[Springframework-developer] Petclinic demo app prototype - JBoss/HSQL Take 2

[Ken K. <kk...@kk...>]

Thomas,

Thanks again for your help. I have already made the same changes in my=20
own latest working version as you describe in 1. I very much wanted to=20
retain the "dataSource" bean because it does show how easy it is to=20
switch datasources. The value of this will become even more apparent=20
when I have refactored to separate the persistence code from the=20
business logic.
