[Resteasy-users] [StreamingOutput]: ChunkedInputStream - Error parsing trailer headers (text format)

[Jean-Paul D. <jpd...@ci...>]

Hello,

I'm trying to use the StreamingOutput facility to send a server-side 
generated Pdf to a client.
When I'm decoding the client-sided InputStream I have a 
"ChunkedInputStream - Error parsing trailer headers" Exception

What am I missing ?
Help would be *very* appreciated,
JeP

SERVER SIDE
===========
  @POST
 @Path("/map2pdf")
 @Consumes("application/xml")
 @Produces("application/pdf")
 public StreamingOutput Map2PdfRestfulStreamingImpl(GetMap2Pdf msg) throws 
NamingException, IOException {
  return new Map2PdfStreamingOutput(msg);
 }

 /*
  * an inner class that implements the StreamingOutput interface
  */
 private class Map2PdfStreamingOutput implements StreamingOutput {
  GetMap2Pdf msg;

  public Map2PdfStreamingOutput(GetMap2Pdf msg) {
   this.msg = msg;
  }

  public void write(OutputStream output) throws IOException, 
WebApplicationException {
   ...............

   // -- response processing
   try {
    createPdfFacade.generatePDF(request, pdfSize0);
    ByteArrayOutputStream os = createPdfFacade.getOutputStream();
    os.writeTo(output);
    os.close();

   } catch (BusinessInputFault bif) {
    throw new WebApplicationException(bif, 
Response.Status.INTERNAL_SERVER_ERROR);
   }
  }
 }

CLIENT SIDE
===========
  // ==== RESTful HTTP call
  ClientExecutor clientExecutor = new ApacheHttpClientExecutor(new 
HttpClient(
    new MultiThreadedHttpConnectionManager()));
  ClientRequestFactory clientRequestFactory = new 
ClientRequestFactory(clientExecutor, new URI(map2PdfServer));
  ClientRequest request = clientRequestFactory.createRequest(map2PdfUrl);
  // RESTful content negotiation
  request.accept("application/pdf");
  request.body(MediaType.APPLICATION_XML, getMap2Pdf);

  // -- sends request
  ClientResponse<InputStream> response = request.post(InputStream.class);
  Integer status = response.getStatus();
  System.out.println("status: " + status);

  // gets HTTP headers
  MultivaluedMap<String, String> map = response.getHeaders();
  Set<String> keys = map.keySet();
  for (String key : keys)
   System.out.println("key: " + key + "\t value: " + map.get(key));

  // gets HTTP body content
  InputStream is = response.getEntity();

  // -- writes Pdf file
  String ext = curMedia.substring(curMedia.indexOf("/") + 1);
  writeToFile(is, ext + "_" + extension);
