In documentation at link:

https://docs.jboss.org/resteasy/docs/3.0.19.Final/userguide/html/RESTEasy_Client_Framework.html#d4e2187

It shows the following piece of code:

Client client = ClientFactory.newClient();
WebTarget target = client.target("http://example.com/base/uri");

But the class ClientFactory does not exist. I think it should be ClientBulder.
