how do
that?
You can create a container with the containerFactory (accessible via
the IContainerManager)...e.g.
IContainer newContainer =
containerManager.getContainerFactory().createContainer('ecf.generic.server');
and/or create and connect a
For another purpose, I have done this previously...i.e. used a ds
service component to expose the EventAdmin service, and have the
component's activation result in the creation of a container, the
addition of a DistributedEventAdmin instance to that
container...that's then used by the service component to send/post
events.
Just FYI....I'm going to be away from Internet access for a couple of
days...so although I'm happy to discuss further, it will be next week.
