I had installed ActiveMQ 4.1 on server with JDK 1.4.2 update 12. ActiveMQ can start and running, however, it failed to start JMX.
Below is the logs: ============================================== 2007-06-14 12:32:26,609 [main ] INFO BrokerService - ActiveMQ Message Broker (localhost, ID:centraldb-4923-1181797195625-1:0) is shutting down 2007-06-14 12:32:26,609 [main ] INFO NetworkConnector - Network Connector default-nc Stopped 2007-06-14 12:32:35,562 [main ] INFO BrokerService - ActiveMQ 4.1.0-incubator JMS Message Broker (localhost) is starting 2007-06-14 12:32:35,562 [main ] INFO BrokerService - For help or more information please see: http://incubator.apache.org/activemq/ 2007-06-14 12:32:36,515 [main ] INFO JDBCPersistenceAdapter - Database driver recognized: [apache_derby_embedded_jdbc_driver] 2007-06-14 12:32:37,984 [main ] INFO DefaultDatabaseLocker - Attempting to acquire the exclusive lock to become the Master broker 2007-06-14 12:32:38,000 [main ] INFO DefaultDatabaseLocker - Becoming the master on dataSource: [EMAIL PROTECTED] 2007-06-14 12:32:38,343 [main ] INFO KahaStore - Kaha Store deleted data directory activemq-data\localhost\tmp_storage 2007-06-14 12:32:38,453 [main ] INFO TransportServerThreadSupport - Listening for connections at: tcp://centraldb:61616 2007-06-14 12:32:38,453 [main ] INFO TransportConnector - Connector openwire Started 2007-06-14 12:32:38,593 [JMX connector ] WARN ManagementContext - Failed to start jmx connector: javax.naming.CommunicationException [Root exception is java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: java.net.MalformedURLException: no protocol: JMS/Queue/bin/../conf/] 2007-06-14 12:32:38,625 [main ] INFO TransportServerThreadSupport - Listening for connections at: ssl://centraldb:61617 2007-06-14 12:32:38,625 [main ] INFO TransportConnector - Connector ssl Started 2007-06-14 12:32:38,640 [main ] INFO TransportServerThreadSupport - Listening for connections at: stomp://centraldb:61613 2007-06-14 12:32:38,640 [main ] INFO TransportConnector - Connector stomp Started 2007-06-14 12:32:38,640 [main ] INFO NetworkConnector - Network Connector default-nc Started 2007-06-14 12:32:38,640 [main ] INFO BrokerService - ActiveMQ JMS Message Broker (localhost, ID:centraldb-1991-1181804555125-1:0) started =============================================== any idea how to solve this? -- View this message in context: http://www.nabble.com/Failed-to-start-jmx-connector-tf3920420s2354.html#a11116167 Sent from the ActiveMQ - User mailing list archive at Nabble.com.
