Build Requirements
------------------
To build this Message Queue source bundle, you will need:

1. Maven 3.6.3  (http://maven.apache.org/download.html)
2. JDK 21 or newer (e.g. https://www.oracle.com/java/technologies/javase-downloads.html)


Message Queue Build Instructions
--------------------------------

1. Set up your settings.xml file in <user.home>/.m2/settings.xml so that 
   you can proxy to Maven Central at https://repo1.maven.org/maven2/
   Build artifacts are downloaded from Maven Central.
   If you are not behind a firewall, you will not need to set up a proxy.

<settings>
  <!-- Example proxies setup. Use your proxy setting if you need to proxy to maven-central -->
  <proxies>
     <proxy>
      <active>true</active>
      <protocol>http</protocol>
        <host>proxy-host</host>
        <port>80</port>
     </proxy>
  </proxies>
</settings>

2. Unzip the source bundle and set JAVA_HOME
      unzip mq5.1.1-source.zip
      and set JAVA_HOME.

3. Build the source and distribution.
      cd mq5.1.1-source/
      mvn clean install

4. If you get a java OutOfMemory Error while running the mvn command, 
   set MAVEN_OPTS to "-Xmx512m -Xms256m -XX:MaxPermSize=512m".


Message Queue Build Output
--------------------------

 1. After the build, a runnable build image of Message Queue is at:
        $TOP/mq/dist/mq

 2. A zip bundle of that image is at:
        $TOP/mq/dist/bundles/mq<version>*.zip
  . A tar bundle of that image is at:
        $TOP/mq/dist/bundles/mq<version>*.tar


Running Message Queue
--------------------

 1. From this point, MQ_HOME is considered to be $TOP/mq/dist/mq

 2. To run the Message Queue broker:

    cd MQ_HOME/bin
    ./imqbrokerd -tty [-javahome "<javahome>"] (unix)
    .\imqbrokerd -tty [-javahome "<javahome>"] (windows)

 3. To run a Message Queue client:

    (In the mq/examples directory, run the HelloWorldMessage sample program
    to verify the build was successful.)

    cd MQ_HOME/mq/examples/helloworld/helloworldmessage

    set CLASSPATH to include
        $MQ_HOME/lib/jms.jar
        $MQ_HOME/lib/imq.jar
        $MQ_HOME/examples/helloworld/helloworldmessage

    java HelloWorldMessage

        Sending Message: Hello World
        Read Message: Hello World


Troubleshooting the Build
-------------------------

1. If executing mvn returns "java.lang.OutOfMemoryError: Java heap space",
   you should set MAVEN_OPTS to "-Xmx512m -Xms256m -XX:MaxPermSize=512m".

2. If you build on Windows, your distribution will only run on
   Windows.  If you build on Unix, your distribution will only run on
   Unix or in a shell emulator on Windows.
