naming and directory services through the <code>javax.naming</code> |
| 2 | 33 |
and related packages. |
34 |
||
35 |
<p> |
|
36 |
This package defines the service provider interface (SPI) of the Java Naming |
|
| 30678 | 37 |
and Directory Interface™ (JNDI). |
| 2 | 38 |
JNDI provides naming and directory functionality to applications |
39 |
written in the Java programming language. It is designed to be |
|
40 |
independent of any specific naming or directory service |
|
41 |
implementation. Thus a variety of services--new, emerging, and |
|
42 |
already deployed ones--can be accessed in a common way. |
|
43 |
||
44 |
<p> |
|
45 |
The JNDI SPI provides the means for creating JNDI service providers, |
|
46 |
through which JNDI applications access different naming and |
|
47 |
directory services. |
|
48 |
||
49 |
||
50 |
<h4>Plug-in Architecture</h4> |
|
51 |
||
52 |
The service provider package allows different implementations to be plugged in |
|
53 |
dynamically. |
|
54 |
These different implementations include those for the |
|
55 |
<em>initial context</em>, |
|
56 |
and implementations for contexts that can be reached |
|
57 |
from the initial context. |

<code>javax.naming.Context.lookup()</code> |
| 2 | 64 |
method and related methods to return Java objects that are natural |
65 |
and intuitive for the Java programmer. |
|
66 |
For example, when looking up a printer name from the directory, |
|
67 |
it is natural for you to expect to get |
|
68 |
back a printer object on which to operate. |
|
69 |
||
70 |
||
71 |
<h4>Multiple Naming Systems (Federation)</h4> |
|
72 |
||
73 |
JNDI operations allow applications to supply names that span multiple |
|
74 |
naming systems. So in the process of completing |
|
75 |
an operation, one service provider might need to interact |
|
76 |
with another service provider, for example, to pass on |
|
77 |
the operation to be continued in the next naming system. |
|
78 |
The service provider package provides support for |
|
79 |
different providers to cooperate to complete JNDI operations. |
|
80 |
||
81 |
||
82 |
<h2>Package Specification</h2> |
|
83 |
||
84 |
The JNDI SPI Specification and related documents can be found in the |
|
85 |
<a href="../../../../technotes/guides/jndi/index.html">JNDI documentation</a>. |
