Jersey request.getInputStream()

@POST
@Path("/getphotos")
@Produces(MediaType.TEXT_HTML)
public String getPhotos() throws IOException{
    BufferedReader rd = new BufferedReader(new InputStreamReader(request.getInputStream(),"UTF-8"));
    String line;
    while ((line = rd.readLine()) != null) {
        System.out.println(line);
    }
    return "ok";        
}

The code above is for my server. But in this code, the String "line" has no value.(always) Is there any problem with the code?

client side code

    String message = "message";
    URL url = new URL(targetURL);
    HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

    urlConnection.setDoInput(true);
    urlConnection.setDoOutput(true);
    OutputStreamWriter wr = new OutputStreamWriter(urlConnection.getOutputStream());
    wr.write(message);

You can manually consume a request's data in Jersey, as long as you have a valid handle to the actual HttpServletRequest. On a slight side note, keep in mind that you can only consume the request body once:

@Context
private HttpServletRequest request;

@POST
@Path("/")
public Response consumeRequest() {
    try {
        final BufferedReader rd = new BufferedReader(new InputStreamReader(
                request.getInputStream(), "UTF-8"));

        String line = null;
        final StringBuffer buffer = new StringBuffer(2048);

        while ((line = rd.readLine()) != null) {
            buffer.append(line);
        }
        final String data = buffer.toString();
        return Response.ok().entity(data).build();
    } catch (final Exception e) {
        return Response.status(Status.BAD_REQUEST)
                .entity("No data supplied").build();
    }
}

Side note: Libraries like Apache Commons IO provide robust functions for reading IO data
