It seems you'll need the sort of specialist help that may not be found here. Most of us are happy just to keep our computers running one way or another

But still, your post made me look up what netbeans actually are. I'm still reading a bit about the subject.
Since you are involved with this already, you might have found this site:
http://www.netbeans.org/community/index.htmlIf not, this seems a good place to look up netbeans problems. I notice the 3rd link down offers a netbeans/java bundle. Perhaps that might be the answer.
