Geertjan has already blogged about the new Web 2.0 version of the Java Pet Store Reference Application (version 2.0), and Sean has more info.
Here’s a short video (less than 2 minutes!) of the download, install, config, run process using NetBeans 5.5 beta:
Smaller, lighter, uglier version here.
Bistro! 2.0 
Dear Alexis
I do everything like your vedio and do all instructions( https://blueprints.dev.java.net/petstore/usingnetbeans.html) but I can not start database.
It has an error: “The java DB location is not set correctly.”
How can I do? Could you please suggest me.
Best Regards,
Mai=\^_\^=
Try: Tools > Options > Advanced Options > IDE Configuration > Server And External… > Java DB
The Java DB location (binaries) should be : $GLASSFISH_INSTALL/javadb
and the Database location (the data) should be :
$HOME/.netbeans-derby
Change accordingly.
