org.qbroker.persister.Persister

org.qbroker.persister.JDBCPersister

All Implemented Interfaces:

MessagePersister

public class JDBCPersister
extends Persister

JDBCPersister listens to an XQueue and receives JMS Messages from it. Either it updates the JDBC data source based on the JMS Message, or it queries for data records from the JDBC data source according to the content of the messages and puts back the messages with the data content to their body. JDBCPersister supports flow control and allows object control from its owner. It is fault tolerant with retry and idle options.
