This class is the starting context for performing naming operations.

All naming operations are relative to a context. The initial context implements the Context interface and provides the starting point for resolution of names.

When the initial context is constructed, its environment is initialized with properties defined in the environment parameter passed to the constructor, and in any application resource files.

JNDI determines each property's value by merging the values from the following two sources, in order:

  1. The first occurrence of the property from the constructor's environment parameter and system properties.
  2. The application resource files (jndi.properties).
For each property found in both of these two sources, or in more than one application resource file, the property's value is determined as follows. If the property is one of the standard JNDI properties that specify a list of JNDI factories (see Context), all of the values are concatenated into a single colon-separated list. For other properties, only the first value found is used.

The initial context implementation is determined at runtime. The default policy uses the environment property "java.naming.factory.initial", which contains the class name of the initial context factory. An exception to this policy is made when resolving URL strings, as described below.

When a URL string (a String of the form scheme_id:rest_of_name) is passed as a name parameter to any method, a URL context factory for handling that scheme is located and used to resolve the URL. If no such factory is found, the initial context specified by "java.naming.factory.initial" is used. Similarly, when a CompositeName object whose first component is a URL string is passed as a name parameter to any method, a URL context factory is located and used to resolve the first name component. See NamingManager.getURLContext() for a description of how URL context factories are located.

This default policy of locating the initial context and URL context factories may be overridden by calling NamingManager.setInitialContextFactoryBuilder().

NoInitialContextException is thrown when an initial context cannot be instantiated. This exception can be thrown during any interaction with the InitialContext, not only when the InitialContext is constructed. For example, the implementation of the initial context might lazily retrieve the context only when actual methods are invoked on it. The application should not have any dependency on when the existence of an initial context is determined.

When the environment property "java.naming.factory.initial" is non-null, the InitialContext constructor will attempt to create the initial context specified therein. At that time, the initial context factory involved might throw an exception if a problem is encountered. However, it is provider implementation-dependent when it verifies and indicates to the users of the initial context any environment property- or connection- related problems. It can do so lazily--delaying until an operation is performed on the context, or eagerly, at the time the context is constructed.

An InitialContext instance is not synchronized against concurrent access by multiple threads. Multiple threads each manipulating a different InitialContext instance need not synchronize. Threads that need to access a single InitialContext instance concurrently should synchronize amongst themselves and provide the necessary locking.

Constructor Detail

InitialContextback to summary
protected InitialContext(boolean lazy) throws NamingException

Constructs an initial context with the option of not initializing it. This may be used by a constructor in a subclass when the value of the environment parameter is not yet known at the time the InitialContext constructor is called. The subclass's constructor will call this constructor, compute the value of the environment, and then call init() before returning.

Parameters
lazy:boolean

true means do not initialize the initial context; false is equivalent to calling new InitialContext()

Exceptions
NamingException:
if a naming exception is encountered
Since
1.3

init(Hashtable)
InitialContextback to summary
public InitialContext() throws NamingException

Constructs an initial context. No environment properties are supplied. Equivalent to new InitialContext(null).

Exceptions
NamingException:
if a naming exception is encountered
See Also
InitialContext(Hashtable)
InitialContextback to summary
public InitialContext(Hashtable<?, ?> environment) throws NamingException

Constructs an initial context using the supplied environment. Environment properties are discussed in the class description.

This constructor will not modify environment or save a reference to it, but may save a clone. Caller should not modify mutable keys and values in environment after it has been passed to the constructor.

Parameters
environment:Hashtable<?, ?>

environment used to create the initial context. Null indicates an empty environment.

Exceptions

bindback to summary
public void bind(Name name, Object obj) throws NamingException

Implements javax.naming.Context.bind.

Doc from javax.naming.Context.bind.

Binds a name to an object. All intermediate contexts and the target context (that named by all but terminal atomic component of the name) must already exist.

Exceptions
NamingException:
if a naming exception is encountered
NameAlreadyBoundException:
if name is already bound
InvalidAttributesException:
if object did not supply all mandatory attributes
closeback to summary
public void close() throws NamingException

Implements javax.naming.Context.close.

Doc from javax.naming.Context.close.

Closes this context. This method releases this context's resources immediately, instead of waiting for them to be released automatically by the garbage collector.

This method is idempotent: invoking it on a context that has already been closed has no effect. Invoking any other method on a closed context is not allowed, and results in undefined behaviour.

Exceptions
NamingException:
if a naming exception is encountered
composeNameback to summary
public String composeName(String name, String prefix) throws NamingException

Implements javax.naming.Context.composeName.

Composes the name of this context with a name relative to this context. Since an initial context may never be named relative to any context other than itself, the value of the prefix parameter must be an empty name ("").

Exceptions
NamingException:

Doc from javax.naming.Context.composeName.

if a naming exception is encountered

composeNameback to summary
public Name composeName(Name name, Name prefix) throws NamingException

Implements javax.naming.Context.composeName.

Composes the name of this context with a name relative to this context. Since an initial context may never be named relative to any context other than itself, the value of the prefix parameter must be an empty name.

Exceptions
NamingException:

if a naming exception is encountered

createSubcontextback to summary
public Context createSubcontext(String name) throws NamingException

Implements javax.naming.Context.createSubcontext.

Doc from javax.naming.Context.createSubcontext.

Creates and binds a new context. See createSubcontext(Name) for details.

Exceptions
NamingException:
if a naming exception is encountered
NameAlreadyBoundException:
if name is already bound
InvalidAttributesException:
if creation of the subcontext requires specification of mandatory attributes
createSubcontextback to summary
public Context createSubcontext(Name name) throws NamingException

Implements javax.naming.Context.createSubcontext.

Doc from javax.naming.Context.createSubcontext.

Creates and binds a new context. Creates a new context with the given name and binds it in the target context (that named by all but terminal atomic component of the name). All intermediate contexts and the target context must already exist.

Exceptions
NamingException:
if a naming exception is encountered
NameAlreadyBoundException:
if name is already bound
InvalidAttributesException:
if creation of the subcontext requires specification of mandatory attributes
destroySubcontextback to summary
public void destroySubcontext(String name) throws NamingException

Implements javax.naming.Context.destroySubcontext.

Doc from javax.naming.Context.destroySubcontext.

Destroys the named context and removes it from the namespace. See destroySubcontext(Name) for details.

Exceptions
NamingException:
if a naming exception is encountered
NameNotFoundException:
if an intermediate context does not exist
NotContextException:
if the name is bound but does not name a context, or does not name a context of the appropriate type
ContextNotEmptyException:
if the named context is not empty
destroySubcontextback to summary
public void destroySubcontext(Name name) throws NamingException

Implements javax.naming.Context.destroySubcontext.

Doc from javax.naming.Context.destroySubcontext.

Destroys the named context and removes it from the namespace. Any attributes associated with the name are also removed. Intermediate contexts are not destroyed.

This method is idempotent. It succeeds even if the terminal atomic name is not bound in the target context, but throws NameNotFoundException if any of the intermediate contexts do not exist.

In a federated naming system, a context from one naming system may be bound to a name in another. One can subsequently look up and perform operations on the foreign context using a composite name. However, an attempt destroy the context using this composite name will fail with NotContextException, because the foreign context is not a "subcontext" of the context in which it is bound. Instead, use unbind() to remove the binding of the foreign context. Destroying the foreign context requires that the destroySubcontext() be performed on a context from the foreign context's "native" naming system.

Exceptions
NamingException:
if a naming exception is encountered
NameNotFoundException:
if an intermediate context does not exist
NotContextException:
if the name is bound but does not name a context, or does not name a context of the appropriate type
ContextNotEmptyException:
if the named context is not empty
doLookupback to summary
public static <T> T doLookup(Name name) throws NamingException

A static method to retrieve the named object. This is a shortcut method equivalent to invoking:

InitialContext ic = new InitialContext(); Object obj = ic.lookup();

If name is empty, returns a new instance of this context (which represents the same naming context as this context, but its environment may be modified independently and it may be accessed concurrently).

Parameters
<T>
the type of the returned object
name:Name

the name of the object to look up

Returns:T

the object bound to name

A static method to retrieve the named object. See doLookup(Name) for details.

Parameters
<T>
the type of the returned object
name:String

the name of the object to look up

Returns:T

the object bound to name

getDefaultInitCtxback to summary
protected Context getDefaultInitCtx() throws NamingException

Retrieves the initial context by calling NamingManager.getInitialContext() and cache it in defaultInitCtx. Set gotDefault so that we know we've tried this before.

Returns:Context

The non-null cached initial context.

Exceptions
NamingException:
If a naming exception was encountered.
NoInitialContextException:
If cannot find an initial context.
getEnvironmentback to summary
public Hashtable<?, ?> getEnvironment() throws NamingException

Implements javax.naming.Context.getEnvironment.

Doc from javax.naming.Context.getEnvironment.

Retrieves the environment in effect for this context. See class description for more details on environment properties.

The caller should not make any changes to the object returned: their effect on the context is undefined. The environment of this context may be changed using addToEnvironment() and removeFromEnvironment().

Exceptions
NamingException:
if a naming exception is encountered
getNameInNamespaceback to summary
public String getNameInNamespace() throws NamingException

Implements javax.naming.Context.getNameInNamespace.

Doc from javax.naming.Context.getNameInNamespace.

Retrieves the full name of this context within its own namespace.

Many naming services have a notion of a "full name" for objects in their respective namespaces. For example, an LDAP entry has a distinguished name, and a DNS record has a fully qualified name. This method allows the client application to retrieve this name. The string returned by this method is not a JNDI composite name and should not be passed directly to context methods. In naming systems for which the notion of full name does not make sense, OperationNotSupportedException is thrown.

Exceptions
NamingException:
if a naming exception is encountered
OperationNotSupportedException:
if the naming system does not have the notion of a full name
getNameParserback to summary
public NameParser getNameParser(String name) throws NamingException

Implements javax.naming.Context.getNameParser.

Doc from javax.naming.Context.getNameParser.

Retrieves the parser associated with the named context. See getNameParser(Name) for details.

Exceptions
NamingException:

getNameParserback to summary
public NameParser getNameParser(Name name) throws NamingException

Implements javax.naming.Context.getNameParser.

Doc from javax.naming.Context.getNameParser.

Retrieves the parser associated with the named context. In a federation of namespaces, different naming systems will parse names differently. This method allows an application to get a parser for parsing names into their atomic components using the naming convention of a particular naming system. Within any single naming system, NameParser objects returned by this method must be equal (using the equals() test).

Exceptions
NamingException:
if a naming exception is encountered
getURLOrDefaultInitCtxback to summary
protected Context getURLOrDefaultInitCtx(String name) throws NamingException

Retrieves a context for resolving the string name name. If name name is a URL string, then attempt to find a URL context for it. If none is found, or if name is not a URL string, then return getDefaultInitCtx().

See getURLOrDefaultInitCtx(Name) for description of how a subclass should use this method.

Parameters
name:String

The non-null name for which to get the context.

Returns:Context

A URL context for name or the cached initial context. The result cannot be null.

Exceptions
NamingException:
In a naming exception is encountered.
NoInitialContextException:
If cannot find an initial context.
See Also
javax.naming.spi.NamingManager#getURLContext
getURLOrDefaultInitCtxback to summary
protected Context getURLOrDefaultInitCtx(Name name) throws NamingException

Retrieves a context for resolving name. If the first component of name name is a URL string, then attempt to find a URL context for it. If none is found, or if the first component of name is not a URL string, then return getDefaultInitCtx().

When creating a subclass of InitialContext, use this method as follows. Define a new method that uses this method to get an initial context of the desired subclass. 

 protected XXXContext getURLOrDefaultInitXXXCtx(Name name)
 throws NamingException {
  Context answer = getURLOrDefaultInitCtx(name);
  if (!(answer instanceof XXXContext)) {
    if (answer == null) {
      throw new NoInitialContextException();
    } else {
      throw new NotContextException("Not an XXXContext");
    }
  }
  return (XXXContext)answer;
 }
When providing implementations for the new methods in the subclass, use this newly defined method to get the initial context. 
 public Object XXXMethod1(Name name, ...) {
  throws NamingException {
    return getURLOrDefaultInitXXXCtx(name).XXXMethod1(name, ...);
 }
Parameters
name:Name

The non-null name for which to get the context.

Returns:Context

A URL context for name or the cached initial context. The result cannot be null.

Exceptions
NamingException:
In a naming exception is encountered.
NoInitialContextException:
If cannot find an initial context.
