Hi,

I am developing an application using java swing. Here I retrieve data from database and show data on JTable by using AbstractTableModel. After got data in JTable, I have selected a row , it returns row no=-1.
Please help me to solve this problem.

Actually I am getting row no =-1 in table.getSelectedRow().

Thanks

First off, why do you use AbstractTableModel? Why not DefaultTableModel?

To get better help sooner, post a SSCCE that clearly demonstrates your problem.

Don't forget to use the code tags so your code retains its formatting.

Row selection has nothing to do with the TableModel, so it doesn't matter if it's an AbstractTableModel or DefaultTableModel. It's the JTable's ListSelectionModel that handles the selection.
