it is strange that my code was working before I modified some variable name/ type. i didn't make any major changes except for changing from double to int, and from double to String. the change was involved a bit sql code change as well though.


i got (does anyone have any clue what possibly went wrong?)

Like In?

I don't think that could ever work.

huh, good catch. however, i never really used that variable... i will fix that though. thanks.

however, the major problem is still being the sql exception.

That "class" however, is not doing any SQL. You need to provide the DataHolder class. Also, currently you are doing your work on the event thread which is more than just wrong. You need to learn about MVC and use it. At the very least, you need to completely separate your DB and GUI code and do the actual DB work in a separate thread that then triggers an update of the GUI.

thanks very much for your opinion. i am actually working on improving the code of this program. I wrote this program last year. anyway, i just looked over the DataHolder class and found a small mistake causing the sql exception. Thanks very much.
