Unique names are not required, as ServiceTracker as well as @Reference annotations do support multiple matches for filters. In case two TcProvider would use the same id, users would get the one with the higher "service.ranking" injected. In case both have the same "service.ranking" the one with the lower "service.id" is injected. Services that are started earlier will have the lower "service.id". best Rupert > > Cheers, > Reto > >> >> >> May the Subject be with you ! >> ++ >> >> >> On 02/08/2013 02:48 PM, Reto Bachmann-Gmür wrote: >> >>> Hi Florent >>> >>> Rather than checking the weight you you could check the class with >>> getClass() but this sound like a hack as well. >>> >>> Another approach would be to add a service property to the TcProvider so >>> you can filter by it when you want this particular one: >>> >>> @Reference(name="provider", referenceInterface=** >>> WeightedTcProvider.class, >>> target="(my.very.special.one=**true)", >>> cardinality=**ReferenceCardinality.;**AMDATORY_UNARY, >>> policy=ReferencePolicy.STATIC)**, >>> >>> Have a triple good day! >>> Reto >>> >>> On Fri, Feb 8, 2013 at 2:17 PM, florent andré < >>> florent.andre-dev@4sengines.**com <florent.andre-...@4sengines.com>> >>> wrote: >>> >>> Hi there ! >>>> >>>> Working with multiple TcProvider I would like to get one in particular. >>>> >>>> The way I find for now is to call : >>>> SortedSet<WeightedTcProvider> providerList = tcManager.getProviderList(); >>>> >>>> And then iterate throw my providerList, and select the one I would like >>>> by >>>> his "weight". >>>> >>>> "Weight" is really not an "user friendly" (nor reliable) property to >>>> select something in a list imo... but I don't see any selection method >>>> based on a name or an ID. >>>> >>>> Do I miss something here ?
