Just downloaded the demo and installed. When the application runs I get the following error:

Hello,

Did you install <oXygen/> with the install kit which includes a JVM ? If not please try that install kit. If the problem persists there is a Windows display configuration problem on your machine. You should reset to the default display settings of Windows. Another possible fix which worked for other users is to make sure the latest video card driver published by the video card manufacturer is installed in Windows, and to try to switch between 16 bit and 32 bit color depth in the video card configuration settings. Also you should try with a different version of Java (1.4.2 if you are using 1.5.0 now).

Regards,
Sorin

Thank you for the help. In case it is of use to you...

I first uninstalled oXygen and installed the version with the JVM included as you suggested. That produced the same results.

I next uninstalled JRE 1.5.0 and installed JRE 1.4.2 and now I'm up and running.

Thanks again for the help.

FYI

I got everything working fine several weeks ago and then, today I was getting the NullPointer Exception again. I'm guessing that something on my system autoupdated which changed whatever setting allowed the program to work correctly. So I decided to try v7.1 and I got different exception messages but it still would not work. After several hours of trial and error I changed my Appearance setting from custom to Windows XP Style and all my problems went away.

While I'm happy to have this working again I'm frankly a little pissed off that your program is so brittle. Is it really wise for your program to expect a particular appearance setting to work correctly? I want my 3 hours back.

<oXygen/> does not expect some particular display settings to work correctly. In the previous stacktrace that you posted a library used in <oXygen/> could not be initialized on your machine with your display settings. It is hard to say what is wrong but I think most Windows users (Windows 2000, Windows XP, etc) do not experience that. Please post the stacktrace of the error that you get now to see if the problem is in <oXygen/> code. You can see the stacktrace in a console by starting the application with the oxygen.bat script.

It will be also useful to find if the problem can be reproduced and how. We can then report that to the docking framework provider and I am sure they will fix it.

I appologize for my previous comment. Of course I know that is not your intention and I'm sorry for being less helpful. Unfortunately, I did not save the stack trace and I am unable to reproduce the problem.

What I can tell you, and I hope it is at least somewhat helpful, is that I had both version 7.0 and version 7.1 installed and both produced an exception but the stacktrace was different for each. I tried Java 1.4.2 and 1.5 and both reproduced the same stacktrace for each version. The version 7.1 stacktrace I think started in something like GetWinXPStyle (I'm not sure if that is exactly correct). That is what finally prompted to change my appearance to the default for Windows XP.

I've since changed just about every setting in appearance in an attempt to reproduce the error with no luck. I'm fairly certain that I have my settings back to where they were before. With that I would guess that v7.1 may only produce the problem if it has not initialized some setting properly.

Again sorry for the post above but if I didn't love your program so much I wouldn't get upset when it doesn't work. I use it at work and I've had no problems there.
