----------------------------------------------------
It seems related with my machine. I thought it was "clean", but it seems not.
> Incomplete data received from servlet

> Hi
> I have this servlet that generates on the fly a binary response by
> serializing an object. buf size is about 30 KB. I've been using this code to
> serve files for a long time. If I access that servlet using any web browser,
> the received file is OK.
> byte[] buf = respObject.stringBinSerialize();
> response.setContentLength(buf.length);
> response.setContentType("binary/octet-stream");
> response.setStatus(HttpServletResponse.SC_OK);
> OutputStream out = response.getOutputStream();
> out.write(buf);
> out.flush();
> Now I have this client code and it doesn't receive the full response.
> byte[] completo = new byte[0], temporal;
> byte[] cbuf = new byte[4096];
> int cuenta = 0, esta = 0;
> HttpParams params = new SyncBasicHttpParams();
> HttpConnectionParams.setSocketBufferSize(params, 64000);
> HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
> HttpClient httpclient = new DefaultHttpClient(params);
> try {
> HttpPost httpost = new HttpPost(targetURLinclServletName);
> HttpGet httpget = new
> HttpGet("http://localhost:8080/myservlet";);
> HttpResponse response = httpclient.execute(httpget);
> HttpEntity entity = response.getEntity();
> if (entity != null) {
> System.out.println("ent sz " +
> entity.getContentLength() + " chk " + entity.isChunked() + " is rept " +
> entity.isRepeatable() + " str " + entity.isStreaming());
> // completo = EntityUtils.toByteArray(entity);
> System.out.println("bytearrayed " + completo.length);
> InputStream instream = entity.getContent();
> while (completo.length != entity.getContentLength()
> && (esta = instream.read(cbuf)) != -1) {
> if (selector.equals(RPCdefs.SELECTOR_PROYLIST) ||
> true) {
> cuenta += esta;
> System.out.println("readline" + esta + " van
> " + cuenta);
> System.out.println("sz " +
> entity.getContentLength());
> }
> temporal = new byte[completo.length + esta];
> System.arraycopy(completo, 0, temporal, 0,
> completo.length);
> System.arraycopy(cbuf, 0, temporal,
> completo.length, esta);
> completo = temporal;
> temporal = null;
> }
> }
> EntityUtils.consume(entity);
> } finally {
> httpclient.getConnectionManager().shutdown();
> }
> The simplest way to receive is EntityUtils.toByteArray(entity), but it gets
> hung. The loop for partial copy is to know how may bytes are received. They
> are about 17845. The initial params were added to check if the issue was
> related to flow control, but with 64 KB buffers it doesn't changes anything.
