Appendix C: JNDI Change History
JNDI 1.2: JNDI Changes Since JNDI 1.1
- Added
javax.naming.event
package.
- Added
javax.naming.ldap
package.
- Added support for configuration using resource files. See Chapter 6 of the JNDI API document.
API-related Changes
- Added
NamingEnumeration.close()
for cancelling or terminating enumerations.
- Added
ReferralException.getReferralContext(Hashtable env)
and ReferralException.retryReferral()
to allow creation and retry of referral context with different environment properties.
- Clarified how context methods that accept
Name
argument should deal with CompositeName
and nonCompositeName
arguments. Specifically, instances of CompositeName
are treated as composite name, while al
l others are treated as compound name.
- Added
Context.getNameInNamespace()
for retrieving the full name of a context within its own namespace.
- Clarified definition of the class factory location of a
Reference
object. Specifically, the location is a codebase, which consists of a list space-separated URLs.
- Added support for ordered multivalued attributes to
Attribute
and BasicAttribute
.
- Added
BasicAttributes.equals()
and BasicAttributes.hashCode()
.
- Redefined semantics of
DirContext.getSchemaClassDefinition()
so that it returns a context that contains the DirContext
objects of class definitions, rather than returning one (arbitrary) class definition.
- Added protected
InitialContext
/InitialDirContext
constructors to allow lazy initialization. Useful for subclass implementations.
SPI-related Changes
- Added
StateFactory
/NamingManager.getStateToBind()
, analogous to ObjectFactory
/NamingManager.getObjectInstance()
, for transforming an object's state before the object is bound in the naming/directory
service.
- Added interfaces
DirObjectFactory
and DirStateFactory
to better support service providers that implement the DirContext
interface. Added
DirectoryManager.getObjectInstance()
and
DirectoryManager.getStateToStore()
to use these interfaces.
- Refined definition of
NamingManager.getObjectInstance()
to not treat URL strings specially. Instead, the URL should be wrapped inside a Reference
whose RefAddr
type is "URL".
- Made
ResolveResult
implement Serializable
.
- Defined a special form of
Reference
called a next naming system (nns) reference for supporting "dynamic federation". This reference has a RefAddr
type of "nns" and a content consisting of the resolved object.
- Added the string constant
NamingManager.CPE
which names a property set by NamingManager.getContinuationContext()
/DirectoryManager.getContinuationContext()
. The value of this property is an instance of
CannotProceedException
.
This is useful to service providers that implement federation by chaining the CPEs.
- Defined a convention for service providers to use when naming environment properties. See Section 6.1.
