EJB Container 

Purpose

This component is an essential part of the J2EE architecture. It manages all enterprise bean instances deployed on the server, and provides all services that are required by an EJB application, such as transaction and security management, clustering, persistence, network distribution of remote clients, scalable management of resources, and so on.

The J2EE Engine EJB architecture is developed according to the Sun Microsystems Enterprise JavaBeans™ Specification. The EJB Container is compatible with Enterprise JavaBeans™ Specification 2.0 and compliant with Enterprise JavaBeans™ Specification 1.1.

Integration

The J2EE Engine EJB Container works together with the Web Container and the Application Client Container to ensure a stable environment and to provide runtime support for the J2EE applications running on the J2EE Engine.

Features

You can administer and monitor at runtime the deployed enterprise beans using the following functions provided by the J2EE Engine EJB Container Service:

·        View and/or store in files information about all enterprise beans, their JAR files and applications

·        Change at runtime the properties of the deployed enterprise beans

·        Generate persistent.xml for the container-managed entity beans to be deployed

·        Enable IIOP Support for EJB Applications

·        Start or stop the message-driven beans running on a server process
