Build Requirements
------------------

 1. JDK 1.6.0_13 or higher
 2. Ant 1.7.1 or higher


Building Message Queue with Ant
-------------------------------

 1. Unzip the Message Queue source-code zip bundle.

    	unzip <MQ source-code file>.zip

 2. Make sure you have 'wget' in your PATH.

 3. set JAVA_HOME to a JDK 1.6.0_13 or higher.
    set ANT_HOME to Ant 1.7.1 or higher.
    Add 'ant' to your PATH

 4. Bootstrap the external dependencies:  (see "Troubleshooting the Build" below if this fails)
	cd $TOP/mq
        ant bootstrap

 5. Build everything from the top:
	ant 

    Note: If executing ant returns "java.lang.OutOfMemoryError: Java heap space",
    you should set ANT_OPTS to -Xmx512m to limit the amount of heap per java process.

Message Queue Build Output
--------------------------
    
 1. After the build, a 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

    Note: File permissions were not restored in this resulting
    mq*.zip bundles so after unzipping the file, chmod the binaries 
    to be executable, if on unix.

    chmod 755 mq/bin/imq*

Runing Message Queue
--------------------

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

 2. To run the Message Queue broker:

    cd IMQ_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 IMQ_HOME/mq/examples/helloworld/helloworldmessage

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

    java HelloWorldMessage
 
	Sending Message: Hello World
	Read Message: Hello World


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

* If 'ant bootstrap' fails, you can workaround this by
  downloading the external jars files manually.

   1. Download the following files into $TOP/mq/extlib/
      http://download.java.net/maven/2/javax/javaee-api/6.0-SNAPSHOT/javaee-api-6.0-SNAPSHOT.jar
      http://download.java.net/maven/2/com/sun/grizzly/grizzly-nio-framework/1.9.18a/grizzly-nio-framework-1.9.18a.jar
      http://download.java.net/maven/2/com/sun/woodstock/dependlibs/jhall/2.0/jhall-2.0.jar
   2. Rename javaee-api-6.0-SNAPSHOT.jar to javaee-api-6.0.jar
      Rename grizzly-nio-framework-1.9.18a.jar to grizzly.jar
      Rename jhall-2.0.jar to jhall.jar
   
   Then continue to build the product by typing 'ant'.


* If executing ant returns "java.lang.OutOfMemoryError: Java heap space",
  you should set ANT_OPTS to -Xmx512m to limit the amount of heap per java process.
