Spring and Java EE 5
Part 1: Simplicity and power combined

Simplified Programming Model with Java EE 5
Java EE 5 radically simplifies the development of enterprise applications by:

  • Adopting a plain old Java object (POJO) programming standard and setting intelligent defaults for EJB components
  • Eliminating the need for deployment descriptors and using Java metadata annotations for deployment settings instead
  • Introducing a simplified POJO persistence model similar to Oracle TopLink and JBoss Hibernate
  • Using dependency injection instead of the Java Naming and Directory Interface (JNDI) to locate resources and EJB components
