public abstract class LdapReferralException extends ReferralException
This abstract class is used to represent an LDAP referral exception. It extends the base ReferralException
by providing a getReferralContext()
method that accepts request controls. LdapReferralException is an abstract class. Concrete implementations of it determine its synchronization and serialization properties.
A Control[]
array passed as a parameter to the getReferralContext()
method is owned by the caller. The service provider will not modify the array or keep a reference to it, although it may keep references to the individual Control
objects in the array.

- 1.3

Method Detail
getReferralContext
public abstract Context getReferralContext() throws NamingException
Retrieves the context at which to continue the method using the context's environment and no controls. The referral context is created using the environment properties of the context that threw the ReferralException
and no controls.
This method is equivalent to
getReferralContext(ctx.getEnvironment(), null);where
ctx
is the context that threw the ReferralException.
It is overridden in this class for documentation purposes only. See ReferralException
for how to use this method.
- Specified by:
-
getReferralContext
in classReferralException
- Returns:
- The non-null context at which to continue the method.
- Throws:
-
NamingException
- If a naming exception was encountered. Call eitherretryReferral()
orskipReferral()
to continue processing referrals.
getReferralContext
public abstract Context getReferralContext(Hashtable<?,?> env) throws NamingException
Retrieves the context at which to continue the method using environment properties and no controls. The referral context is created using env
as its environment properties and no controls.
This method is equivalent to
getReferralContext(env, null);
It is overridden in this class for documentation purposes only. See ReferralException
for how to use this method.
- Specified by:
-
getReferralContext
in classReferralException
- Parameters:
-
env
- The possibly null environment to use when retrieving the referral context. If null, no environment properties will be used. - Returns:
- The non-null context at which to continue the method.
- Throws:
-
NamingException
- If a naming exception was encountered. Call eitherretryReferral()
orskipReferral()
to continue processing referrals.
getReferralContext
public abstract Context getReferralContext(Hashtable<?,?> env, Control[] reqCtls) throws NamingException
Retrieves the context at which to continue the method using request controls and environment properties. Regardless of whether a referral is encountered directly during a context operation, or indirectly, for example, during a search enumeration, the referral exception should provide a context at which to continue the operation. To continue the operation, the client program should re-invoke the method using the same arguments as the original invocation.
reqCtls
is used when creating the connection to the referred server. These controls will be used as the connection request controls for the context and context instances derived from the context. reqCtls
will also be the context's request controls for subsequent context operations. See the LdapContext
class description for details.
This method should be used instead of the other two overloaded forms when the caller needs to supply request controls for creating the referral context. It might need to do this, for example, when it needs to supply special controls relating to authentication.
Service provider implementors should read the "Service Provider" section in the LdapContext
class description for implementation details.
- Parameters:
-
reqCtls
- The possibly null request controls to use for the new context. If null or the empty array means use no request controls. -
env
- The possibly null environment properties to use when for the new context. If null, the context is initialized with no environment properties. - Returns:
- The non-null context at which to continue the method.
- Throws:
-
NamingException
- If a naming exception was encountered. Call eitherretryReferral()
orskipReferral()
to continue processing referrals.
