Problem on JScrollPane

Question

I'm trying to put some JLabel to a JPanel and then put it into a JScrollPane but somehow I dont see any JScrollBar appear anywhere...is there something wrong that I did?Or do I have to manually set a scrollbar ?.. I have try manually put in one but still got the same result...I did read some example on it but it works for them, when I try to do the exactly the same thing in my code...it fails....
JLabel a = new JLabel("a");
JLabel b = new JLabel("b");
JLabel c = new JLabel("c");
JPanel contain = new JPanel(new GridLayout(3,1));
contain.add(a);
contain.add(b);
contain.add(c);
JScrollPane AScroll = new JScrollPane()
AScroll.add(contain);thx for the help

Answer 1

First of all, thank you for your suggetion..
After I try your method of doing it..I still get the same result...Here is my actual code..
          NewLayout = new GridLayout(2 * NumOfRiding,2);
          NewLayout.setVgap(4);
          InfoTextPanel.setLayout(NewLayout);
          InfoTextPanel.setBorder(BorderFactory.createEmptyBorder(10,0,0,0));
          for(int i = 0; i < NumOfRiding; i++){
               CandNameLabel = new JLabel("Canditate " + (i+1) + " Name");
               InfoTextPanel.add(CandNameLabel);    //first label add into infotextpanel
               CandNameText = new JTextField(10);     
               CandVector.add(CandNameText);
               InfoTextPanel.add(CandNameText);     //a TextField add into infotextpanel
               PartyLabel = new JLabel("Party");
               InfoTextPanel.add(PartyLabel);          //another label add into a infotextpanel
               PartyNameList = new JComboBox(PartyName);
               CandPartyVector.add(PartyNameList);
               InfoTextPanel.add(PartyNameList);     //a combobox added into the infotextpanel
               InfoPanel.add(InfoTextPanel);          //the infoTextPanel is add into InfoPanel so more InfoTexPanel add be added
          JScrollPane AScroll = new JScrollPane();
          AScroll.setViewportView(InfoPanel);And After this.. I have to put this scrollpane into another panel and then into the actual windows...
