The Store mediator enqueues messages passing through its mediation sequence in a given message store. It can serve as a dead letter channel if it is included in a fault sequence and if its message store is connected to a message processor that forwards all the messages in the store to an endpoint.


The Store mediator is a content aware mediator.

<axis2ns1:store xmlns:axis2ns1="" messageStore="string" sequence="string"></axis2ns1:store>
