why FIX fields using quickfix are null?

I am new to FIX. I have a FIX message: 

8=FIX.4.4|9=122|35=D|34=215|49=CLIENT12|52=20100225-19:41:57.316|56=B|1=Marcel|11=13346|21=1|40=2|44=5|54=1|59=0|60=20100225-19:39:52.020|10=072|

and I am using quickfixJ. Here is my class code:

    public String getYear(Message aMessage, SessionID aSessionID){
        try {
            crack(aMessage, aSessionID);
        } catch (Exception e) {
           e.printStackTrace();
        }

        String year = String.valueOf(mUTCCal.get(Calendar.YEAR));
        String begin = String.valueOf(BeginString);
        return year + " " + begin;
    }

and when I call this method I 2012 null I tried all sorts of methods for different fields and I get null. I am confused about why I do not get null for the date and how do I make it interpret correctly the other fields?

    quickfix.fix44.NewOrderSingle message;
    message = new quickfix.fix44.NewOrderSingle();
    SessionID session = new SessionID("beginString", "senderCompID", "targetCompID");
    MyApp app = new MyApp("", "", "");
    String result = app.myMessage(message, session);
    System.out.println(result);

I do not understand where to input the string I have (up top) into message

    public void onMessage(Message message, SessionID sessionID) throws FieldNotFound {
        Header header = message.getHeader();
        String FIX = header.getString(8);

        System.out.println(FIX);
    }

    public void onMessage(quickfix.fix44.NewOrderSingle message, SessionID sessionID) throws FieldNotFound, UnsupportedMessageType, IncorrectTagValue {
    Header header = message.getHeader();
    String FIX = header.getString(8);
            String a = message.getString(1);

            System.out.println(a);
            System.out.println(FIX);}

In order to correctly get and parse FIX messages via QuickFIX, you must:

The FromApp method can be very simple:

public void fromApp(Message message, SessionID sessionID)
{
  crack(message, sessionID);
}

Now, in your example you have a message FIX 4.4 of type 35=D [NewOrderSingle]

Therefore, you MUST implement a method as follows:

    public override void onMessage(QuickFix44.NewOrderSingle message, SessionID session)
    {
        base.onMessage(message, session);
    }

Now into your method you can easily work with all the fields you need:

    public override void onMessage(QuickFix44.NewOrderSingle message, SessionID session)
    {
        base.onMessage(message, session);

        ClOrdID ordid = new ClOrdID();
        message.get(ordid);
    }
