The <broker> element is used to configure the ActiveMQ broker.

-->

<!-- The constantPendingMessageLimitStrategy is used to prevent

slow topic consumers to block producers and affect other consumers

by limiting the number of messages that are retained

For more information, see:

http://activemq.apache.org/slow-consumer-handling.html

<!--

The managementContext is used to configure how ActiveMQ is exposed in

JMX. By default, ActiveMQ uses the MBean server that is started by

the JVM. For more information, see:

http://activemq.apache.org/jmx.html

</managementContext>

<!--

Configure message persistence for the broker. The default persistence

mechanism is the KahaDB store (identified by the kahaDB tag).

For more information, see:

http://activemq.apache.org/persistence.html

-->

</persistenceAdapter>

<!--

The systemUsage controls the maximum amount of space the broker will

use before disabling caching and/or slowing down producers. For more information, see:

http://activemq.apache.org/producer-flow-control.html

</memoryUsage>

</storeUsage>

</tempUsage>

The transport connectors expose ActiveMQ over a given protocol to

clients and other brokers. For more information, see:

http://activemq.apache.org/configuring-transports.html

Enable web consoles, REST and Ajax APIs and demos

The web consoles requires by default login, you can disable this in the jetty.xml file

Take a look at ${ACTIVEMQ_HOME}/conf/jetty.xml for more details
