What is supported? All basic functionality (simple requests with or without entity) and Jersey related things like filters (logging, auth, ...). Additionally, some of Apache HTTP Client features are supported by default - like cookies processing.
What needs to be done:
How can you give it a try? Simply.. put another dependency to your maven project:
And create your client like:
Client c = new com.sun.jersey.client.apache.ApacheHttpClient4();
WebResource wr = c.resource("http://localhost:9998/helloworld-webapp");
String s = wr.path("helloworld").get(String.class);
and use it like you are used to..
