JNDI implementation

WebSphere Application Server - Express includes a name server to provide shared access to Java components, and an implementation of the javax.naming Link outside Information Center JNDI package, which allows users to access the WebSphere Application Server - Express name server through the JNDI naming interface.

In order to provide access to LDAP servers, Option 5 of the IBM Developer Kit for Java provides Sun Microsystems Java 2 Software Development Kit (J2SDK), Standard Edition, version 1.3, and contains the following packages:

WebSphere Application Server - Express does not provide implementations for the javax.naming.directory Link outside Information Center package and the javax.naming.ldapLink outside Information Center package. WebSphere Application Server - Express does not support interfaces defined in the javax.naming.event Link outside Information Center package.

WebSphere Application Server - Express's JNDI implementation is based on version 1.2 of the JNDI interface and was tested with version 1.2.1 of the Sun Microsystems JNDI Service Provider Interface (SPI). The default behavior of this implementation should be adequate for most users. However, users with specific requirements can control certain aspects of the JNDI behavior.
