Struts2: Ajax response not received sent by Result in jQuery

I send an Ajax request to an Action class and try to get the response from a Result.
Here is my jQuery code: 

$('#button').click(function(){                    
            $.get('ajax.action','query="hi server:)")',function(x,r,s){                    
            alert("server said :"+r+"-stat-"+s.status);                    
            })

Here always the response is 'success' which not the expected response.
Here is my Action class's execute(). 

String response;
String query;
     @Override
    public String execute() throws Exception {

        response=query+" - Struts added :";        

        setResponse(response);

        return SUCCESS;
    }

There a getters and setter for string response and query have been written(not showed here).
Here is my Result class 

public class AjaxResponse implements Result {

@Override
public void execute(ActionInvocation ai) throws Exception {

    System.out.println("I am the Ajax Rsponse RESULT");// this is displayed in the console
     PrintWriter out =
                ServletActionContext.getResponse().getWriter();
    try {
        ServletActionContext.getResponse().setContentType("text/plain");

        ValueStack valueStack = ai.getStack();
       // Object resObj= valueStack.findValue("response");
        out.print("hi I am server ...");

        System.out.println("Response WROTE---");
    } catch (Exception e) {
        e.printStackTrace();

    }finally{

    out.close();
        System.out.println("Response Close "); // this is displayed in the console
    }        
}

}

Here is how I added my Result class to struts.xml 

 <result-types>        
        <result-type name="ajaxResponse" class="com.app.ajax.AjaxResponse" />  
 </result-types>

Here is how I declared the action 

<action name="ajax" class="com.app.action.AjaxSupport">
        <result type="ajaxResponse"/>
    </action>

The alert always gives only SUCCESS , not the expected result 'hi I am server ...' .
The console displays the Result class's prints-("I am the Ajax Response RESULT","Response WROTE---","Response Close") I used a separate Result class for loose couple the task and do the business logic inside the action class.
Please any one let me know where my problem is ?

Problem is in not in Struts but where I check the result whether it s right or wrong. 

$.get('ajax.action', 'query="hi server")', function(x, r, s) {                    
    alert("server said: " + r + "-stat-" + s.status);

According to this alert, the output is:

server said: success-stat-200

Problem was seeing this success . confused with callback function's parameters.

Here 'r' is status of the response (I'd thought the response), s is xmlHttpRequest object.

I had to check not r, but x which is real expected value. Printing x's value, the real value of what the server sent appeared.
