Unsatisfied dependencies for type […] with qualifiers [@Default] at injection point (using @Stateful EJB with CDI)

Question

I have the following code to manage two kinds of repositories. Both repository classes inherit an interface to allow reinitialization of their resources.

pub         


        

Answer 1

I had the same problem with this misleading exception...

By adding @Stateful to UserRepository you expose EJB methods of the CachingRepository interface without having a no-interface view declared. Add @LocalBean to UserRepository to activate the no-interface view. See EJB 3.1 Specification, Section 4.9.8 "Session Bean's No-Interface View"

The bean class must designate that it exposes a no-interface view via its bean class definition or in the deployment descriptor. The following rules apply:

• ...
• If the bean exposes at least one other client view, the bean designates that it exposes a no-interface view by means of the @LocalBean annotation on the bean class or in the deployment descriptor.
• ...

I also refer to this stackoverflow answer for more information about no-interface views.
