you need to understand your config file first ,

<result type="stream">
        <param name="contentType">text/html</param>
        <param name="inputName">inputStream</param>
    </result>

means the response is expecting a "text/html" type response and the parameter inputName has a stream variable by name "inputStream" with getters and setters , that inputStream is what you should be sending in response .

create a variable by name "inputStream" of data type say InputStream with getters and setters and then return SUCCESS .

in ajax , put an error field , like this :

$.ajax({
         type   :  "POST",
         url    :  "action",
         data   :  Data,
         encode :  true,
         error  :  function(){
             what should happen on error , if ajax call itself failed to specified url.
         }
      }).done(function(status){ 
         what should happen after successful response
        })
