By default, Errai uses Google Guice to wire server-side components. When deploying services on the server-side, it is currently possible to obtain references to the MessageBus, RequestDispatcher, the ErraiServiceConfigurator, and ErraiService by declaring them as injection dependencies in Service classes, extension components, and session providers.

Alternatively, supports CDI based wiring of server-side components. See the chapter on Errai CDI for more information.
