Jtable + listbox + Date

Question

1)We're using a Jtable to make a reservation and when a user clicks on a square in the Jtable(grid), he should get a form to fill in and afterwards his name will be filled in to the selected square in the Jtable(grid). Does anybody know the code to do this?
This Jtable(grid) opens in a separate window and we'd like it to open in the regular window, how can we do this?
2)Does anybody know how you can change the date. f.e. I want to change the current date into the date of the last week when I push on a button. I don't know how??
3)What is the code to make a listbox which uses the data in an access database?
Could we get this in regular java code, not javascript, thanks!

Answer 1

You won't get much JavaScript round here anyway!
That's quite a lot of questions you've got there.
1) This would depend partly on how you're storing the data for the cells. However, to get a window to pop up when you click on a cell you need to write a custom TableCellEditor. There's an example of how to do this in the Swing section of the Java Tutorial. Your custom editor should simply create a new modal dialog and retrieve the values from it once it is closed.
2) To manipulate dates you need to use the Calendar class. For example, to change a date back a week you'd do something like this:
Calendar calendar = calendar.getInstance();
calendar.setTime(date);
calendar.add(Calendar.DAY, -7); // go back seven days
Date newDate = calendar.getTime();3) If you're able to connect to your access database then it will be as simple as writing an SQL query for it and reading the values back in to a JList.
Connection conn = null;
Statement stmt = null;
try
  conn = DriverManager.getConnection("jdbc:odbc:MyDataSource");
  stmt = conn.createStatement();
  ResultSet rs = stmt.executeQuery("SELECT name FROM my_table ORDER BY name");
  list.removeAllItems();
  while(rs.next())
    list.addItem(rs.getString(1));
finally
  // close statement and connection
}The example I've given here assumes you've set your Access database up as an ODBC datasource called "MyDataSource".
Have a look in the JDBC forums for more examples of how to connect to Access and read data back.
Hope this helps.
