Hi guys, I am having difficulty trying to debug this exception....

My swing apps, retrieves record from Database and is wrapped by a TableModel.
Finally this is passed into a JTable.

Finally this app is multi-thread, meaning it can accept multiple database queries and repaint the same Jtable once the query is completed.

please help. thanks.

Hi guys,

I have a JSwing frame that queries a database and spits out results in a JTable.
I have included a JProgressBar to monitor as each record is retrieved after a button is pressed.

So far the code works when i click on my button the first time, however subsequent button clicks the JProgressBar does not reset to 0.

heres some code:



Can anyone shed a light why the second time i click on retrive button the progressBar doest not reset to 0 and stays at 100%?

tks!
