Yes it is possible to configure the Jersey Client to connect through a proxy server that requires NTLM authentication.

Here is a simplified code snippet that prepares a suitable ClientConfig that should work with Jersey v2.5+:

final ClientConfig config = new ClientConfig();

config.property(ClientProperties.PROXY_URI, "http://myproxy.com:8000");

CredentialsProvider credentialsProvider = new BasicCredentialsProvider();

final AuthScope ntlmAuthScope =
        new AuthScope("myproxy.com", 8000, AuthScope.ANY_REALM, "NTLM");

credentialsProvider.setCredentials(
        ntlmAuthScope,
        new NTCredentials("user", "password", "hostname", "domain") );

config.property(
        ApacheClientProperties.CREDENTIALS_PROVIDER, credentialsProvider);

config.connectorProvider(new ApacheConnectorProvider());

Client client = ClientBuilder.newClient(config);

Please note: I am using the Apache HttpClient connector with Jersey Client - you may require slightly different code if you are using another client transport connector.

You may also need to add the following line to your code if you want your POST/PUT requests to be buffered (and therefore repeatable) in response to any 407 authentication challenges that come back from your proxy server:

config.property(ClientProperties.REQUEST_ENTITY_PROCESSING,
                RequestEntityProcessing.BUFFERED);
