Subject:
Given an eba file (with out the deployment manifest), I would like to resolve dependencies from a stand alone Java Application. I had a look at various Aries Application APIs and they seems to be able to do the job that I want, but I am finding it hard to put them together. Sounds like AriesApplicationManager is a good start, but it is not clear how to get that one. Could anyone let me know, if this possible and if it is possible, where to start?
Regards
Sankar

Hi Sankara,
That's a clear explanation of what you're trying to do. I believe this is
the first time that we've heard someone talk about provisioning OSGi
applications from a plain JSE environment. The suggestions above are valid:
I would definitely support getting this working on an OSGi runtime first.
That will be easier since it's the normal usage of the code in question.
Once you've got that working, you can decide whether the cost of porting it
to something like PojoSR is worthwhile. Good luck - do let us know how you
get on!
Regards,
Mark

Thank you guys. They are all useful suggestions. I will follow your suggestions and see if they could help me.
At a high level this is what we are trying to do:
Our deployment environment is a self contained environment and shouldn't depend on external resources (maven repos etc) to run the application. This deployment environment is OSGi based Geronimo G3.
In order to do that, we have a packaging step (this is non OSGi, standard java application), in which we resolve dependencies, get all the needed bundles and package them together for the deployment environment. As of now, we use Geronimo G3 even in this step to resolve all the dependencies of the eba file. So, we wanted to get away from using G3 in this stage and resolve the dependencies in a programmatic way, either using OBR Resolver or Aries application API.
Regards
Sankar

Sankara, Graham has described how you get this running in a non-OSGi
runtime. Is this what you want? I didn't read that into your initial
email. The 'twitter' sample ... see trunk/samples/twitter may help. It
configures the Felix OBR repository with a repository.xml, then uses
the AriesApplicationManager to create an AriesApplication which it
then resolves, after which the DeploymentMetadata object is retrieved
from the Aries Application. It's about the simplest deployment
manifest creation example that includes a repository configuration
step. Of course that may not be quite what you want!!

Sankara, Graham has described how you get this running in a non-OSGi
runtime. Is this what you want? I didn't read that into your initial
email. The 'twitter' sample ... see trunk/samples/twitter may help. It
configures the Felix OBR repository with a repository.xml, then uses
the AriesApplicationManager to create an AriesApplication which it
then resolves, after which the DeploymentMetadata object is retrieved
from the Aries Application. It's about the simplest deployment
manifest creation example that includes a repository configuration

Hi Sankar,
You probably want to get the set of bundles working in an OSGi
environment first. Some of the tests in Apache Aries should be able
to give you a head start on determining which these are (Mark may be
able to give more specific pointers than me). Once you've done that,
you could try using pojosr to run that set in a non-OSGi runtime
(http://code.google.com/p/pojosr/). PojoSR would be necessary if the
bundles you are using make use of the OSGi service registry. It will
allow the service registry interactions to continue to work in a
non-modular, flat classpath, environment.
I hope this helps.
Regards, Graham.

Hi Mark,
Thanks for the reply. Generating deployment.mf is my first problem to solve.
What I need to do, given an eba file as an input, my application has to read the application.mf, read the top level modules and resolve (download) the dependencies.
Regards
Sankar
