Hi Philipp, In the end the configuration specified with the Configurator will end up in OSGi Configuration Admin, so the Configurator is limited to the same types as ConfigAdmin. The Configurator allows complex JSON values to be specified, they will end up as JSON text in Configuration Admin if they go beyond what ConfigAdmin supports natively.
So to use the Configurator you need the Configurator bundle plus the ConfigAdmin bundle. The Configurator handles configuration resources in OSGI-INF/configurator inside bundles but can also be provided with external configuration via the configurator.initial framework/system property. This is described in sections 150.4 and 150.5 in [1]. To provide Configurator configuration into the system you don't need to write any classes, but depending on how you use the configuration you may have to add classes that consume it. But again, the consumption can be done by anything that understands ConfigAdmin configs, so there are a lot of options for this. I'm not aware of a complete tutorial on this topic yet. I agree it would be nice to have that. Hope this helps, David [1] https://osgi.org/specification/osgi.cmpn/7.0.0/service.configurator.html On Thu, 12 Jul 2018 at 10:55, Philipp Höfler <philipp.hoef...@pernexas.com> wrote: > Hi, > > I am searching for a possibility to load complex configurations. > I tried the ConfigurationAdminService, but key value pairs are not > sufficient as I need complex types. > > Raymond pointed out that I should have a look at the Configurator > Specification. > https://osgi.org/specification/osgi.cmpn/7.0.0/service.configurator.html > > I read the specification and it sounds promising. > But I am stuck how to use the Configuration in my project. > I understand that I've to add the following dependency. > org.apache.felix.configurator > > But I don't understand if I've to add some classes, where the json file > has to be placed and if it's possible to place it outside of the bundle? > > Is there any tutorial or sample project out there? > > Thanks, > Philipp >
