| Provides the means for dynamically plugging in support for accessing | |
| naming and directory services through the <tt>javax.naming</tt> | |
| and related packages. | |
| <p> | |
| This package defines the service provider interface (SPI) of the Java Naming | |
| and Directory Interface<font size=-2><sup>TM</sup></font> (JNDI). | |
| JNDI provides naming and directory functionality to applications | |
| written in the Java programming language. It is designed to be | |
| independent of any specific naming or directory service | |
| implementation. Thus a variety of services--new, emerging, and | |
| already deployed ones--can be accessed in a common way. | |
| <p> | |
| The JNDI SPI provides the means for creating JNDI service providers, | |
| through which JNDI applications access different naming and | |
| directory services. | |
| <h4>Plug-in Architecture</h4> | |
| The service provider package allows different implementations to be plugged in | |
| dynamically. | |
| These different implementations include those for the | |
| <em>initial context</em>, | |
| and implementations for contexts that can be reached | |
| from the initial context. | |
| <h4>Java Object Support</h4> | |
| The service provider package provides support | |
| for implementors of the | |
| <tt>javax.naming.Context.lookup()</tt> | |
| method and related methods to return Java objects that are natural | |
| and intuitive for the Java programmer. | |
| For example, when looking up a printer name from the directory, | |
| it is natural for you to expect to get | |
| back a printer object on which to operate. | |
| <h4>Multiple Naming Systems (Federation)</h4> | |
| JNDI operations allow applications to supply names that span multiple | |
| naming systems. So in the process of completing | |
| an operation, one service provider might need to interact | |
| with another service provider, for example, to pass on | |
| the operation to be continued in the next naming system. | |
| The service provider package provides support for | |
| different providers to cooperate to complete JNDI operations. | |
| <h2>Package Specification</h2> | |
| The JNDI SPI Specification and related documents can be found in the | |
| <a href="../../../../technotes/guides/jndi/index.html">JNDI documentation</a>. | |
