Download AJAX generated content using java

I have a webpage on which a list of movies is being displayed. The content is created using AJAX (as far as my limited knowledge would suggest...).

I want to download the content, in this case the movie playing times, using Java. I know how to download a simple website, but here my solution only gives me the following as an result instead of the playing times:

ajaxpage('http://ift.tt/1D0IccR', "kinoprogramm");

How do I make my program download the results this AJAX function gives?

Here is the code I use:

        String line = "";
        URL myUrl = http://ift.tt/1BEJ9De;
        BufferedReader in = null;
        try {
            myUrl = new URL(URL);
            in = new BufferedReader(new InputStreamReader(myUrl.openStream()));

            while ((line = in.readLine()) != null) {
                System.out.println(line);
            }
        } finally {
            if (in != null) {
                in.close();
            }
        }
