I'm devloping a java program using netbeans
I added a look and feel to GUI application which is Synthetica AluOxide Look and Feel from this website : http://www.javasoft.de/synthetica/themes/ .
I added the Synthetica.jar and syntheticaAluOxide.jar using Add Jar/Folder dialog o my project Libraries.
and then I added this code to my class load :
import de.javasoft.plaf.synthetica.SyntheticaAluOxideLookAndFeel;
.
.
.
try
{
UIManager.setLookAndFeel(new SyntheticaAluOxideLookAndFeel());
}
catch (Exception e)
{
e.printStackTrace();
}
but when I run my application I don't get any changes, and I get this error when I click on some component in my application :
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

Did you include Synthetica's core library 'synthetica.jar'
Ensure that your classpath contains all Synthetica libraries (including
Synthetica's core library 'synthetica.jar').
Enable the Synthetica Look and Feel at startup time in your application:
import de.javasoft.plaf.synthetica.SyntheticaClassyLookAndFeel;
try {
UIManager.setLookAndFeel(new SyntheticaClassyLookAndFeel());
} catch (Exception e) {
e.printStackTrace();

This is the code to add JPanel as a Tab.
jTabbedPane2.addTab("Swimmer",new SwimmerPanel());
What is the error?
You probably didn't initialized the JTabbedPane :
JTabbedPane jTabbedPane2 = new JTabbedPane();

The version of Report designer and bi server should be same. try that and post the result.
The error says the file already exists. You must either delete the file beforehand or check the "overwrite" checkbox.
Since going to 1.7.0_45 (and 51) my program sometimes hangs. All of it's windows work OK except for one, it's fairly complex and has around 60 JButtons, JTextFields, two JScrollbars, JLabels etc. But so do all my other windows and they work fine.
I've put debug lines to the console so I can see where the program is hanging and it seems to be during the repaint() fn. It's hanging at the line
Graphics g = getGraphics();
It has managed to draw some stuff to the screen so it's not the first call to repaint that's the issue. Looks like this: http://www.unixnerd.demon.co.uk/hungjava.jpg
I get this StackTrace. None of the lines of code are in my program. It only happens maybe one time in ten if I open and close the window. Never had the issue with Java 1.6.x. Happens on a few PCs (all Windows 7), not just mine.
Grateful for any ideas.

Im working on my old project at the moment using jide libraries, I used netbeans as my IDE, it works fine when I was working with it in Windows 7 a year ago.
Currently I'm using OS X Mavericks and using netbeans 7.2.1, when I try to drag the component from the palette manager i got this error.
Got anyone also encounter this?

Added the error log:

You get this error because your code is compiled against JDK1.6 but your runtime is not. In my case it was JRE1.7
You can fix this by making sure you JRE and JDK are the same versions.
For me, I changed my eclipse run config from 1.7 (default) to 1.6
