Managing JNDI

The following sections describe how to manage JNDI:

- Overview of JNDI Management

- Viewing the JNDI Tree

- Loading Objects in the JNDI Tree

Overview of JNDI Management

You use the Administration Console to manage JNDI. The JNDI API enables applications to look up objects—such as Data Sources, EJBs, JMS, and MailSessions—by name. The JNDI tree is represented by the left pane in the Administration Console.

For additional information, see Programming WebLogic JNDI.

What Do JNDI and Naming Services Do?

JNDI provides a common-denominator interface to many existing naming services, such as LDAP (Lightweight Directory Access Protocol) and DNS (Domain Name System). These naming services maintain a set of bindings, which relate names to objects and provide the ability to look up objects by name. JNDI allows the components in distributed applications to locate each other.

Viewing the JNDI Tree

To view the objects in the WebLogic Server JNDI tree for a specific server, do the following:

1. Right-click the server node in the left pane. This displays a pop-up menu.

2. Select JNDI Tree. The JNDI tree for this server displays in the right pane.

Loading Objects in the JNDI Tree

Using the Administration Console, you load WebLogic Server J2EE services and components, such as RMI, JMS, EJBs, and JDBC Data Sources, in the JNDI tree.

To load an object in the JNDI tree, choose a name under which you want the object to appear in the JNDI tree. Then enter that name in the JNDI Name attribute field when you create the object. When the object is loaded, JNDI provides a path to the object.

To verify if an object has been loaded, see Viewing the JNDI Tree.

For more information on configuring objects, see Table 11-1 Objects in JNDI Tree.
