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
- To build the example, Maven must be configured to use the Red Hat repository or a local repository.
- You must install the examples.
-
You must have a message broker listening for connections on
localhost. It must have anonymous access enabled. For more information, see Starting the broker. -
You must have a queue named
queue. For more information, see Creating a queue.
3.2. Running Hello World
The Hello World example calls createConnection() for each character of the string "Hello World", transferring one at a time. Because AMQ JMS Pool is in use, each call reuses the same underlying JMS Connection object.
Procedure
Use Maven to build the examples by running the following command in the
<source-dir>/pooled-jms-examplesdirectory.mvn clean package dependency:copy-dependencies -DincludeScope=runtime -DskipTests
$ mvn clean package dependency:copy-dependencies -DincludeScope=runtime -DskipTestsCopy to Clipboard Copied! The addition of
dependency:copy-dependenciesresults in the dependencies being copied into thetarget/dependencydirectory.Use the
javacommand to run the example.On Linux or UNIX:
java -cp "target/classes:target/dependency/*" org.messaginghub.jms.example.HelloWorld
$ java -cp "target/classes:target/dependency/*" org.messaginghub.jms.example.HelloWorldCopy to Clipboard Copied! On Windows:
> java -cp "target\classes;target\dependency\*" org.messaginghub.jms.example.HelloWorld
> java -cp "target\classes;target\dependency\*" org.messaginghub.jms.example.HelloWorldCopy to Clipboard Copied!
Running it on Linux results in the following output:
java -cp "target/classes/:target/dependency/*" org.messaginghub.jms.example.HelloWorld
$ java -cp "target/classes/:target/dependency/*" org.messaginghub.jms.example.HelloWorld
