Chapter 22. The javax.naming Package

The javax.naming package contains the core interfaces, classes, and exceptions for performing naming operations with JNDI. Context represents named objects in a naming system, while InitialContext provides an entry point into a naming system. Binding is the association between a name and an object in a naming system. NamingException is the root of a large collection of naming exceptions defined by JNDI. Figure 22-1 shows the classes and interfaces of the javax.naming package, while Figure 22-2 shows the exception hierarchy.

	public AuthenticationException ();
	public AuthenticationException (String explanation);
}

Hierarchy: Object-->Throwable(Serializable)-->Exception-->NamingException-->NamingSecurityException-->AuthenticationException

AuthenticationNotSupportedException

serializable checked

Thrown when the requested type of authentication is not supported.

public class AuthenticationNotSupportedException extends NamingSecurityException {

BinaryRefAddr

JNDI 1.1

javax.naming

CannotProceedException

JNDI 1.1

javax.naming

serializable checked

Thrown when a service provider cannot further resolve a name, such as when a component of a name resides in another service provider.

	public CommunicationException (String explanation);
}

Hierarchy: Object-->Throwable(Serializable)-->Exception-->NamingException-->CommunicationException

CompositeName

JNDI 1.1

javax.naming

cloneable serializable

This class represents a sequence of names that span multiple namespaces. Each component of a CompositeName is a String name. The CompositeName does not know to which naming system each name component belongs. JNDI uses the forward slash character ("/") to separate constituent name components.

public class CompositeName implements Name {
//	Public Constructors
	public CompositeName ();
	public CompositeName (String n) throws InvalidNameException;
//	Protected Constructors
	protected CompositeName (java.util.Enumeration comps);
//	Methods implementing Name

Thrown when JNDI has experienced a configuration problem, such as a missing environment property or a misconfigured security protocol.

public class ConfigurationException extends NamingException {
//	Public Constructors
	public ConfigurationException ();
	public ConfigurationException (String explanation);
}

Hierarchy: Object-->Throwable(Serializable)-->Exception-->NamingException-->ConfigurationException

Context

JNDI 1.1

javax.naming

This interface represents an object in a naming system. A Context keeps track of a set of name-to-object bindings for its subordinates in the naming system, so it defines methods to examine and update these bindings. The lookup() method looks up a subordinate object, while list() and listBindings() provide access to all of the subordinates.

A Context only knows about its subordinates, not about itself or what is above it in the naming system. Thus, there are no methods to get the name of a Context or move up in the naming hierarchy.

public abstract interface Context {
//	Public Constants

}

Hierarchy: Object-->Throwable(Serializable)-->Exception-->NamingException-->ContextNotEmptyException

InitialContext

JNDI 1.1

javax.naming

This class represents the starting point for accessing a naming system. Typically, you set the value of the java.naming.factory.initial property (represented by the constant Context.INITIAL_CONTEXT_FACTORY) to the fully qualified package name of a factory class in a JNDI service provider. This factory class creates an InitialContext that is appropriate for the naming system you are using.

Name

JNDI 1.1

javax.naming

cloneable serializable

This interface represents the name of an object in a naming system. A Name can be either a compound name or a composite name. This interface is used primarily by developers who are writing JNDI service providers, not by JNDI application developers. As an application developer, you can use String objects instead of Name objects to specify names in Context and javax.naming.directory.DirContext method calls.

public abstract interface Name extends Cloneable, Serializable {
//	Public Instance Methods
	public abstract Name add (String comp) throws InvalidNameException;
	public abstract Name add (int posn, String comp) throws InvalidNameException;
	public abstract Name addAll (Name suffix) throws InvalidNameException;
	public abstract Name addAll (int posn, Name n) throws InvalidNameException;
	public abstract Object clone ();

	public NameAlreadyBoundException (String explanation);
}

Hierarchy: Object-->Throwable(Serializable)-->Exception-->NamingException-->NameAlreadyBoundException

NameClassPair

JNDI 1.1

javax.naming

serializable

This class represents the name and class of an object bound to a Context. The list() method of Context returns an NamingEnumeration of NameClassPair objects. Note that NameClassPair does not represent the object itself; that is the job of its subclass Binding.

public class NameClassPair implements Serializable {
//	Public Constructors
	public NameClassPair (String name, String className);
	public NameClassPair (String name, String className, boolean isRelative);
//	Public Instance Methods

	public NameNotFoundException (String explanation);
}

Hierarchy: Object-->Throwable(Serializable)-->Exception-->NamingException-->NameNotFoundException

NameParser

JNDI 1.1

javax.naming

This interface is for parsing names from a hierarchical namespace. A NameParser knows the syntactic information, such as left-to-right orientation and the name separator, needed to parse names.

public abstract interface NameParser {
//	Public Instance Methods
	public abstract Name parse (String name) throws NamingException;
}

Returned By: javax.naming.Context.getNameParser(), InitialContext.getNameParser()

NamingEnumeration

JNDI 1.1

javax.naming

This interface represents a list of items returned from a JNDI operation. It extends java.util.Enumeration, so a NamingEnumeration can be treated as a normal enumeration.

public abstract interface NamingEnumeration extends java.util.Enumeration {
//	Public Instance Methods
	public abstract boolean hasMore () throws NamingException;
	public abstract Object next () throws NamingException;
}

Hierarchy: (NamingEnumeration(java.util.Enumeration))

NamingException

JNDI 1.1

javax.naming

serializable checked

The base class of all exceptions thrown by Context and javax.naming.directory.DirContext methods. NamingException can include information about where the operation failed, such as the portion of a name that has been resolved and the portion that remains to be resolved. A NamingException can also include a root cause exception, which is the exception object that caused the naming exception to be thrown.

public class NamingException extends Exception {
//	Public Constructors

Hierarchy: Object-->Throwable(Serializable)-->Exception-->NamingException-->NotContextException

OperationNotSupportedException

JNDI 1.1

javax.naming

serializable checked

Thrown when the provider's implementation of Context does not support a method that has been invoked (e.g., trying to list the subordinates of a leaf object like a print job that by definition cannot have any children).

public class OperationNotSupportedException extends NamingException {
//	Public Constructors
	public OperationNotSupportedException ();

}

RefAddr

JNDI 1.1

javax.naming

This abstract class represents the address of a communications end point. It is used by Reference to represent the communication mechanism and address of a reference. Concrete implementations support addresses such as URLs, DNS names, and IP addresses.

Reference

JNDI 1.1

javax.naming

cloneable serializable

This class represents an object external to a naming system that is referred to by an object in the naming system. A Reference contains an address for retrieving the object from its naming system. The address is a communications end point that enables JNDI to contact the object. The address can be any concrete subclass of RefAddr, such as a StringRefAddr for representing a URL or DNS name. A Reference also contains the class name of the referenced object.

public class Reference implements Cloneable, Serializable {
