I am trying to display a result set from an Oracle database in a JTable.
The isCellEditable() method returns true for all cells in this table.

I find that the cells are editable if the column type in the database is
varchar2 and number data types,  If the column type is java.sql.Date, the
cell is not editable.
 If however I create java.util.Date objects within the program, the table
cells are editable for these objects.

Why is this so?  I am now working around this by converting the date
information to String before displaying in the table.  But I would prefer a
more elegant method, if someone can show me.

Thanks

The default editor lookup mechanism requires an exact match on the
class - it will not find an editor for a subclass.  What you need to do
is to define the default editor for the java.sql.Date class.  I think
you should be able to get the default editor for the java.util.Date
class and use that.
