public class NamingException

extends Exception

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.

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.

Since:

1.3

getRootCause(), setRootCause(java.lang.Throwable)

NamingException

public NamingException(String explanation)

Constructs a new NamingException with an explanation. All unspecified fields are set to null.

Parameters:

explanation - A possibly null string containing additional detail about this exception.

See Also:

Throwable.getMessage()

NamingException

public NamingException()

Constructs a new NamingException. All fields are set to null.

getResolvedName

public Name getResolvedName()

Retrieves the leading portion of the name that was resolved successfully.

Returns:

The part of the name that was resolved successfully. It is a composite name. It can be null, which means the resolved name field has not been set.

See Also:

getResolvedObj(), setResolvedName(javax.naming.Name)

getRemainingName

public Name getRemainingName()

Retrieves the remaining unresolved portion of the name.

Returns:

The part of the name that has not been resolved. It is a composite name. It can be null, which means the remaining name field has not been set.

See Also:

setRemainingName(javax.naming.Name), appendRemainingName(javax.naming.Name), appendRemainingComponent(java.lang.String)

getResolvedObj

public Object getResolvedObj()

Retrieves the object to which resolution was successful. This is the object to which the resolved name is bound.

Returns:

The possibly null object that was resolved so far. null means that the resolved object field has not been set.

See Also:

getResolvedName(), setResolvedObj(java.lang.Object)

getExplanation

public String getExplanation()

Retrieves the explanation associated with this exception.

Returns:

The possibly null detail string explaining more about this exception. If null, it means there is no detail message for this exception.

See Also:

Throwable.getMessage()

setResolvedName

public void setResolvedName(Name name)

Sets the resolved name field of this exception.

name is a composite name. If the intent is to set this field using a compound name or string, you must "stringify" the compound name, and create a composite name with a single component using the string. You can then invoke this method using the resulting composite name.

A copy of name is made and stored. Subsequent changes to name does not affect the copy in this NamingException and vice versa.

Parameters:

name - The possibly null name to set resolved name to. If null, it sets the resolved name field to null.

See Also:

getResolvedName()

setRemainingName

public void setRemainingName(Name name)

Sets the remaining name field of this exception.

name is a composite name. If the intent is to set this field using a compound name or string, you must "stringify" the compound name, and create a composite name with a single component using the string. You can then invoke this method using the resulting composite name.

A copy of name is made and stored. Subsequent changes to name does not affect the copy in this NamingException and vice versa.

Parameters:

name - The possibly null name to set remaining name to. If null, it sets the remaining name field to null.

See Also:

getRemainingName(), appendRemainingName(javax.naming.Name), appendRemainingComponent(java.lang.String)

setResolvedObj

public void setResolvedObj(Object obj)

Sets the resolved object field of this exception.

Parameters:

obj - The possibly null object to set resolved object to. If null, the resolved object field is set to null.

See Also:

getResolvedObj()

appendRemainingComponent

public void appendRemainingComponent(String name)

Add name as the last component in remaining name.

Parameters:

name - The component to add. If name is null, this method does not do anything.

See Also:

setRemainingName(javax.naming.Name), getRemainingName(), appendRemainingName(javax.naming.Name)

appendRemainingName

public void appendRemainingName(Name name)

Add components from 'name' as the last components in remaining name.

name is a composite name. If the intent is to append a compound name, you should "stringify" the compound name then invoke the overloaded form that accepts a String parameter.

Subsequent changes to name does not affect the remaining name field in this NamingException and vice versa.

Parameters:

name - The possibly null name containing ordered components to add. If name is null, this method does not do anything.

See Also:

setRemainingName(javax.naming.Name), getRemainingName(), appendRemainingComponent(java.lang.String)

getRootCause

public Throwable getRootCause()

Retrieves the root cause of this NamingException, if any. The root cause of a naming exception is used when the service provider wants to indicate to the caller a non-naming related exception but at the same time wants to use the NamingException structure to indicate how far the naming operation proceeded.

Returns:

The possibly null exception that caused this naming exception. If null, it means no root cause has been set for this naming exception.

See Also:

setRootCause(java.lang.Throwable), rootException, getCause()

setRootCause

public void setRootCause(Throwable e)

Records the root cause of this NamingException. If e is this, this method does not do anything.

Parameters:

e - The possibly null exception that caused the naming operation to fail. If null, it means this naming exception has no root cause.

See Also:

getRootCause(), rootException, initCause(java.lang.Throwable)

getCause

public Throwable getCause()

Description copied from class: Throwable

Returns the cause of this throwable or null if the cause is nonexistent or unknown. (The cause is the throwable that caused this throwable to get thrown.)

This implementation returns the cause that was supplied via one of the constructors requiring a Throwable, or that was set after creation with the Throwable.initCause(Throwable) method. While it is typically unnecessary to override this method, a subclass can override it to return a cause set by some other means. This is appropriate for a "legacy chained throwable" that predates the addition of chained exceptions to Throwable. Note that it is not necessary to override any of the PrintStackTrace methods, all of which invoke the getCause method to determine the cause of a throwable.

Overrides:

getCause in class Throwable

Returns:

the cause of this throwable or null if the cause is nonexistent or unknown.

initCause

public Throwable initCause(Throwable cause)

Description copied from class: Throwable

Initializes the cause of this throwable to the specified value. (The cause is the throwable that caused this throwable to get thrown.)

This method can be called at most once. It is generally called from within the constructor, or immediately after creating the throwable. If this throwable was created with Throwable.Throwable(Throwable) or Throwable.Throwable(String,Throwable), this method cannot be called even once.

Overrides:

initCause in class Throwable

Parameters:

cause - the cause (which is saved for later retrieval by the Throwable.getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

Returns:

a reference to this Throwable instance.

toString

public String toString()

Generates the string representation of this exception. The string representation consists of this exception's class name, its detailed message, and if it has a root cause, the string representation of the root cause exception, followed by the remaining name (if it is not null). This string is used for debugging and not meant to be interpreted programmatically.

Overrides:

toString in class Throwable

Returns:

The non-null string containing the string representation of this exception.

toString

public String toString(boolean detail)

Generates the string representation in more detail. This string representation consists of the information returned by the toString() that takes no parameters, plus the string representation of the resolved object (if it is not null). This string is used for debugging and not meant to be interpreted programmatically.

Parameters:

detail - If true, include details about the resolved object in addition to the other information.

Returns:

The non-null string containing the string representation.
