I've resolved. I stupidly hide jsp lines using html comment tag.

Thanks for the help!

Yes, there is. What surprises me is, when i copied the lines(code) that has struts part to another file, save it, the file runs perfectly.

Any idea?

What could be the possible reason of the errors below? I made a very simple jsp application that uses struts own html tag library and it prompts me these errors. While, i copied the part of the code that uses struts to another file, it works ok.

thanks for the help.

You think so?
In the book, it uses Struts1.1 but what i have is Struts2.2. I couldn't find in jakarta site of the older version. I couldn't move on in my study because of these errors.

Anymore help who had this book?

Thanks!

Im trying to print a graphics. Almost done until i noticed a discrepancy whenever it loops. More loops, the discrepancy widens. Please see my code below. Thanks in advance!

Have it pop-up until you verified the value of the session variable.

Really need your help guys, im working on this for days now. I created sort of mock up of what im really actually doing. Im really working on a Table and a Spit Pane. Just to present to you as brief as possible i wrote a two table instead. The real issue is I can't seems to resolve on repainting a panel. The buttons are located in another class, while the panel to repaint is in separate class. When i click a the button one, it should present the table one and button two on table two. .

I really appreciate any help. Here are the codes of 3 classes. You may ignore the table model method below

There actually 2 panels and a frame involved(3 classes). There is CenterPanel that should be repainted. But the button that will trigger repaint is in SouthPanel. You almost had it.

So how? Thanks again!

Im new to GUI and having problem on repainting a panel.

I have 4 classes. Namely, MainFrame(JFrame subclass), NorthPanel(JPanel), CenterPanel(JPanel) and SouthPanel(JPanel).

MainFrame holds the 3 panels(classes) in a BorderLayout.
Now, SouthPanel has a button and an action listener that suppose to repaint the CenterPanel. So how would i call it or repaint repaint the CenterPanel inside the MainFrame? And where should i call the repaint?

I know this is really simple to you guys. Thanks in advance!

Thanks!
