I downloaded Active MQ 10.2.0 (for Windows) and unzipped it. My environment: Windows 7 (64-bit) JDK 1.7
When I execute "activemq.bat start" command from the \bin directory, the following exception is shown in the log: 2016-04-01 16:32:04,123 | ERROR | Failed to start Apache ActiveMQ ([localhost, ID:HP_LAPTOP-57850-1459546323874-0:1], java.net.URISyntaxException: Illegal character in hostname at index 7: ws://HP_LAPTOP:61614?maximumConnections=1000&wireFormat.maxFrameSize=104857600) | org.apache.activemq.broker.BrokerService | WrapperSimpleAppMain 2016-04-01 16:32:04,130 | INFO | Apache ActiveMQ 5.11.1 (localhost, ID:HP_LAPTOP-57850-1459546323874-0:1) is shutting down | org.apache.activemq.broker.BrokerService | WrapperSimpleAppMain 2016-04-01 16:32:04,134 | INFO | Connector openwire stopped | org.apache.activemq.broker.TransportConnector | WrapperSimpleAppMain 2016-04-01 16:32:04,138 | INFO | Connector amqp stopped | org.apache.activemq.broker.TransportConnector | WrapperSimpleAppMain 2016-04-01 16:32:04,143 | INFO | Connector stomp stopped | org.apache.activemq.broker.TransportConnector | WrapperSimpleAppMain 2016-04-01 16:32:04,147 | INFO | Connector mqtt stopped | org.apache.activemq.broker.TransportConnector | WrapperSimpleAppMain 2016-04-01 16:32:04,150 | INFO | Connector ws stopped | org.apache.activemq.broker.TransportConnector | WrapperSimpleAppMain 2016-04-01 16:32:04,154 | INFO | PListStore:[C:\Apache_ActiveMQ\apache-activemq-5.11.1\bin\win64\..\..\data\localhost\tmp_storage] stopped | org.apache.activemq.store.kahadb.plist.PListStoreImpl | WrapperSimpleAppMain 2016-04-01 16:32:04,155 | INFO | Stopping async queue tasks | org.apache.activemq.store.kahadb.KahaDBStore | WrapperSimpleAppMain 2016-04-01 16:32:04,156 | INFO | Stopping async topic tasks | org.apache.activemq.store.kahadb.KahaDBStore | WrapperSimpleAppMain 2016-04-01 16:32:04,158 | INFO | Stopped KahaDB | org.apache.activemq.store.kahadb.KahaDBStore | WrapperSimpleAppMain 2016-04-01 16:32:04,354 | INFO | Apache ActiveMQ 5.11.1 (localhost, ID:HP_LAPTOP-57850-1459546323874-0:1) uptime 0.582 seconds | org.apache.activemq.broker.BrokerService | WrapperSimpleAppMain 2016-04-01 16:32:04,356 | INFO | Apache ActiveMQ 5.11.1 (localhost, ID:HP_LAPTOP-57850-1459546323874-0:1) is shutdown | org.apache.activemq.broker.BrokerService | WrapperSimpleAppMain Note.
