Examples of org.mule.exception.DefaultMessagingExceptionStrategy

org.mule.exception.DefaultMessagingExceptionStrategy
This is the default exception handler for flows and services. The handler logs errors and will forward the message and exception to an exception endpoint if one is set on this Exception strategy. If an endpoint is configured via the element, a Dead Letter Queue pattern is assumed and so the transaction will commit. Otherwise, the transaction will rollback, possibly causing the source message to be redelivered (depends on the transport).
