Java EE (Java Enterprise Edition) General Discussion

I have been trying to create an XML doc using jaxb, and sending that xml file through a socket to a client where to XML file would be created and also it would be unmarshaled and have its content printed on the screen. The thing is that I can not get the values if the child elements like DAint printed out and I not sure what to do. Please help!!!!!

For the output I get the values of the id, and is alert, but I can't get the values from getDataEvents().

Here is the server

             // GET THE jaxb CONTEXT OBJECT
             JAXBContext jaxbCtx = JAXBContext.newInstance("osacbmx");

             // CREATES THE MARSHALLER
             Marshaller marshaller = jaxbCtx.createMarshaller();

            // THE OBJECTfACTORY CLASS IS CREATED
             ObjectFactory objFactory = new ObjectFactory();

             // OTHER OBJECTS

             OsacbmTime time = new OsacbmTime();
             time.setTime("5.00");

             Site site = new Site();
             site.setSiteId("Site1");

             // THE DATA EVENT SET OBJECT IS CREATED
             DAReal dareal = new DAReal();
             dareal.setValue(21.23);
             
             DAInt daint = new DAInt();
             daint.setValue(21);
             
             DAString dastring = new DAString();
             dastring.setValue("Steven Romero");
             
             DABool dabool = new DABool();
             dabool.setValue(true);
             
             DAVector davector = new DAVector();
             davector.setXValue(45);
             
             DAString dastring1 = new DAString();
             dastring1.setValue("Applied Research Labs");

            

             List waveForm = new ArrayList();
             waveForm.add(121.54);
             waveForm.add(12.3);
             waveForm.add(45.5);
             waveForm.add(23.45);

            
             DAWaveform dawaveform = new DAWaveform();
             dawaveform.setId(good);
             dawaveform.setConfid(24.55);
             dawaveform.setTime(time);
             dawaveform.setSite(site);




        byte[] myByteArray = { (byte)2, (byte)3, (byte)41 };


             
             dawaveform.setValuesBinary(myByteArray);
             dawaveform.getValues().addAll(waveForm);


             DADataSeq dadataseq = new DADataSeq();
             dadataseq.setSequenceNum(good);
             dadataseq.setConfid(23.456);
             dadataseq.setTime(time);
             dadataseq.setSite(site);
            
             


             
             // data event object created
             DataEventSet dataEvent = new DataEventSet();

             dataEvent.setAlertStatus(java.lang.Boolean.TRUE);

             dataEvent.setId(goods);

             ArrayList<DataEvent> data = new ArrayList<DataEvent>();
             data.add(daint);
             data.add(dareal);
             data.add(dastring);
             data.add(dabool);
             data.add(davector);
             data.add(dastring1);
             data.add(dawaveform);
             data.add(dadataseq);

             dataEvent.getDataEvents().addAll(data);


   

             // THE JAXBELEMENT DATAEVENTSET IS CREATED
             JAXBElement <DataEventSet> xElement = objFactory.createDataEventSet(dataEvent);

             marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT ,
                   new java.lang.Boolean(true));

             // DataEvenSet marshalled then sent through the socket.
             marshaller.marshal( xElement, socket.getOutputStream() );
             System.out.println("the xml file has been created and sent to the client");

             socket.shutdownOutput(); // send EOS

             socket.close();


            }catch(Exception e){ e.getMessage();}

    }

   public void createConnection()
   {
        try {
            serverSocket = new ServerSocket(100);
            System.out.println("OSACBM server running ...");

            } catch (IOException e)
            {
            System.err.println(e.getMessage());
            System.exit(1);
            }
   }
}

Here are classes involved with the server.

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "DataEventSet", propOrder = {
    "alertStatus",
    "dataEvents",
    "id",

    }

     *     
     */
    public void setAlertStatus(java.lang.Boolean value) {
        this.alertStatus = value;
    }

    /**

    public List<DataEvent> getDataEvents() {
        if (dataEvents == null) {
            dataEvents = new ArrayList<DataEvent>();
        }
        return this.dataEvents;
    }

Here is part of the client side that wont work.

             JAXBContext jaxbCtx = JAXBContext.newInstance("osacbmx");

             Unmarshaller u = jaxbCtx.createUnmarshaller();
             System.out.println("new.xml has been recieved and unmarshalled");

             JAXBElement <DataEventSet> element1 = u.unmarshal(new StreamSource("new.xml"),DataEventSet.class);

             DataEventSet dataEvent = element1.getValue();
\
 for (int i = 0; i < dataEvent.getDataEvents().toArray().length; i++) {
			System.out.println("The Attribute are " + (i + 1) + ": "
					+ dataEvent.getDataEvents().get(i)
					);
		}
            System.out.println(dataEvent.isAlertStatus());
             System.out.println(dataEvent.getId());
//             System.out.println("The values for the DataEventSet XML are \n " +(DataEvent)dataEvent.getDataEvents());

            }catch(Exception e){System.err.println(e.getMessage());}

     }code}
