ConfigAdmin and iPojo
Hi all,
I've got a question regarding the OSGi ConfigAdmin service used in
association with iPojo.
Here is what I want to do:
I've got 2 Felix instances in my architecture.
One of these instances is currently running, the other one is stopped.
If I change some configurations in the running instance of Felix using the
ConfigAdmin service in association with iPojo, all my iPojo instances are
correctly created/updated in this Felix instance.
What I want when starting the second Felix instance is all the existing
iPojo instances to be updated with the same configuration (the one modified
in the first Felix instance) before starting.
Of course, to do that our application is responsible to store the
configuration of instances in a central repository to be accessible by all
my felix instances.
My question is: what is the best technical solution to update an iPojo
instance configuration before starting it?
Do I have to manually modify the configuration files in the "cache" folder
of the second Felix instance before starting it?
Thank you for your advices
Olivier

I am using SpringDM, but declarative service is just the same.
Using services with method injection
*XML*
<component classname="my.consumer.Implementation">
<requires>
<callback type="bind" method="bind" />
<callback type="unbind" method="unbind" />
<callback type="modified" method="modified" /> <!-- for
filtered service dependencies, to be notified when a service is
modified but still match -->
</requires> </component>

Hi,
What do you mean by "while the ipojo instance is being registered"?
How to be triggered when it is happening?
Is there a callback method that is always called when it is happening?
Thanks

I mean while the ipojo instance is being registered, you can update it by
configAdmin service according to the stored data from the central
repository.

I think you can use the configAdmin service to update the ipojo instances of
the second felix instance while the bundle is initiating, or the ipojo
service is been registered.

Well, not Felix the framework, but the Felix Config Admin
implementation...I guess that's how it should work...

RE: ConfigAdmin and iPojo
Posted by Bigard Olivier <ob...@axway.com>.
If I understand correctly, we have to implement our own ConfigAdmin PersistenceManager implementation to not store/load configs from file system, but directly from our DB. Am I right?
And we just have to expose our implementation of this PersistenceManager OSGi service and Felix will use our own, not the default one.
Thanks

Perhaps I'm missing something, but if your instances are configured with
Config Admin, then you just need to make sure it has the updated values,
no? If you are using a shared configuration database for Config Admin,
then when iPOJO starts in the second framework, it will use the updated
config data, won't it? iPOJO doesn't save this configuration or the
instances some place, it is recreated each execution.

Perhaps I'm missing something, but if your instances are configured with
Config Admin, then you just need to make sure it has the updated values,
no? If you are using a shared configuration database for Config Admin,
then when iPOJO starts in the second framework, it will use the updated
config data, won't it? iPOJO doesn't save this configuration or the
instances some place, it is recreated each execution.
