JTextfield Listeners

Hello,

I have a JTable with DefaultCellEditor set to JTextfield for all the cells.what kind of listeners should I use so that when I click a particular cell that has the Column Header as "validFrom" ,should show me a calendar(from other class) so that I can choose a date from this calendar to set in this cell of the JTable.

Please help.
