Wicket Phonebook is an example of Spring & Hibernate usage in a Wicket web-app.

• The database is an in-memory HSQLDB DB - In this example, the schema gets generated automatically everytime the app starts up.
• Hooking up to a different database is a simple matter of editing src/conf/application.properties.
• All database-related code is inside a DAO object, so Wicket never touches anything database related.
• All Hibernate session management and transaction management is handled by Spring
