title: Authentication and authorization for RESTfull API (java jersery)
body: <p>implementing service something similar with tinyurl or bit.ly, I'm would like to expose service as API, I'm using java and jersey as RESTfull service implementation. </p>
  
  <p>I'm looking for simplest way for authentification of users who use API, OAuth is first thing coming in mind, but the problem is I don't need this 3 iteration calls with request token query, than access token query with callback url passing. I just need to give user ability to invoke api with no additional security calls to my server.</p>
