Gunnar Morling commented on HV-570:
-----------------------------------

I've spoken to a friend of mine who knows the ins and outs of OSGi. He recommended that we export the services programmatically using the service activator of our bundle. That's not as elegant but it's the approach with highest portability (the infrastructure for DS/Blueprint Services might not be provided/enabled in every case).

What's about custom message interpolator, traversable resolver, etc. Basically everything you can configure in validation.xml?
{quote}

I think the default {{Validator}} and {{ValidatorFactory}} exposed as OSGi service should be configured based on {{validation.xml}}, similar to the default validator (factory) in JEE/CDI. If a user wants to expose a specifically configured validator or factory, I think she could do this and upon service retrieval she could select the right service by specifying a filter (AFAICS that's roughly equivalent to CDI qualifiers).

{quote}
I am thinking about multiple BV implementation all exporting the ValidatorFactory - how would I select between them?
{quote}

This could also done by using a filter, alternatively there is the concept of "ranking", which specifies an order between several implementations. As fallback the order of service registration is used.
