Refresh a JTable from a JDBC connection

I have a Swing application that uses a JTable and JScrollPane to display data from an Access database via a JDBC connection.

Even though I had properly coded the SQL INSERT statement and the data was loading into my database, the JTable was not refreshing with the new record. I tried the .revalidate() and the .repaint() methods to no avail.

Finally, after reading Ben Hendry's Mastering JTable I was able to sort this out.

In my JButton ActionListener I added the TableModel.addRow method and inserted the newly inserted records into the JTable as well. Followed by a .revalidate() and the data properly displayed without even a flicker in my application.

Moral of the story - always use Model-View-Control (MVC) architecture and separate your view from your data and controls.
