All Implemented Interfaces:

Serializable

public class ChannelException
extends Exception

Channel Exception
A channel exception is thrown when an internal error happens somewhere in the channel.
When a global error happens, the cause can be retrieved using getCause()

If an application is sending a message and some of the recipients fail to receive it, the application can retrieve what recipients failed by using the getFaultyMembers() method. This way, an application will always know if a message was delivered successfully or not.
