For upcoming ActiveMQ 5.4.0 release we did a lot of work to make it a better citizen in OSGi land. Let’s walk through some of the stuff you can do now. First of all download and install recently released Apache Karaf 2.0.0.
Now if you want to play with all these stuff before the ActiveMQ 5.4.0 is officially released, you need to edit
${KARAF_HOME}/etc/org.ops4j.pax.url.mvn.cfg
and add
https://repository.apache.org/content/repositories/snapshots/
to the list of available repositories.
Once in the Felix runtime, you can now install all these new “features” by doing something like
karaf@root> features:addUrl mvn:org.apache.activemq/activemq-karaf/5.4-SNAPSHOT/xml/features
Of course, when 5.4.0 is released (and for all newer versions), you should only change the appropriate version in the url above.
You want to install the broker? Easy. Just type
karaf@root> features:install activemq-spring
and it’s there. Also, if you prefer to use Blueprint instead of Spring you can do
karaf@root> features:install activemq-blueprint
Once installed, the broker can be started with
karaf@root> activemq:create-broker
(add --type blueprint if you wish to use blueprint configuration).
Of course, no ActiveMQ installation is complete without Web Console. To monitor our installed broker, we should take the following steps:
- Install war feature
karaf@root> features:install war - Configure system properties, by adding the following snippet
webconsole.type=properties webconsole.jms.url=tcp://localhost:61616 webconsole.jmx.url=service:jmx:rmi:///jndi/rmi://localhost:1099/karaf-root webconsole.jmx.user=karaf webconsole.jmx.password=karafto
etc/system.properties - Install and run the web console
karaf@root> features:install activemq-web-console.
- Visit the console at http://localhost:8181/activemqweb/ and enjoy.
