Jtable sorting; problem with getValueAt

[Peter Primrose]

Hi guys,

I have implimeneted a sorting JTree (with a TableSorter).
Problem is when the user clicks on the column, say length, the sorting is incorrect. (it sorts it as if it's a String; same goes to the sort by dueDate)

I understand that the sorting is according to the object's type. the due date is a String in the example below but when converting to Date, the result is: Wed Aug 10 00:00:00 PDT 2005) (?!)

anyone knows how to correct this?
Thanks
Peter

 public Object getValueAt(int row, int col) 
{   
   InsuredPax ip = (InsuredPax) model.elementAt(row);
   
   String fname = ip.getFirstName();
   String lname = ip.getLastName();
   int length = ip.getLength();
   String dueDate = ip.getDueDate();
 
   switch(col)
   { 
 case 0: return fname.toUpperCase();
 case 1: return lname.toUpperCase();
 case 2: return new Integer(length);
 case 3: return dueDate;
 default: return "Error"; 
   }
}

Which table sorter are you using? I guess the one
from the JFC demo is the most common, but there
are a few out there.

Also, what are you doing in your implementation
of the getColumnClass() method?

[Peter Primrose]

public String getColumnName(int column)
{
return names[column].toString();
}

protected TableModel dataModel = new AbstractTableModel()...
TableSorter sorter = new TableSorter(dataModel);

I asked about getColumnClass(), not getColumnName().

[Peter Primrose]

mmm, good question. I didn't implement it.
is this the source of the problem?

what should be returned?

public Class getColumnClass(int col)
{

}
