Question

I am trying to use activemq in my application, but keep getting an error when I try and connect to localhost:

log4j:WARN No appenders could be found for logger (org.springframework.core.env.StandardEnvironment).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

There is a file that should be run to start it up (active mq) and this is a .bat file on windows machines. When you run it then it starts and you leave it running in the command prompt.

At home I have a mac and using the mac equivalent the terminal just prints:

Last login: Mon Oct 29 19:57:15 on ttys000
(null):~ rickilambert$ /Users/rickilambert/Downloads/apache-activemq-5.7.0/bin/macosx/activemq ; exit;
Usage: /Users/rickilambert/Downloads/apache-activemq-5.7.0/bin/macosx/activemq { console | start | stop | restart | status | dump }
logout

[Process completed]

Can anyone please help me to get this thing up and running?

Your application is not able to connect to activemq. Check that your activemq is running and listening on localhost 61616.

You can try using: netstat -a to check if the activemq process has started. Or try check if you can access your actvemq using admin page: localhost:8161/admin/queues.jsp

On mac you will start your activemq using:

$ACTMQ_HOME/bin/activemq start 

Or if your config file (activemq.xml ) if located in another location you can use:

$ACTMQ_HOME/bin/activemq start xbean:file:${location_of_your_config_file}

In your case the executable is under: bin/macosx/activemq so you need to use: $ACTMQ_HOME/bin/macosx/activemq start
