javax.naming package to provide functionality
+for accessing directory services.
+
++This package defines the directory operations of the Java Naming and +Directory Interface™ (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. + +
DirContext
+interface represents a directory context.
+It defines methods for examining and updating attributes associated with a
+directory object, or directory entry as it is sometimes
+called.
+
+You use getAttributes() to retrieve the attributes
+associated with a directory object (for which you supply the name).
+Attributes are modified using modifyAttributes().
+You can add, replace, or remove attributes and/or attribute values
+using this operation.
+
+DirContext also behaves as a naming context
+by extending the Context interface in the javax.naming package.
+This means that any directory object can also provide
+a naming context.
+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.
+
+
DirContext 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
+search() method.
+There are other overloaded forms of search()
+that support more sophisticated search filters.
