JTableHeader + columns

Question

Hello to all!!!!!
I speak spanish
I am working with a jTable in which the idea is to take information from a DB and to show it by this component. But it is that the columns of the table can be changed of position and be changed the size of them. So that this does not happen I read in the API in the JTableHeader class the methods setReorderingAllowed() and setResizingAllowed() which handle this, but I can?t to know, of how they are used since I have proven several forms and throws errors, this is what I make:
TableModel dataModel = new AbstractTableModel() {
final String[ ] columnNames = { "Name", "Last name", "Pastime", "Years of Practices", "Soltero(a)" };
Object[][ end ] dates = {
{ "Mary", "Campione"," To ski ", new Integer(5), new Boolean(false) },
{ "Lhucas", "Huml"," To slide ", new Integer(3), new Boolean(true) },
{ "Kathya", "Walrath"," To climb ", new Integer(2), new Boolean(false) },
{ "Marcus", "Andrews"," To run ", new Integer(7), new Boolean(true) },
{ "Angela", "Lalth"," To swim ", new Integer(4), new Boolean(false) } };
public int getColumnCount() { return columnNames.length; }
public int getRowCount() { return data.length; }
public String getColumnName(int col) { return columnNames[col ]; }
public Object getValueAt(int row, int col) { return data[row][col ]; }
public Class getColumnClass(int c) { return getValueAt(0, c).getClass(); }
JTable jTable1 = new JTable(dataModel);
JTableHeader to tableheader = jTable1.getTableHeader(); tableheader.setReorderingAllowed(false);
JScrollPane jScrollPane1 = JTable.createScrollPaneForTable(jTable1);
and the other form is to change:
JTableHeader to tableheader = jTable1.getTableHeader(); tableheader.setReorderingAllowed(false);
By:
jTable1.getTableHeader().setReorderingAllowed(false);
With first it throws the following error to me:
invalid method declaration; return type required and illegal start of type.
With second form: malformed passes + the same expression.
In addition, I am working with JBuilder2, that comes with JDK 1.1
How work these metodos and the JTableHeader class, Will be problem of my JDK of which it does not allow east type me of declarations? Why it throws these errors to me? Who me can throw a hand, beforehand many thanks.

I attempted to use Darryl's Default Table Header Cell Renderer, but I was unable (it requires java 1.6).
I modified the code to make a very simple renderer. It does the job apropriately, but the header cell does not change its color (to red or white) unless the window is resized. Here is my very simple renderer (based on Darryl's one). What am I missing now?
Thanks once more,
Federico
public class MyDefaultTableHeaderCellRenderer extends DefaultTableCellRenderer {
     public String jorl = "hola";
     public boolean tmp = false;
     public MyDefaultTableHeaderCellRenderer() {
          setHorizontalAlignment(CENTER);
          setHorizontalTextPosition(LEFT);
          setOpaque(true);
     public Component getTableCellRendererComponent(JTable table, Object value,
                                                               boolean isSelected, boolean hasFocus, int row, int column) {
          super.getTableCellRendererComponent(table, value,
                                                       isSelected, hasFocus, row, column);
          if(table.isColumnSelected(column)) {
               setBackground(java.awt.Color.red.darker());
          } else {
               setBackground(java.awt.Color.white);
          setBorder(UIManager.getBorder("TableHeader.cellBorder"));
          return this;
}
