Environment

Release : 21.2

Cause

There was a formatting error in the /opt/IMDataAggregator/broker/apache-activemq-5.16.2/conf/activemq.xml file 

Resolution

Updated the /opt/IMDataAggregator/broker/apache-activemq-5.16.2/conf/activemq.xml file and changed the end of the file. 

Took the # out and then separated the comment lines

From this: 
 <!-- 
        Enable web consoles, REST and Ajax APIs and demos
        
        Take a look at ${ACTIVEMQ_HOME}/conf/jetty.xml for more details 
    -->
  #    
  <!--<import resource="jetty.xml"/>-->
      

</beans><!-- END SNIPPET: example -->
