Retained publications in IBM MQ classes for JMS
An IBM® MQ classes for JMS client can be configured to use retained publications.
A publisher can specify that a copy of a publication must be retained so that it can be sent to future subscribers who register an interest in the topic. This is done in IBM MQ classes for JMS by setting the integer property JMS_IBM_RETAIN to the value 1. Constants have been defined for these values in the com.ibm.msg.client.jms.JmsConstants interface. For example, if you have created a message msg, to set it as a retained publication use the following code:
// set as a retained publication
msg.setIntProperty(JmsConstants.JMS_IBM_RETAIN, JmsConstants.RETAIN_PUBLICATION);
