So this is 1:1 versus 1:n in terms of service point to beans relation.

Sorry, I haven�t looked at the BeanFactory and what it does. But it seems that it
does not as much as the BuilderFactory can do concerning object creation?
Just for me to understand:
If ServicePoint(Impl) - ServiceModel (and its implementations) would be refactored
such that the caching would get part of the ServiceModel, than BeanFactory would
become obsolete. Assuming my �new instance� service model exists.

That is what the BeanFactory (part of the library) is for ... however, it would be nice if it were possible to do dependency injection with pojos.

Well, I guess that the use case does not really fit what Hivemind is intended to do and it wouldn�t be a problem if that would not be possible. But I first thought that the service models give me the freedom to implement whatever I need/want. Maybe I should have read the JavaDoc of ServiceModel more carefully!
However, the intention is to use Hivemind also as a kind of object factory (not only as a service factory) to retrieve programmatically objects from the Hivemind-Registry, which have state. This could also be done by plain Java factories. But why not reuse the rich toolset of Hivemind for constructing POJOs.

I missed what you are trying to do, I thought this was something previously discussed, but it's new.
What's your use case? Why would you need this? What do you get that threaded or pooled doesn't give you.

I have looked at the ThreadedServiceModel and I can not see how I can realize that I get for each service request a new instance of my service. The only thing I can do is to get for each method invocation on a service a new instance. But this is different from what I want. Am I missing something?
Prototype? I would not associate this term with that what I need. Isn�t a prototype not something unique?

A good name for this would be "prototype", because that's what Spring uses for the same concept.
Look at how ThreadedServiceModel works.
You basically need a proxy that obtains a fresh instance from the ServiceModel for each method invocation.

I tried to create a �new instance� service model. This service model should create for each service request a new instance. But as I found out this is not possible because ServicePointImpl �caches� the service once created.
My question - independent on how usefull a �new instance� service model might be - is: Shouldn�t this caching not be part of the specific service model? I think the current solution limits the usage of service models.
