Hi
I think i found a bug with service rankings since the comparator
method
of service reference isn't being called. I placed a breakpoint in the
method and got no stop.
you'll need to provide more details like which version of Felix
you're using
and
where you're setting the breakpoint (in trunk the
ServiceReference.compareTo
implementation is actually in ServiceRegistrationImpl.java:452)
also it depends how you're getting the service - if you use the bundle
context
method "getServiceReference(String clazz)" this definitely uses
compareTo
- see the "getBestServiceReference" utility method in
BundleContextImpl:271
but if you're using a high-level framework like iPOJO then it might
be using
its
own implementation of the ranking algorithm to sort services (the
compareTo
method in ServiceReference only appeared in r4.1 of the OSGi spec,
before
that the service ordering was defined in the spec but there was no
compareTo
method defined in the ServiceReference interface)
Could you try an iPOJO trick: set the binding policy of your
'requires' to 'dynamic-priority'.
So, in XML add 'policy="dynamic-priority"', in annotations add:
policy="dynamic-priority".
If it works like this, it's a bug in the 'dynamic' binding policy :-)

Could someone confirm this? I'm creating the services with ipojo but i
dont think thats the prob since the services have the service.ranking
property set.
Thanks
