My tree contains some 8 columns.Each column has an individual combobox. In this i need only one column to be editable, i mean values in one combobox alone must be editable. On submit button., all these values must be sent to db. I need your help in the first part., having individual combobox in JTable, editable combobox in one column alone.

Thanks in Advance.

I can't help but think that this question is in the wrong forum. Is this question about JSF?

JTree is a Swing component. It doesn't have "columns" so the first sentence is kind of nonsense, but then the rest starts talking about JTable, which does have columns. At any rate it doesn't seem to be about anything but Swing (definitely not Ant or Maven or any other build tool whatsoever) so I will move it to the Swing column.

It would also help if Dhivya could clarify the question so we at least knew whether it was about JTree or JTable.

very sorry., its JTable., each column in the JTable must have individual combobox in which one combo box is editable. for eg take combobox in the 5th column in the table is alone editable.

Check out how TableCellEditors work for the combo box. DefaultCellEditor can be used for this. Override isCellEditable of your TableModel to determine for each cell separately if it should be editable or not.
