org.qbroker.persister.Persister

org.qbroker.persister.DocumentPersister

All Implemented Interfaces:

MessagePersister

public class DocumentPersister
extends Persister

DocumentPersister listens to an XQueue and receives JMS Messages from it. Either it stores the JMS Messages on a remote server as documents, or it downloads documents from a remote server according to the content of the messages and puts the content back to the messages in their body. DocumentPersister supports flow control and allows object control from its owner. It is fault tolerant with retry and idle options.

Currently, it only supports MongoDB and Riak.
