| 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>. |
