You only take column class from column 0, next in for-loop class is tb.getColumnClass(i) but all column classes are the same so the same renderer will be used everywhere. Check what will happen when You put tb.setDefaultRenderer(tb.getColumnClass(0),renderer_right); after for-loop.>

Wow! It's works. thanks a million:thumbup:

I recall that it was a fairly big thing a few years back, but ever since Java EE 5 went with using ORM tools such as Hibernate for JPA, JDO seems to disappeared. Are you sure you want to learn a technology that is pretty much deprecated?

Thanks for reply.
What's your suggestion?
hibernate? and what 's the best resource to learn?

Yes I read it before, I don't have any problem with jdbc.

I should consider a computer as server that keeps database and another computers should be connected to that server via network (a local network like an office not internet) and they perform some ordinary tasks like inserting,updating,...

Hi java programers

How can I change keyboard layout in textfields?

Hi guys
I would like to have same font in all of my java app, I know the way is synth. I tried this code :
SynthLookAndFeel laf = new SynthLookAndFeel(); laf.load(main.class.getResourceAsStream("a.xml"), main.class); UIManager.setLookAndFeel(laf);
<?xml version="1.0" encoding="UTF-8"?> <synth> <style id="x"> <opaque value="true"/> <font name="Arial" size="12"/> </style> <bind style="x" type="region" key="*."/> </synth>

you know the font changes but all of my JInternalFrame and their contents and everythings disappear!
just my jmenu is visibale without any border. any idea?!

Hi guys
I have a jtable that I want some columns have right aligment and some of them have center. When I use this code:
DefaultTableCellRenderer renderer_right = new DefaultTableCellRenderer(); renderer_right.setHorizontalAlignment(JLabel.RIGHT); tb.setDefaultRenderer(tb.getColumnClass(0),renderer_right); DefaultTableCellRenderer renderer_center = new DefaultTableCellRenderer(); renderer_center.setHorizontalAlignment(JLabel.CENTER); for (int i=1; i<tb.getColumnCount();i++) tb.setDefaultRenderer(tb.getColumnClass(i), renderer_center);
All of my columns get CENTER aligment!
What's the problem?
regards
