Naming System

Purpose

The J2EE Engine naming system is developed in accordance with the JNDI™ 1.2 Specification to meet the Java™ 2 Enterprise Edition (J2EE™) requirements. The system provides functions based on the JNDI™ 1.2 Specification, as well as some additional features related to its work in a cluster.

The J2EE Engine naming system is represented by the JNDI Registry service that provides a way by which names are associated with objects, and objects are found based on their names. The service performs binding, rebinding, and unbinding operations.

Features

The JNDI Registry service specific features are:

Information collection - stores the data using a nonpersistent storage (the data is stored in the memory). Therefore, rebooting the J2EE Engine assures that all stored objects will be removed from the naming.
Tree structure - the naming contexts and the objects are arranged in a hierarchy. For more information, see Browsing the Naming Tree .
Link references - the J2EE Engine services' interfaces and J2EE components (for example, enterprise beans) can be obtained from the JNDI Registry service.
The naming tree can be accessed from the whole cluster. That is, the data can be replicated.
Security - the JNDI Registry service uses the Security Provider Service for ensuring maximum security of the naming system. For more information, see Assigning and Removing Access Permissions .
