which java http client library is easy to use for programmatically doing posts, setting cookies 开发者_Go百科and maybe ajax?

Apache HTTP Component (HttpClient 4.0),

http://hc.apache.org/httpcomponents-client-4.0.1/index.html

Normally, I would just use HttpURLConnection but its cookie handling is too weak to simulate browser behavior.

You can use JdkRequest from jcabi-http (I'm a developer), which does all this work for you, decorating HttpURLConnection, firing HTTP requests and parsing responses, for example:

new JdkRequest("http://www.google.com")
  .header("Content-Type", "application/x-www-form-urlencoded")
  .body()
  .formParam("name", "John")
  .back()
  .method("POST")
  .fetch();
