activemq启动不成功的问题
The embedded ActiveMQ in ServiceMix is configured to use network multicasts to discover other broker instances on the network. Sometimes, multicasts are disabled by policy, causing this exception:

ERROR - BrokerService - Failed to start ActiveMQ JMS Message Broker. Reason: java.net.SocketException: error setting options

The solution is to disable the multicast feature for ActiveMQ. In conf/activemq.xml, change...

<transportConnectors>
<transportConnector uri="tcp://localhost:61616" discoveryUri="multicast://default"/>
</transportConnectors>

<networkConnectors>
<networkConnector uri="multicast://default"/>
</networkConnectors>

... to ...

<transportConnectors>
<transportConnector uri="tcp://localhost:61616"/>
</transportConnectors>

<networkConnectors>
</networkConnectors>
