I had written a visual solution to the famous eight queens problem seen in Universities. Many people emailed me asking for the source after having seen it. So I finally packaged it, GPLed it, and uploaded it to my website for download. I also uploaded a simple utility that will generate your get/set methods by having your declarations as input. Nothing amazing, but it certainly saves me a load of time. If you want to check these out and even get the source, visit my website.
One piece of feedback I've gotten for the JPropertyBuilder is to have the generated code comply with the Code Conventions for Java (http://java.sun.com/docs/codeconv/h...onvTOC.doc.html). I've been coding in .NET for the past year, so I've gotten used to the way that code is structured. The beauty of open source is that somebody could take my code, add this functionality, and send it back to me to be redistributed.
