  31 Provides the means for dynamically plugging in support for accessing
  32 naming and directory services through the <code>javax.naming</code>
  33 and related packages.
  34 
  35 <p>
  36 This package defines the service provider interface (SPI) of the Java Naming
  37 and Directory Interface&trade; (JNDI). &nbsp;
  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.

  50 <h2>Plug-in Architecture</h2>
  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 <h2>Java Object Support</h2>
  60 
  61 The service provider package provides support
  62 for implementors of the
  63 <code>javax.naming.Context.lookup()</code>
  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 <h2>Multiple Naming Systems (Federation)</h2>
  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 {@extLink jndi_overview JNDI documentation}.
