We just put up version 3.0 of Microsoft's answer to Suns Pet Shop "Blueprint" application. You can find a running version of the sample application here: http://sampleapps.dotnetjunkies.com/MSPetShop/ - On the default page you'll find links to where you can download the application itself with FULL source code. Also, you'll find benchmarks and performance tests of each version (.NET and J2EE).
Do you think it would be a good idea to start discussion forums for these types of applicaitons???
Let me know!
Enjoy!
