HttpClient Issue with InputStream

Question

Hi friends,
I am using HttpClient and here is my code -
To my surprise everytime I am getting similar response..everytime though my GUID value that I am passing is different.
InputStream respInputStream  = null;
          PostMethod post = null ;
          HttpClient httpClient = null;
          post = new PostMethod(strURL);
          try
               httpClient = ActuateConnectionManager.getHttpClient() ;
               // Create a method instance.
               post.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,new DefaultHttpMethodRetryHandler(2,false));
               post.addRequestHeader(GUID_KEY, GUID);
               httpClient.executeMethod(post);
               int statusCode = post.getStatusCode() ;
               if (statusCode != HttpStatus.SC_OK)
                    LoggerUtil.logAlert(AlertCode.INVALID_HTTP_STATUS_CODE);
                    LoggerUtil.logError(LogCategory.ACTUATE_SERV_CATEGORY,HTTP_RESPOSE_STATUS + statusCode ) ;
                    LoggerUtil.logError(LogCategory.ACTUATE_SERV_CATEGORY,HTTP_RESPOSE_STATUS_TEXT + post.getStatusText() ) ;
                    throw new AdvException(AdvErrorCode.INVALID_HTTP_STATUS_CODE) ;
               respInputStream = post.getResponseBodyAsStream();
                                               return respInputStream;
          catch( HttpException httpException )
               LoggerUtil.logAlert(AlertCode.HTTP_EXCEPTION);
               throw new AdvException(AdvErrorCode.HTTP_EXCEPTION, httpException);
          catch( ConnectTimeoutException connectTimeoutException)
               LoggerUtil.logAlert(AlertCode.CONNECTION_TIME_OUT) ;
               throw new AdvException(AdvErrorCode.CONNECTION_TIME_OUT,connectTimeoutException) ;
          catch( SocketTimeoutException socketTimeoutException)
               LoggerUtil.logAlert(AlertCode.READ_TIME_OUT) ;
               throw new AdvException(AdvErrorCode.READ_TIME_OUT,socketTimeoutException) ;
          catch( IOException ioException )
               LoggerUtil.logAlert(AlertCode.HTTP_CLIENT_IO_EXCEPTION);
               throw new AdvException(AdvErrorCode.HTTP_CLIENT_IO_EXCEPTION, ioException);
          finally {
                                         respInputStream.close();
                                         post.close();
     }I am also using ConnectionManager - which returns me HttpClient object.

Answer 1

and one more observation to my surprise,
if I just replace the HttpClient code with below given code, then my program works absolutely fine.
DataInputStream smartOfficeIS = null ;
          HttpURLConnection connection = null ;
          String line = null ;
          System.out.println( "Getting Connection ...") ;
          URL url = new URL(strURL);
          URLConnection uc = url.openConnection();
          connection = (HttpURLConnection) uc;
          uc.addRequestProperty("SMUNIVERSALID", GUID) ;
          connection.setDoOutput(true) ; //able to read from the connection
          //Reading the data from the smart integrator
          smartOfficeIS = new DataInputStream(new BufferedInputStream( connection.getInputStream()));
          while( ( line = smartOfficeIS.readLine() ) != null ){
             System.out.println( line ) ;
          }can somebody help me please..!!
I am totally lost.
