However, I do not how to do this in Spring configuration. Below is my

That way, I wonder whether I should start with ActiveMQ or just "ignore" it altogether and start by teaching myself Apollo. Is Apollo as feature-complete as ActiveMQ? Does it implement JMS 2.0 (I see that ActiveMQ got stuck with 1.1)? Will I be missing something really important? Also, how does Kafka compare to these two solutions? 回答1: Apache ActiveMQ is a great workhorse full of features and nice stuff. It's not the

Ok..So I have started studying about MQ and its purpose/usecase etc... My existing application (Web made using JSP etc..) uses RestFUL interface to communicate with a remote server and to post/receive data from the server. We often have to deal with the connectivity of the remote server.The synchronization problem is always there.. Message sent from our end.But Remote server went down. Or vice versa. I came across the MQ thing and found it to be reliable when delivering and receiving messages from remote server is concerned. But again, using REST I think the entire need for MQ appears to be a

Aas part of the application, I have a monitoring thread that monitors a directory. Instead of having to kill the process to shutdown the activeMQ server, I introduced a check for a "STOP" file and if the file exists, the server would shutdown. The shutdown I am trying to accomplish by calling the stop function on the broker. (broker.stop() ) This seems to shutdown the

I've been working with JMS and ActiveMQ. Everything is working wonders. I am not using spring, nor can I. The interface javax.jms.MessageListener has only one method, onMessage . From within a implementation, there is a chance an exception will be thrown. If in fact an exception gets thrown, then I say the message wasn't properly processed and needs to be re-tried. So, I need ActiveMQ to wait for a little while and then, retry. i.e. I need the thrown exception to rollback the JMS transaction. How can I accomplish such a behaviour? Maybe there is some configuration in ActiveMQ I wasn't able to

I've tried downloading the binary and source with no luck. Currently I have downloaded the source, run "mvn clean install -Dmaven.test.skip=true" and mvn reported successful installation. I then hunted around in my .m2 folder found apache-activemq-5.5.1-bin.tar.gz and extracted it to my home/USERNAME dir and attempted to run "bash bin/activemq start" only to receive the following error.

I also replaced the ACTIVEMQ_SUNJMX line in bin/activemq to enable JMX: ACTIVEMQ_SUNJMX_START="-Dcom.sun.management.jmxremote.port=1099 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false" Then I query JMX via the following code: try { JMXConnector connector = JMXConnectorFactory.connect(new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi")); connector.connect(); MBeanServerConnection
