Where can I download the source of "appframework.jar" that comes with NetBeans?

Question

I have just started to try NetBeans. I created a new Java Desktop Application project, and it automatically added the JDesktop "appframework-1.0.3.jar" library. However, whenever I try to view its source, the command fails. I tried searching for it online, but I couldn't find it. So where can I download the source code for the "Swing Application Framework" (appframework.jar and swing-worker.jar)?

Answer 1

http://java.net/projects/appframework/sources/svn/show/trunk/AppFramework

the link and the source is too old and hard to be found,luckly i used 30 min find it in : https://java.net/projects/appframework/sources/svn/show/trunk/www/downloads?rev=151

you can see the "source","jar","doc" of appframework-1.0.3.jar at the ending.
