I’m not sure I understand what you are trying to do, since you keep mentioning ManagedServiceFactory but I don’t see any such in your code, and they don’t play well with DS. I think you want to have a factory component (i.e. ComponentFactory) where the newInstances are registered with DS as components accepting factory configurations, so you won’t actually get a component instance until a configuration is supplied for one of the “newInstance” components. This isn’t possible and can’t really be done since newInstance essentially returns the single instance, and you want multiple instances.
Since it’s all the same component code, why are different factoryPids useful rather than some other configuration element? thanks david jencks > On Mar 25, 2019, at 12:01 PM, Matthias Leinweber > <[email protected]> wrote: > > ... i can iterate over "my" servicefactories. > > From: Matthias Leinweber > Sent: Monday, March 25, 2019 8:00:25 PM > To: [email protected] > Subject: Re: AW: AW: AW: ComponentFactory > > Mhm OK. > > I will try to explain what i want to achieve. > > My Plan was to create several ManagedserviceFactories all with different > factorypids but all with the same prefix.
