## javax.jms
Interface ExceptionListener

public interface ExceptionListener

If a JMS provider detects a serious problem with a `Connection` object, it informs the `Connection` object's `ExceptionListener`, if one has been registered. It does this by calling the listener's `onException` method, passing it a `JMSException` argument describing the problem.

An exception listener allows a client to be notified of a problem asynchronously. Some connections only consume messages, so they would have no other way to learn that their connection has failed.

A JMS provider should attempt to resolve connection problems itself before it notifies the client of them.
