Just a quick update on my talk at the Java Web User Group in London last night. Thanks for those who made - as always it was an enjoyable evening.
Here's a copy of the presentation.
A main focus of my presentation was a demo based on an Impala version of the Spring Petclinic application - one of the main reference applications bundled with the Spring Framework.
During the demo I introduced a new feature to the application, involving a new database table, some new Hibernate mappings, persistence code, as well as some enhancements to the web presentation layer. The changes were made without having to restart the application during the demo, all updates were made on the fly.
The source code for the demo is available from the Impala subversion repository. The changes made during the demo are in this file.
