Migrating JDBC Data Access Objects to use EJB3
Persistence is one of the greatest challenges for building applications. There are many options for building persistence layers. Data Access Objects (DAO) is a popular design pattern for building the persistence layer of a J2EE application. Developers use this design pattern primarily to separate their JDBC code from business logic. The EJB3 Java Persistence API, which defines the persistence API for the Java platform based on O-R solutions such as Oracle TopLink and JBoss Hibernate, lets developers skip the mundane task of building DAO and JDBC code. Most developers will be using the EJB3 Java Persistence API instead of writing JDBC code with DAO.
In this article, Debu Panda discusses what you need to do to migrate your DAO-based application to the EJB3 Java Persistence API.
