Hello,

Im trying to create a "Header" for my JTable by using .setModel()...


But the problem is that it doesn't work.. My Jtable gets it's data from Db and when I run it the .setModel() hides the data from Dd. After my function Update() the data will show up.

This s my code for getting the data from my db:


try {
			ResultSet result = statement.executeQuery("SELECT * FROM devices");
			java.sql.ResultSetMetaData md = result.getMetaData();
			int columnCount = md.getColumnCount();
 
			colums = new Vector(columnCount);
 
			for(int i=1;i<=columnCount;i++){
				colums.add(md.getColumnCount());
 
 
			}
 
			data = new Vector();
 
 
			while(result.next()){
				Vector row = new Vector(columnCount);
				for(int i=1;i<=columnCount;i++){
					row.add(result.getString(i));
				}
				data.add(row);
 
			}
 
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
Code for creating JTable and .setModel()

table = new JTable(data,colums);
		[ATTACH=CONFIG]1427[/ATTACH]
		table.setModel(new DefaultTableModel(
			new Object[][] {
				{null, null, null},
				{null, null, null},
				{null, null, null},
				{null, null, null},
				{null, null, null},
				{null, null, null},
				{null, null, null},
				{null, null, null},
				{null, null, null},
				{null, null, null},
				{null, null, null},
				{null, null, null},
			},
			new String[] {
				"Device Name", "Device State", "Id"
			}
		));
 
 
		getContentPane().add(table);


My update function: 
protected void Update_Table() {
					// TODO Auto-generated method stub
					try{
						String update = "SELECT * FROM devices";
					//	statUp = (Statement) con.createStatement(update);
						ResultSet rest = statUp.executeQuery(update);
						//table.setModel(DbUtils.updateTableModel(rest));
						table.setModel(DbUtils.resultSetToTableModel(rest));
 
						//DbUtils.
					}
					catch(Exception ex){
						ex.printStackTrace();
						JOptionPane.showInputDialog(null, "Couldn't create new Device");
					}
				}
This is the first problem.

Second problem is that even like this the name of the columns doesnt appear.

Can you please help me?

Thank you
