Class TimeStampingBrokerPlugin

  • All Implemented Interfaces:
    Broker, BrokerPlugin, Region, org.apache.activemq.Service

    public class TimeStampingBrokerPlugin
    extends BrokerPluginSupport
    A Broker interceptor which updates a JMS Client's timestamp on the message with a broker timestamp. Useful when the clocks on client machines are known to not be correct and you can only trust the time set on the broker machines. Enabling this plugin will break JMS compliance since the timestamp that the producer sees on the messages after as send() will be different from the timestamp the consumer will observe when he receives the message. This plugin is not enabled in the default ActiveMQ configuration. 2 new attributes have been added which will allow the administrator some override control over the expiration time for incoming messages: Attribute 'zeroExpirationOverride' can be used to apply an expiration time to incoming messages with no expiration defined (messages that would never expire) Attribute 'ttlCeiling' can be used to apply a limit to the expiration time
