Hi All,
I agree that it is not in the list of topics but that list is quite small.
If you check the course topics of the
training that Oracle is providing you can see that Jersey is part of it:
JAX-RS-based Web Service Clients
Understand how to create JAX-RS clients using URL and HttpURLConnection.
Understand how to create JAX-RS clients using the Jersey Client API.
So I assume that it is also part of the exam.
