How to return a JSON Array from java server to ios app

Question

I has an ios app which sends a http request to a REST service I have running on a local server. The server gets some information from the Twitter api and then sends it back to the ios app. I have put the data I want to send back in a JSONArray. How do I go about sending this array back as a response to the request.

I have included the method that receives the request and which initially sent back a string. I would like to change so it sends back the "returnedArray" array instead.

@Path("/hello")
public class HelloResource {

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String sayHello() throws JSONException {
        String convert = null;
        JSONArray returnedArray = new JSONArray();

        try {
            returnedArray = TweetUsingTwitter4jExample.getTweets();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (TwitterException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return convert;
    }
}

在JSONArray上调用toString() 。
