Spec implemented in Application Server 4, Hibernate 3, and Eclipse 1.5 IDE JBoss is upgrading three of its Java middleware products to include an early version of the EJB 3.0 specification.EJBs are pieces of reusable server code that include the business logic of an application. EJB 3.0 aims to make developers more productive, in part by simplifying the API for writing EJB components.“All the EJB services that were there before are still there, but we’ve increased what developers can achieve with them and simplified how they get there,” said Sacha Labourey, JBoss general manager for Europe, the Middle East, and Africa. JBoss is releasing its implementation of EJB 3.0 in updates to Application Server 4, the Hibernate 3 persistence engine, and Eclipse 1.5 IDE.With the app server, developers can use EJB 3.0 and JavaServer Faces technology for building Web applications and business logic. Data persistence is provided through the EJB 3.0 Java Persistence API. A “TraiBlazer” learning app aims to assist developers.Hibernate 3 supports the EJB 3.0 Annotations, Entity Manager, and Java Persistence API. The IDE offers an EJB 3.0 project wizard, a port of the Hibernate console to Eclipse, and an XML mapping file editor. A wizard is included for reverse-engineering database schemas.
