Hi, just create a factory and use Guice to inject it. But I do not think it's a good idea to add Service or Repository to Domains. You may want to implement Evans DDD, but please check this :http://www.udidahan.com/2008/02/29/how-to-create-fully-encapsulated-domain-models/
If it is possible, do not add service or repository to Domains.
