tt>
javax.naming</
tt> package to provide functionality
for accessing directory services.
This package defines the directory operations 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.
This package allows applications to retrieve and update attributes
associated with objects stored in a directory, and to search for
objects using specified attributes.
<
h4>The Directory Context</
h4>
interface represents a <
em>directory context</
em>.
It defines methods for examining and updating attributes associated with a
<
em>directory object</
em>, or <
em>directory entry</
em> as it is sometimes
You use <
tt>getAttributes()</
tt> to retrieve the attributes
associated with a directory object (for which you supply the name).
Attributes are modified using <
tt>modifyAttributes()</
tt>.
You can add, replace, or remove attributes
and/
or attribute values
<
tt>DirContext</
tt> also behaves as a naming context
by extending the <
tt>Context</
tt> interface in the <
tt>
javax.naming</
tt> package.
This means that any directory object can also provide
For example, the directory object for a person might contain
the attributes of that person, and at the same time provide
a context for naming objects relative to that person
such as his printers and home directory.
<
tt>DirContext</
tt> contains methods for
performing content-based searching of the directory.
In the simplest and most common form of usage, the application
specifies a set of attributes--possibly with specific
values--to match, and submits this attribute set, to the
<
tt>search()</
tt> method.
There are other overloaded forms of <
tt>search()</
tt>
that support more sophisticated <
em>search filters</
em>.
