Hi

When I start Active MQ 5.1, I get the folllowing exception (excerpt given
below).
I did not get this exception before.

2008-08-04 16:24:39,077 DEBUG ManagementContext              - Failed to

2008-08-04 16:24:39,093 INFO  BrokerService                  - ActiveMQ
5.1.0 JMS Message Broker (localhost) is starting

My activemq.xml file (snippet) is as follows:
<broker xmlns="http://activemq.apache.org/schema/core" useJmx="true"
persistent="false">
        <!-- Use the following to configure how ActiveMQ is exposed in JMX
        <managementContext>
            <managementContext  createConnector="false"/>
            <managementContext connectorPort="8007"/>
        </managementContext>
        -->
        <!-- The transport connectors ActiveMQ will listen to -->
        <transportConnectors>
            <transportConnector name="openwire"
uri="tcp://localhost:2506?maxInactivityDuration=-1"/>
        </transportConnectors>
</broker>

activemq-admin:
if [ -z "$ACTIVEMQ_OPTS" ] ; then
  ACTIVEMQ_OPTS="-Xmx512M -Xms512M  -XXnosystemgc -Xgcprio:deterministic
-XpauseTarget:10ms -Xverbose:gc,referents
-Dorg.apache.activemq.UseDedicatedTaskRunner=true"
fi

 exec "$JAVACMD" $ACTIVEMQ_DEBUG_OPTS $ACTIVEMQ_OPTS
-Dactivemq.classpath="${ACTIVEMQ_CLASSPATH}"
-Dactivemq.home="${ACTIVEMQ_HOME}" -jar "${ACTIVEMQ_HOME}/bin/run.jar" $@


1) Can someone let me know if I am configuring wrongly?

When I uncomment the managementContext, the exception does not occur. But at
shutdown, I get exception, Connection Refused.

After shutting down, I checked using netstat -an|grep 1099. There was no
service running.
Or there was no listeners.
tcp        0      0 :::1099                     :::*                       
LISTEN

Once again I started to get the same exception.

Thanks & appreciate your help.
