Chapter 3. Getting started

This chapter guides you through the steps to set up your environment and run a simple messaging program.

3.1. Prerequisites

3.2. Running Hello World

The Hello World example creates a connection to the broker, sends a message containing a greeting to the queue queue, and receives it back. On success, it prints the received message to the console.


  1. Use Maven to build the examples by running the following command in the <source-dir>/qpid-jms-examples directory:

    $ mvn clean package dependency:copy-dependencies -DincludeScope=runtime -DskipTests

    The addition of dependency:copy-dependencies results in the dependencies being copied into the target/dependency directory.

  2. Use the java command to run the example.

    On Linux or UNIX:

    $ java -cp "target/classes:target/dependency/*" org.apache.qpid.jms.example.HelloWorld

    On Windows:

    > java -cp "target\classes;target\dependency\*" org.apache.qpid.jms.example.HelloWorld

For example, running it on Linux results in the following output:

$ java -cp "target/classes/:target/dependency/*" org.apache.qpid.jms.example.HelloWorld
Hello world!

The source code for the example is in the <source-dir>/qpid-jms-examples/src/main/java directory. The JNDI and logging configuration is in the <source-dir>/qpid-jms-examples/src/main/resources directory.
