HI Keerthi

On a first look at the code and error , I could see a line in the error log which says service: Resource /bin/moviename not found . Did you verify if the bundle is active ?

Thanks

Hi Keerthi

Can you provide your sample code. This could clearly be issue with your code.

Thanks

Here is the code :

@Service(ListOfMovies.class)

@SlingServlet(paths = {"/bin/moviename"}, generateComponent = false)

@Component(label = "Dropdown Movie data provider", description = "This servlet provides list of movie names in drop down",

enabled = true, immediate = true, metatype = false)

public class ListOfMovies extends SlingSafeMethodsServlet {

private static final Logger LOGGER = LoggerFactory.getLogger(ListOfIPs.class);

@Override

protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) {

try {

JSONObject eachOption;

JSONArray optionsArray = new JSONArray();

String[] movies = { "Terminator", "Kicking & Screaming","Harold and Maude",

"Ratatouille", "10 Things I Hate About You", "American Beauty",

"The Dark Knight", "The Wolf of Wall Street","Mean Girls",

"Inception", "Life Is Beautiful", "No Country for Old Men" };

String[] returnData = new String[movies.length];

for (int i = 0; i < movies.length; i++) {

eachOption = new JSONObject();

returnData[i] = movies[i];

eachOption.put("text", returnData[i]);

eachOption.put("value", returnData[i]);

optionsArray.put(eachOption);

}

JSONObject finalJsonResponse = new JSONObject();

//Adding this finalJsonResponse object to showcase optionsRoot property functionality

finalJsonResponse.put("root", optionsArray);

response.getWriter().println(finalJsonResponse.toString());

} catch (JSONException e) {

LOGGER.error("Json Exception occured while adding data to JSON Object : ", e);

} catch (IOException e) {

LOGGER.error("IOException occured while getting Print Writer from SlingServletResponse : ", e);

}

and deployed through maven. In log,
