public class LookupUnmarshalException extends AtomicException
MarshalledObject, different
exceptions can occur. An IOException can occur while
deserializing the object from its internal representation. A
ClassNotFoundException can occur if, while deserializing
the object from its internal representation, either the class file of
the object cannot be found, or the class file of either an interface
or a class referenced by the object being deserialized cannot be found.
Typically, a ClassNotFoundException occurs when the codebase
from which to retrieve the needed class file is not currently available.
This class provides a mechanism that clients of the lookup discovery
service may use for efficient handling of the exceptions that may
occur when unmarshalling elements of a set of marshalled instances
of the ServiceRegistrar interface. When elements in such
a set are unmarshalled, the LookupUnmarshalException class
may be used to collect and report pertinent information generated when
failure occurs while unmarshalling the elements of the set.
The information that may be of interest to entities that receive this
exception class is contained in the following fields: a set of
ServiceRegistrar instances in which each element is the
result of a successful unmarshalling attempt, a set of marshalled instances
of ServiceRegistrar in which each element could not be
successfully unmarshalled, and a set of exceptions (IOException,
ClassNotFoundException, or some unchecked exception) in which
each element corresponds to one of the unmarshalling failures.
Thus, when exceptional conditions occur while unmarshalling a set of
marshalled instances of ServiceRegistrar, this class can
be used not only to indicate that an exceptional condition has occurred,
but also to provide information that can be used to perform error handling
activities such as: determining if it is feasible to continue with
processing, reporting exceptions, attempting recovery, and debugging.
Note that this exception class should be used only to report exceptional
conditions occurring when unmarshalling a set of marshalled instances
of the ServiceRegistrar interface.

ServiceRegistrar, where each element of the array
corresponds to a successfully unmarshalled object. Note that a copy
is returned on each invocation of this method.ServiceRegistrar, where
each element corresponds to a successfully unmarshalled object.public MarshalledObject[] getMarshalledRegistrars()
MarshalledObject, where each element of the array is a
marshalled instance of the ServiceRegistrar interface,
and corresponds to an object that could not be successfully
unmarshalled. Note that a copy is returned on each invocation

occurred while attempting to unmarshal the object.public Throwable[] getExceptions()
Throwable, where each element of the array corresponds
to one of the exceptions that occurred during the unmarshalling
process. Note that a copy is returned on each invocation
of this method.
Each element in the return set should be an instance of
IOException, ClassNotFoundException, or
some unchecked exception. Additionally, there should be a one-to-one
correspondence between each element in the array returned by this method
and the array returned by the getMarshalledRegistrars
method. That is, the i-th element of the set returned by this method
should be an instance of the exception that occurred while attempting
to unmarshal the i-th element of the set returned by the method
