    Description

      OSGi containers and other modular environments tend to hide service files and consider them implementation details. That means that a naive current classloader based implementation won't discover the various CDI implementations.

      There are several approaches to try and work around this problem in EE specs

      JPA 2's approach

      JPA 2 does have a static getter / setter pair

      PersistenceProviderResolverHolder.getPersistenceProviderResolver()
      PersistenceProviderResolverHolder.setPersistenceProviderResolver()


      which holds the resolver to use. A modular environment is free to override the default resolver.

      Bean Validation's approach

      Bean Validation uses a different approach to work around the nasty static field.

      Validation
        .byDefaultProvider()
          .providerResolver( myOSGiResolver )
        .configure() //we have ways to customize the ValidatorFactory further
        .buildValidatorFactory();
      

      Note that Bean VAlidation approach has another benefit, you can physically ask for a specific Bean Validation provider implementation

      Validation
        .byProvider( HibernateValidator.class )
        .configure()
          .ignoreXmlConfiguration() //bean validation configuration
          .failSafe() //Hibernate specific configuration (type safe)
        .buildValidatorFactory();
