Jtable Cell editing validations

[Rambo Rambabu]

Hi, I need to validate values entered into a table cell. I need to see if the entered value is atleast 7 chars and call a validation method. I need to do these validations as soon as 7 chars are entred. I tried extending CellEditorListener for my adaptor, but editingStopped metohd is firing only after I leave the cell and since I allready left the cell, I don't know how to get the value in the just edited cell as getEditingColumn is giving me -1 in the editingStopped Method.
Also, when user presses the SAVE button, I need to verify if any values are changed for the table (Only one column is editable) and fire a correpsonding save method.
Thak you for your help...

You must use a JTextField with your own DocumentModel which can take control of all inputs just in time.
You must specify an editor like this:
e.g.
JTextField tf2 = new JTextField(yourDocumentModel,null,0);
tf2.setHorizontalAlignment(JTextField.RIGHT);
TableCellEditor editor = new DefaultCellEditor(tf2);
