title: OpenId authentication in struts 2 web application
body: <p>This is related to  OpenId authentication. 
  I have implemented the google and yahoo openId auth with java in struts2 
  but it is achieved through page redirection to openId provider auth page and then back to my own success web-page. 
  But what i wanted was same as facebook auth. were in json object is passed from fb and fb authentication is done in a pop-up. so that redirection can be avoided.
  Plz help me out.</p>
