Run an ActiveMQ example

The following steps walk you through running an ActiveMQ example using the Java source code.

• First, ensure that you have Maven installed on the server. If you don’t, install it following these instructions:

  • Debian:

    $ sudo apt-get install maven

  • CentOS:

    $ sudo wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo $ sudo yum install apache-maven

• Next, activate a Maven profile. To do this, modify the Maven settings.xml file (usually located in /etc/maven/settings.xml or /etc/maven2/settings.xml, although the path might differ on your server) and include the following:

  <profiles>
    ...
    <profile>
      <id>env-dev</id>
      <activation>
        <property>
          <name>target-env</name>
          <value>dev</value>
        </property>
      </activation>
      <properties>
        <maven.compiler.compilerVersion>1.7</maven.compiler.compilerVersion>
        <maven.compiler.fork>true</maven.compiler.fork>
      </properties>
    </profile>
  </profiles>
  
   <activeProfiles>
    <activeProfile>env-dev</activeProfile>
  </activeProfiles>
  

• Go to the examples/ folder and install it using maven:

  $ cd /opt/bitnami/activemq/examples/amqp/java
  $ sudo mvn install
  

• Export the environment variables you need and run the example. Note that you can obtain your server’s private IP address by using the /sbin/ifconfig command.

  $ export ACTIVEMQ_USER=admin
  $ export ACTIVEMQ_PASSWORD=PASSWORD
  $ export ACTIVEMQ_HOST=SERVER-IP
  $ java -cp target/amqp-example-0.1-SNAPSHOT.jar example.Listener &
  $ java -cp target/amqp-example-0.1-SNAPSHOT.jar example.Publisher
  

Execute the Listener and Publisher on different machines. You should now see the example running.
