Abstract: This paper analyzes the difficulties of design in data persistence layer under the J2EE development enviroment. Under the research of three main solutions of data persistence, it introduces Hibernate, the most popular open-souce project in the O-R mapping field. In the end, it discusses the technical profit of J2EE server-side development structure including Hibernate.
