Examples of org.apache.synapse.endpoints.FailoverEndpoint

org.apache.synapse.endpoints.FailoverEndpoint
FailoverEndpoint can have multiple child endpoints. It will always try to send messages to current endpoint. If the current endpoint is failing, it gets another active endpoint from the list and make it the current endpoint. Then the message is sent to the current endpoint and if it fails, above procedure repeats until there are no active endpoints. If all endpoints are failing and parent endpoint is available, this will delegate the problem to the parent endpoint. If parent endpoint is not available it will pop the next FaultHandler and delegate the problem to that.
