Question about Deployment Admin and Bundle Repository.
Hello all,
I need help understanding Deployment Admin service. Is it like the Felix
OSGi bundle repository service, but instead of treating bundle, it treats
deployment packages (which can be summarized as groups of bundles)?
Is there an implementation of the deployment admin in Felix?
Thank you very much!
Sincerely,
Mathieu Plourde

I agree. We have already used an OBR to store other types of artifacts
(not just bundles) and I think that makes a lot of sense.

I agree that something like this would be useful. I wrote a simple
shell command that at least makes it easy to install/update/uninstall
deployment packages much like one can do right now with bundles. I
might get around to commit it to my sandbox during the weekend.

To my knowledge nothing specific for Deployment Packages exists. But as
the OBR is sufficiently generic, it might be possible to extend it to
also support Deployment Packages. Not sure, though. But I agree, that
this would be very helpful.

Re: Question about Deployment Admin and Bundle Repository.
Posted by Mathieu Plourde <ma...@gmail.com>.
In the Deployment Admin implementation of Felix, is there something to treat
deployment package repositories? Let's say I want a repository of deployment
packages on a server, is there anything similar to what the OBR does, but
for deployment packages? Is there a standard for that? In my application,
the user would input the URL of the repository, and from a file (like
repository.xml for the OBR), the service could download and deploy the
deployment packages. Does it exist?
Thanks.

It's no longer part of the mobile spec, but part of the R4.1
compendium, available from that same location.

Not really. The only thing is that the deployment admin will try to
rollback if something goes wrong when the dp gets installed.

They behave as if they were installed separately.

Yes, it's described in the mobile spec. You can download it from www.osgi.org.

Once deployment of the package is complete, does it have any effect in
runtime? Does it create a namespace of its own, or the bundles that get
deployed as part of the deployment package behave as if they were
installed separately?
Actually, I am looking for a spec document to learn more. Is there one?
I don't want just the javadocs.

Both have kind of similar goals: Easier deployment. But there the
analogy ends.
The OBR is just a repository of bundles with a descriptor file - usually
called repository.xml - which lists all bundles provided along with
their properties, capabilities and requirements amongst them. A user of
the OBR will select bundles required for his application and the bundle
repository code will automatically resolve any missing requirements
using other bundles from the OBR.
The Deployment Admin on the other defines a packaging specification
(with extensibility) to package multiple bundles into a single package
and deploy it to some running OSGi frameworks. The deployment package
may declare further dependencies which must be resolved in the framework
to successfully deploy the package. The Deployment Admin spec also has
some installation guaranetees in it such as transactionality in some
sense: installing a Deployment Package is an all-or-nothing game: Either
the package insalls completely or not at all if there occurr some
problems while trying to install.
> Is there an implementation of the deployment admin in Felix?
Yes, we got a recent contribution which is in the deploymentadmin
project in the Felix SVN trunk.

Hope this helps.
