Thought I've bookmarked this a long time ago... "With the adoption of Java™ 5 generics, the idea of a generic typesafe Data Access Object (DAO) implementation has become feasible. In this article, system architect Per Mellqvist presents a generic DAO implementation class based on Hibernate. He then shows you how to use Spring AOP introductions to add a typesafe interface to the class for query execution."
This book is an introduction to Java™ language--a widely used programming language and a platform. It is meant to be both an introductory guide and a useful reference on Java and related technologies.
