public class CannotProceedException extends NamingException
This exception is thrown to indicate that the operation reached a point in the name where the operation cannot proceed any further. When performing an operation on a composite name, a naming service provider may reach a part of the name that does not belong to its namespace. At that point, it can construct a CannotProceedException and then invoke methods provided by javax.naming.spi.NamingManager (such as getContinuationContext()) to locate another provider to continue the operation. If this is not possible, this exception is raised to the caller of the context operation.
If the program wants to handle this exception in particular, it should catch CannotProceedException explicitly before attempting to catch NamingException.
A CannotProceedException instance is not synchronized against concurrent multithreaded access. Multiple threads trying to access and modify CannotProceedException should lock the object.

Field Detail
remainingNewName
protected Name remainingNewName
Contains the remaining unresolved part of the second "name" argument to Context.rename(). This information is necessary for continuing the Context.rename() operation.
This field is initialized to null. It should not be manipulated directly: it should be accessed and updated using getRemainingName() and setRemainingName().
environment
protected Hashtable<?,?> environment
Contains the environment relevant for the Context or DirContext method that cannot proceed.
This field is initialized to null. It should not be manipulated directly: it should be accessed and updated using getEnvironment() and setEnvironment().
altName
protected Name altName
Contains the name of the resolved object, relative to the context altNameCtx
. It is a composite name. If null, then no name is specified. See the javax.naming.spi.ObjectFactory.getObjectInstance
method for details on how this is used.
This field is initialized to null. It should not be manipulated directly: it should be accessed and updated using getAltName() and setAltName().

,altNameCtx
,ObjectFactory.getObjectInstance(java.lang.Object, javax.naming.Name, javax.naming.Context, java.util.Hashtable<?, ?>)
altNameCtx
protected Context altNameCtx
Contains the context relative to which altName
is specified. If null, then the default initial context is implied. See the javax.naming.spi.ObjectFactory.getObjectInstance
method for details on how this is used.
This field is initialized to null. It should not be manipulated directly: it should be accessed and updated using getAltNameCtx() and setAltNameCtx().
Constructor Detail
CannotProceedException
public CannotProceedException(String explanation)
Constructs a new instance of CannotProceedException using an explanation. All unspecified fields default to null.
- Parameters:
-
explanation
- A possibly null string containing additional detail about this exception. If null, this exception has no detail message. - See Also:
Throwable.getMessage()
CannotProceedException
public CannotProceedException()
Constructs a new instance of CannotProceedException. All fields default to null.
Method Detail
getEnvironment
public Hashtable<?,?> getEnvironment()
Retrieves the environment that was in effect when this exception was created.
- Returns:
- Possibly null environment property set. null means no environment was recorded for this exception.
- See Also:
setEnvironment(java.util.Hashtable<?, ?>)
setEnvironment
public void setEnvironment(Hashtable<?,?> environment)
Sets the environment that will be returned when getEnvironment() is called.
- Parameters:
-
environment
- A possibly null environment property set. null means no environment is being recorded for this exception. - See Also:
getEnvironment()
getRemainingNewName
public Name getRemainingNewName()
Retrieves the "remaining new name" field of this exception, which is used when this exception is thrown during a rename() operation.
- Returns:
- The possibly null part of the new name that has not been resolved. It is a composite name. It can be null, which means the remaining new name field has not been set.
- See Also:
setRemainingNewName(javax.naming.Name)
setRemainingNewName
public void setRemainingNewName(Name newName)
Sets the "remaining new name" field of this exception. This is the value returned by getRemainingNewName()
.
newName
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 newName
is made and stored. Subsequent changes to name
does not affect the copy in this NamingException and vice versa.
- Parameters:
-
newName
- The possibly null name to set the "remaining new name" to. If null, it sets the remaining name field to null. - See Also:
getRemainingNewName()
getAltName
public Name getAltName()
Retrieves the altName
field of this exception. This is the name of the resolved object, relative to the context altNameCtx
. It will be used during a subsequent call to the javax.naming.spi.ObjectFactory.getObjectInstance
method.
- Returns:
- The name of the resolved object, relative to
altNameCtx
. It is a composite name. If null, then no name is specified. - See Also:
-
setAltName(javax.naming.Name)
,getAltNameCtx()
,ObjectFactory.getObjectInstance(java.lang.Object, javax.naming.Name, javax.naming.Context, java.util.Hashtable<?, ?>)
setAltName
public void setAltName(Name altName)
Sets the altName
field of this exception.
- Parameters:
-
altName
- The name of the resolved object, relative toaltNameCtx
. It is a composite name. If null, then no name is specified. - See Also:
-
getAltName()
,setAltNameCtx(javax.naming.Context)
getAltNameCtx
public Context getAltNameCtx()
Retrieves the altNameCtx
field of this exception. This is the context relative to which altName
is named. It will be used during a subsequent call to the javax.naming.spi.ObjectFactory.getObjectInstance
method.
- Returns:
- The context relative to which
altName
is named. If null, then the default initial context is implied. - See Also:

setAltNameCtx(javax.naming.Context)
,getAltName()
,ObjectFactory.getObjectInstance(java.lang.Object, javax.naming.Name, javax.naming.Context, java.util.Hashtable<?, ?>)
setAltNameCtx
public void setAltNameCtx(Context altNameCtx)
Sets the altNameCtx
field of this exception.
- Parameters:
-
altNameCtx
- The context relative to whichaltName
is named. If null, then the default initial context is implied. - See Also:
