  1. Transaction Management, security management, and naming management functionality
  2. APIs of JNDI, JDBC, JTA, JPA, RMI-IIOP, JavaMail, and JMS

The J2EE service is used as one of the component functionality of the J2EE container, and provides functions and APIs to J2EE components such as servlets, JSPs, and Enterprise Beans. The APIs of the J2EE service are used either directly by J2EE components or through the J2EE container.
