RussianQuestion
i am having trouble finding out problem in my jtable sorting mechanism ,when ever i implement sorting inside the search code it gives me array index out of bounds , the populate table code works fine at intial stage but after the search happens it is also stuck.
My application has a text field area which accepts keywords for searching from database. Now after searching ,it displays it on jtable and i want to provide table sorter for that. Any help is appreciated . thks . I have also provides the stack trace below.
//problem code
// for searching data from data base and display it in table
// according to the keyword typed.
private void jTextField1KeyPressed(java.awt.event.KeyEvent evt) {
System.out.println(evt.getKeyCode());

Solution
First, please don't use KeyListeners, if you want this kind of action, use an ActionListener - there are 100's of reasons why, but for now, just trust us ;)
Try setting the sorter to null before changing the model
jTable1.setRowSorter(null);
I've usually encountered this problem due to a mutation event cause by multiple threads trying to update the model out of sync.
OTHER TIPS
Digging a bit (as always when I have the time and something puzzles me :-)
First: @MadProgrammer's answer is correct - iff the client code takes responsibility to keep sorter and model in synch itself, instead of delegating that burden to the table.
Client code taking the burden:
TableModel model = .. //create some model;
table.setModel(model);
table.setRowSorter(new TableRowSorter(model));
// has to remove the rowSorter _before_ setting a new model
// because the old rowSorter still references the old model
table.setRowSorter(null);
TableModel newModel = ... // create some model ;
table.setModel(newModel);
table.setRowSorter(new TableRowSorter(newModel);
Let the table take care:
table.setAutoCreateRowSorter();
TableModel model = .. //create some model;
table.setModel(model);
// nothing to fear, simply set the new
TableModel newModel = ... // create some model ;
table.setModel(newModel);
BTW: in the OP's context, there is no need to reset the model - it's basically the same, just different data. So
// initially setting the model and rowSorter (in populate)
...
// in re-populating, instead of re-creating the same model
//table.setModel(newModel);
// clear
((DefaultTableModel) table.getModel()).setRowCount(0);
...
// and - while we are at it - cleanup the logic
while(result.next()) {
Object[] rowData = {result.getInt("emp_id"),
result.getString("emp_name"), result.getString("emp_address")};
((DefaultTableModel) jTable1.getModel()).addRow(rowData);
}
