Ozone port of Petstore in OzoneApps

Friends,

I just checked in an initial port of Petstore to the new OzoneApps area. It is 
based on the EJB version of xPetstore created by Herve Tchepannou. I kept the 
front end web application alost completely unchanged but changed the back-end 
EJB/DAO-RDMBS structure into a tier of Ozone based persistent business 
objects. 

Since Petstore is very data centric in its approach I needed a query system 
and ended up using JXpath for this. 

I have not thought about optimization and performance so I'm sure there are 
many things in that area that could be improved (there is so little data in 
the system - <100 items - so it performes quite well as it is on my machine). 
Please let me know if you have any suggestions for improvement (or just any 
questions about this at all for that matters).

Best regards,
Per
