You'll have to use dynamic priority binding policy for the dependency so
that you are automatically switched based on service ranking...if you
just use dynamic binding policy for the dependency, then you'll just get
the highest ranking at the time of injection.

Thanks!
It seems like an elegant solution. :)

I think you would want to utilize the service ranking:
When registering a service object, a
bundle may optionally specify a
service.ranking number as one of
the service object's properties. If
multiple qualifying service interfaces
exist, a service with the highest
SERVICE_RANKING number, or
when equal to the lowest
SERVICE_ID, determines which service
object is returned by the Framework.
Make Aa the highest rank, Ab after that. That way it will get the Aa
service if available, Ab if not.

Hi David
Still the question remains.
The log service is an example.
If I have 2 service implementations Aa and Ab of interface A.
If I have a client that uses Aa and can use Ab. In case service Aa is
unavailable, is it possible via iPOJO to switch automatically to service
Ab?

Sounds like you should be using the LogReaderService for those
implementations not the LogService. You can use the Felix Log Service
bundle to get a LogService implementation and Log Service APIs.

Subject: iPOJO: How to use an alternate service when the current

is unavailable?
Hi all
I have the following situation:
I have 2 Log service implementations implementing *LogService*
interface:
1. *Console* log implementation
2. *RotatingFile* log implementation
I want that a service SOME_SERVICE will use the *Console* log
implementation
service as a default, and if it is unavailable, SOME_SERVICE will use
the *
RotatingFile* log implementation service instead.
Is it possible to do that?
If it does, how can I do that?
