Exactly what code fragment would I use to configure a vanilla Jersey Client instance to "keep-alive" connections? Thanks!

Client-side keepalive: Clients sends TCP keepalive to prevent the server from closing the TCP connection to the client. No. Client sends keepalive so that if the server is dead, the client will get a 'connection reset' error, after which it should close the connection.
There are three usages of TCP alive: Server-side keepalive: The server sends TCP keepalive to make sure that the client is alive. Client-side keepalive: Clients sends TCP keepalive to prevent the server from closing the TCP connection to the client. Both-side keepalive: Both server and clients send TCP keepalive as described in 1 and 2.
Jersey Client Example – Jersey 2 Client API. Jersey 2 client API finds inspiration in the proprietary Jersey 1.x Client API. In this Jersey client example, we will learn to build client API and invoke different REST methods and consume the API results. Table of Contents 1. Jersey Client Maven 2.
Dropwizard includes both Apache HttpClient and Jersey Client. Let’s build out them. Dropwizard client module is added as separate module. Dropwizard provide easy to declare and use REST client configuration. You need to create io.dropwizard.client.JerseyClientBuilder instance and give it io.dropwizard.setup.Environment reference.
Assuming you mean HTTP keep-alives, it is supported by default and can be controlled by system properties.
Jersey client uses HttpURLConnection class internally, so http://docs.oracle.com/javase/6/docs/technotes/guides/net/http-keepalive.html does apply for it as well.
