This is the superclass of all exceptions thrown by
operations in the Context and DirContext interfaces.
The nature of the failure is described by the name of the subclass.
This exception captures the information pinpointing where the operation
failed, such as where resolution last proceeded to.

    

  •  Resolved Name. Portion of name that has been resolved.

  •  Resolved Object. Object to which resolution of name proceeded.

  •  Remaining Name. Portion of name that has not been resolved.

  •  Explanation. Detail explaining why name resolution failed.

  •  Root Exception. The exception that caused this naming exception
                    to be thrown.


null is an acceptable value for any of these fields. When null,
it means that no such information has been recorded for that field.


A NamingException instance is not synchronized against concurrent
multithreaded access. Multiple threads trying to access and modify
a single NamingException instance should lock the object.


This exception has been retrofitted to conform to
the general purpose exception-chaining mechanism.  The
root exception (or root cause) is the same object as the
cause returned by the Throwable.getCause() method.
