31 Provides the means for dynamically plugging in support for accessing |
|
32 naming and directory services through the <tt>javax.naming</tt> |
|
33 and related packages. |
|
34 |
|
35 <p> |
|
36 This package defines the service provider interface (SPI) of the Java Naming |
|
37 and Directory Interface<font size=-2><sup>TM</sup></font> (JNDI). |
|
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. |
|
58 |
|
59 <h4>Java Object Support</h4> |
|
60 |
|
61 The service provider package provides support |
|
62 for implementors of the |
|
63 <tt>javax.naming.Context.lookup()</tt> |
|
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 |
|
