Currently, JSON WebServices are auto-configured by scanning the classpath and scanning the service classes for services.

More robust way would be scanning the Spring application context, and finding all service beans.
Moreover, now we can invoke methods directly on service beans instances, rather then calling them through *Util methods.

This would also make deployment on JBoss AS7 domain mode possible.
