Whether you are using simple objects or collections, Hibernate reduces your development time by handling most of the common data persistence tasks. This code-intensive text will take you through Hibernate's major components and show you exactly how to use it to enhance your current development practices and toolsets.You will learn how to install Hibernate, build the development environment, and configure Hibernate for a variety of databases, including DB2(R), HypersonicSQL, MySQL(R), Oracle(R), and PostgreSQL. Then you'll learn the details of connecting to databases using Hibernate, creating persistent classes and objects, working with SQL and HQL (the Hibernate Query Language), and managing transactions. Finally, you will take that basic knowledge into your real-world applications, learning to use Hibernate with other tools such as Eclipse, Tomcat, Maven, Struts, and Xdoclet.What you will learn from this bookHow Hibernate maps objects to a relational databaseHow to build a development environment for using Hibernate in a standalone context or in coordination with TomcatMethods of creating persistent objectsQuery techniques using both traditional SQL and Hibernate Query LanguageThe DAO design pattern and how to use DAO with HibernateThe application of Hibernate within a Maven project management systemHow to incorporate Aspect J and Hibernate for complete controlHow to use advanced caching techniques to improve Hibernate's performanceHow to use XDoclet with Hibernate to reduce your development timeThe procedure for using Velocity and Struts with HibernateWho this book is forThis book is for professional Java developers who already know how to build sophisticated applications and have at least a general familiarity with databases, Java application development, and Web development.
