Thanks. I obviously need to read the Compendium specs... :-)
Will report after that.

Dear ACE users
I have a test setup running with a target and (allinone-)server. I'm using
the server GUI to interact with the target.
I have the following questions regarding ACE. :
- when the agent gets installed on a framework which already has running
bundles, is it possible to retrieve the information, which bundles are
installed and update them using ACE? Can I also uninstall bundles which have
not been provisioned through ACE?
No, the agent can only manage (update/uninstall) packages of resources
resources that it has installed itself in a previous deployment. ACE
is build around the OSGI Deployment Admin Specification (see
Compendium Ch 114).
- how can I assign a bundle start level to a bundle deployed by ACE?
No, you can not as it is not covered by the specification. You could
probably make it work using resource processors and/or a customized
agent. However, in general start levels are considered to be an
anti-pattern, so you should not use them anyway ;)
- how can I choose the initial frameworklevel to which the framework should
start (on next startup)?
Yes, the standard launcher allows you to specify a config file that
can hold system properties in the form of 'system.<systemprop>'. So
you should be able to do this by adding
'system.org.osgi.framework.startlevel.beginning = 3'.
- for specific bundles which are provisioned by ACE, is it possible to
define ConfigAdmin properties and update them later? How should I do this?
Yes, with the help of the Auto Configuration Resource Processor (see
Compendium Ch 115) , you can provision ConfigAdmin properties in the
form of Metatype files (see Compendium Ch 105). Also you are free to
use any format you like as long as you write a Resource Processor that
can handle it.
- with respect to the above - except for the server URL which obviously is
needed on startup, can I configure the agent remotely using the ConfigAdmin
method above (ie. set the identifier, the update interval etc.) after it was
installed?
No, not by default. However, the Agent does expose itself as a
service. This allows you to write custom bundles that can manage
configuration aspects of the agent.

Bram
